Below are the tools I use to clean a really nasty carburetor like the one shown above . When I'm done and the mower/motorcycle/ATV runs again, I expect at minimum of one of these and on some machines it's two.... I love ethanol fuel
Depends on where you're located and where you buy it. If you buy it from a busy place that takes 2-3 fuel drops a week, it's fresher fuel, and doesn't sit in a 20,000 gallon storage tank for a month. If you live in an area where the EPA doesn't mandate "Summer Blend" fuel (like Atlanta), it doesn't start to gum up as quick sitting in your fuel tank for extended periods of time. "Summer Blend" Atlanta fuel is the worst I've seen for starting to destabilize really quick..... I'm talking 30-40 daysI've been using ethanol gas since it came out. I store it in 2 1/2 gallon plastic jugs with a little B12 and occasionally some stabil. I've never had any of the problems I'm seeing here.
I get my gas at a station in a town with 900 population. All our fuel comes out of Denver and it all has ethanol in it. My 55 year old Massey 50 loader tractor seems to love it. I can only speak about my own experiences but gas isn't one of my problems.Depends on where you're located and where you buy it.

$100-$200 is on a fairly simple removal/install on a lawn mower. ATV's and motorcycles are a whole different price range. Used to do a whole lot of GL1000 and GL1100 Goldwings with the 4-carb "rack". Cheap Chinese after market carb kit is now $100 and it's about 5 hours labor including the synchronization/tuning after the install. Most Honda shops won't even touch them now days because there is nobody in their shop that even knows how to rebuild them, much less synchronize them. Last one I did was 3 years ago, I charged the guy $600 because he was a friend and the bike was in immaculate shape for a '77. His local Honda Shop was going to "send the carbs out to a rebuilder", quoted him $1,200 with no warranty, and it was 4-6 weeks to get the bike back. Brought it to me on a trailer at 8:00AM, rode it home at about 2:00PM, and I really enjoyed the 1 hour "test ride" I took on his vintage Wing....I was the GM at a big Honda/Kawasaki shop that sold lots of ATVs and lots of dirt bikes as well as the cruisers. My mechanics absolutely hated E fuel but we made lots of money from the fuels destructive contents. IMO, ethanol is fine for regularly used and often refreshed vehicles but it sucks for any engine that is subject to sit for very long without using the fuel. Bob's picture of his Benjamins is a fraction of what we charged but that was because the labor involved in getting the carbs off and back onto most of our machines was extensive. Some of the carbs, if left sitting too long could not be brought back and had to just be replaced. Boat manufacturers that enclosed fiberglass and aluminum fuel tanks under the decks had fits because the E gass ate holes in them and often before any warranty ran out. Our sister Marine division refused to sell any ethanol fuels for outboard engines that used portable tanks and on the larger I/O and inboard engines they all had to install water separation systems. Ethanol is alcohol and alcohol attracts moisture from the atmosphere. For those who claim they like or have no issues with the garbage fuel all I can say is wait! I had 90 degrees here the other day and the following morning it was 26 degrees. Temperature fluctuations like that cause condensation to form both inside and outside of fuel tanks. Show me an additive that can make water in your tank simply disappear and I will be all in on it.
Old school, Delo 400 15w40.... "Frank's Hot Sauce" of oil, you can put that $hit in about anythingI can agree with you Bob but more importantly is the question as to what is causing the need to go into these types of carbs. IMO it certainly is related to the use of ethanol fuels coupled with lack of use or the fuels remaining in the tanks and float bowls long past the degradation of the fuel itself. Mild gumming of the carb sure can be cured by using additives on a regular basis but not much can be done if the gumming remains too long other than a complete rebuild and cleaning. I have owned and maintained lots of Yamaha TW200 motorcycles that suffered from the use of E fuel and the fuel sitting too long. The TW200 was first designed around 1986 and has not changed much since. As long as I treated them with fresh fuel and dosed the new gas with Seafoam as soon as I felt any performance issues all was fine. Up here in the frozen north country those dirt bikes get stored for 6-8 months during each winter which was the problem. Proper storage was the key for us. Some of us drained the tanks and carbs while others took different steps.
What worked best IMO was to fill the tank with fresh Non E fuel and a double dose of Seafoam followed by draining the carb and fogging it before putting it up for each winter. Our lawn equipment and boat motors here suffer from the same issues of long term winter storage and fuel degradation. We can discuss the use of ethanol in our gas until the cows come home and then move on to the other, "What oil is best" discussion.![]()
The old 50 sits in the shop year round. It only gets used to push a little snow in the winter and maybe move a bucket of gravel around in the summer, or do a little mowing with a 6' bush hog. I'd say way less than 20 hours a year. I never drain the carb or the tank. But thanks for assuming I don't have a clue, and bringing me up to speed.Kelley1, I don't know your loader tractor but for sure at 55 years old nothing about it was designed to be ethanol compliant. It is good that you are not having any issues with it---YET.
How often you use the machine and how long the fuel remains in your tank and carb would be my question. Seafoam or some other additive as a steady diet could play a roll also. I have a JD Gator that runs fine on the E fuel but again, it is used daily around the farm and it does get Seafoam in every tank and it is a FI engine and not a carb. In many of the older small engines that have rubber or some other flexible fuel lines we have found black particles clogging the jets and orifices and traced this to a breakdown of the hoses and O rings. Some plastic tanks have also deteriorated over time and aluminum tanks are much worse. More often than not we find it is the smaller stuff like weed eaters and chainsaws that take a beating unless they were designed to be E compliant. Many of those manufacturers recommend avoiding E fuels even today and they usually sell their own brands of True Fuels that are pre mixed with 91 octane Non E gas and 2 cycle oils and those companies refuse to honor any warranty repairs caused by the use of E fuel. Some autos are designed to use 10% E fuel but warn against using 15%. What Bob D said has merit and where you live geographically and how the fuel is treated from the distributor plays a role as well. I never buy my fuel for my vehicles if the tank truck is at the station delivering and I also buy my fuels from popular or busy stations rather than the ones that don't sell much and likely hold it in their tanks for much longer, freshness counts.
The real questions I have regarding Ethanol are many. Is it cheaper? Is it more environmentally friendly? Does E fuel have equal BTU ratings, IE, will our fuel consumption be increased or decreased? What about the weather where you live, places that are not subject to vast temperature swings such as AZ and the southern states Vs the frozen north states all play a part in this fuel controversy. Those who live in or near the major corn producing states will have a far different opinion than those who live elsewhere. Here in the NY Catskill mountains I prefer my corn on my dinner table but I do understand how others might feel.
Probably spent $2M over the course of my career running big fleets for oil analysis. Tested about every major brand on the market at one time or another. Nothing ever beat Delo 400I like that machine Kelley! I am surprised it is a gas rather than diesel motor.
Thanks BobD for your oil advice. I am a true blue believer in full synthetic oils in all of my engines. Not that the DELO is not a fine product but I always believed that oil is cheap compared to engines. My MCs and UTVs get Mobil 1-T4 racing full synthetic 10W40.
That's the only oil that I run in my 89 GL1500 Goldwing.My MCs and UTVs get Mobil 1-T4 racing full synthetic 10W40.

I hate to say it, but Rotella T-4 has 1,200 PPM Zinc in it (if that's what you're after), Delo 400 has 820PPM, but you can run Delo 400 much longer than T-4 before it reaches the TAN (Total Acid Number) that dictates an oil change.That's the only oil that I run in my 89 GL1500 Goldwing.

There's a big difference in the way you manage controlling water in the fuel of "Fun Toys" and the way you approach it in revenue generating assets that absolutely have to run every day and you're buying fuel from sources where you don't control the storage tank. Water in the fuel of an OTR truck can cost you a $2,000 road call/tow, water in the fuel of your ATV/dirt bike and you push it back on the trailer and go home. In a pleasure boat, somebody will eventually tow you back to the dock and you can winch/float it onto the trailer.I was referring more to additives such as Dry Gas and Heat. Both IMO are a myth in their claims of removing water from your tank. Most of the bigger pleasure boats these days come with a water separator system that you do drain periodically. I do question the emulsifier types that allow water to pass through because as we are all aware, water does not burn or compress. I have always suspected the crud you show on the carb above is the direct result of water in the fuel system and I also suspect the engine that carb was on also has a high carbon build up at the top of the cylinder and piston. Internal combustion motors and water just don't mix! Fuel tanks from motorcycles are very famous for having water sitting in them after they were stored. I have a flexible inspection camera that goes into the tanks and I can clearly see the rust forming in the welded seams. I have successfully used electrolysis to cook such tanks and it does get most of the rust out. I have never had much success with internal tank coatings on the few tanks I used them in. Water is an enemy and ethanol fuel tends to promote the intrusion of water.
I was responding to reo4675 about what he runs in his GL 1500. A lot of old school, carburated Goldwing guys, run 15W40 diesel oil...."I hate to say it, but Rotella T-4 has 1,200 PPM Zinc in it". I never mentioned Rotella T4. I use Mobil 1- T4 full synthetic but I don't have the content specs on it
