i have seen where people have just put a bolt and washer in place of the solenoid... what i dont understand is ... if you are plugging the hole... how is the engine getting gas? seems if the solenoid stops the flow when the key is turned off... arent you stopping the flow by plugging the hole with a bolt and washer? what am i missing here?

Its actually easier to just snip the end of the solenoid off and put it back in, just unhook the wire to it.

Earlier carbs before the solenoid used a short bolt to hold the bowl on - the fuel would flow into the carb thru holes in the sides of the threaded section - w/o looking at a couple of my carbs- couldnt tell if it would work or not - itd have to have holes in it to work.

Manual says to place the throttle between 1/2 & full to shut off engine.

Fuel solenoid has absolutely NOTHING to do with the float.
it's just a retractable "pin" that blocks the MAIN JET.
It has NOTHING to do with fuel ENTERING the carb bowl.
LOOK at an IPL for the engine. .You can SEE it has nothing to do with fuel filling the carb bowl.

On cold starts, you probably are taking it off choke too soon.
These carbs are jetted (too) lean and a cold engine requires a richer mixture. Pre EPA, carbs weren't jetted as lean, so cold performance wasn't quite as bad as the newer types.
(The choke is there for a reason)
