Well, I pulled the head off and examined the piston, cylinder and valves. Everything was in great shape even had a new head gasket in place. Movement was accurate (piston and valve timing) are fluid for the piston and valves. Piston is machine stamped .010 so I am assuming that this is due to a reboring of the cylinder?

In any case, dunno what else might be an issue.
Got Fuel, compression, air, sparkies. -- but no go! BTW, muffler is missing - just has extension pipe out of the block. Thanks for your help.

Well if you Got Fuel to the plug, compression, & spark to the plug and you say it is timed correctly then there is no way that it should not run. Even if it is not exactly in true time it should at least Pop, Fart, Belch or backfire through the carb or exhaust.

OK I get it thanks JohnBron for the update! I will check why it just don't run when I have everything in place and working --- Maybe I forgot to plug up the REPEATING WIDGET next time.
HAHAHA

No problem --- just kidding... sometimes dialup connections will do that if it is slow and you hit the Submit button and few times.

Thanks --- I dont know what the problem is.

Any luck yet Andy? Figure you HAVE to be close, there is not much more to go. Any luck on that flywheel? If it was a newer motor, I would say your flywheel key is sheared, but I don't eaven know if that motor uses one.

Hi Andy
You say you have spark but you didn't say where you checked it. If I remember correctly your working on a model "A" Briggs and they use the large plug , I have had several problems with these plugs going dead,( even new ones)when they have compression on them , something else to try

Archie,

Where did I check the spark? I checked it outside the cylinder - by testing the spark plug first and then the plug near post on head or block. Nice clean blue spark. This is a COM 8 Champion plug. I was told by many people that these COM plugs are far superior than the "regular" plugs they make today. I am not advocating that this could not be the problem, but how else can check spark to eliminate this as a potential issue? I invite your insight and reply --- Thanks for posting!

The only sure way is with a spark plug tester but I haven't seen one in years soooo try one out of another engine or try yours in another engine that you know is running , btw make sure the points are right on 0.20 if they get even a little tight that engine can kick back unbelievably hard for a single cyl engine my "B" threw the crank about 6 ft across the shop

threw the crank for improper point gap? That sounds wild! outta here -----> Will work on it and see what I can find out. Have not had time lately to tinker with it. Maybe this weekend.

Well, it looks like the coil is bad. Sorry for me since they are really expensive. Funny thing is that I do get a nice clean sparkie, but even with that some people have stated that the coil might be the culprit on this machine. Dont know --- just never turns over --- even with fuel in the cylinder. Good compression. So if air is good, compression is good, fuel is there, I guess it must be the sparkie.

In any case, thanks for all of the help. Guess it will just sit unless someone has a spare coil for a Model A or knows of a decent *egad!* external coil to use. :money:

Thanks!
Andy
