I don't know who told you that you wanted an orange spark....but they were wrong. also, I am running (standard) 87 octane(which is lower than what the standard was whe the tractor was made). What are you trying to get at by asking me if I'm using low octane fuel?? I don't understand.
By intermtant, I mean that it'll fire every now and then but won't run.
It is getting plenty of fuel, but tried some ether anyways and it didn't make any difference.
Everything has been done on the tune up end.
I'm starting to think that the cam is excessivly wore or something.
Really starting to get frustrated, just a week ago this tractor ran like a dream.
Btw, the points pin seems to be all steel. I got my mics out and the pin measured 1.5436"
I just can't figure out what's wrong. I mean it's got 120lbs rolling compression (that's at starting speed with the decompression in effect so it is much higher than this). I am getting plenty of fuel, and I have great spark.
I will try holding some sand paper against the flywheel while I'm turning the engine over.....maybe then I will be able to find the timing marks.
thanks for the advice, keep it coming.
thanks,
