I picked up 9.9 and it appears the kill switch has been messed with. Other than that, it looks like brand new, but I get no spark when I try to start it
Hey fast bullet, you sounded like the voice of experience, so I borrowed my millwright buddy's digital compression tester (quickly while he is still at work) .
If I got 154 psi on the top cyl.
&
I got 31 psi on the bottom cyl.
Would that mean you nailed it from 100s or 1,000s miles away?
Yes, Ive run more than a can of carb cleaner thru every port I could find. Including the bottom one, although I didn't know that was the high end jet. Plus blasted it with shop air.
No, I haven't checked compression. Now that I think about it, that could be the issue. It fires on both when I rev it high, but at lower idle, it doesn't draw enough air to pull fuel. Is that how low compression would effect idle?
I have an enclosed spark tester,.but it appears to have a decent spark. When I rev it way up, it seems to pick up fuel in the bottom carb. It runs without dying on one cylinder, just not clear down to idle. And if I squirt gas in the bottom carb, it takes off and runs smooth.
Picked up an old 55EL78S. It would start an run for about 5 seconds. Then die. So I took off the carbs, cleaned them and put them back on. Then it started and ran rough, and poured gas out of the bottom carb. I decided the float was hung up and that was probably flooding out the bottom...
