Hi everyone, first post here. I'm hoping someone else might have run into this problem and has an answer for me. I have a 20 HP enduro vt twin in a Murray 46". Last year it started to drop a cylinder and now it only runs on one. I've had the head off as someone told me it was more then likely a burnt valve, but they were fine. What I found really strange is last year I ran it out of gas and about 30 seconds before it ran out it picked up that cylinder and ran perfect till it ran out. I've had both carbs apart and everything looks fine, but do I have a bad carb on that side or what do you think is going on? Thanks for any responses.

Air, Fuel, compression, spark and timing. You need to check all those things. Is the plug wet on the dead cylinder? It sounds like a fuel issue, maybe a vacuum leak in the intake manifold somewhere, just wild guesses here.

1/2 a bottle of Sea Foam did the trick!! Started hitting on that cyl about 10 minutes after I added it to the gas and ran great for a half hour after words.
