Hello, I just purchased my sled from a friend who said nothing was wrong but maybe some rings. Well, after replacing the pistons, rings, and cleaning the carbs she ran great... For about a tank of gas. Now I'm not getting good combustions out of cylinder 2 and no combustion in cylinder 3. I replaced the plugs to see if they were fouling out and my worst cylinder's spark plug boot was bad so I replaced it along with new spark plugs. I can pull the plugs out to test them and they are getting spark now. However, after I run the machine the plug does not look like it has fired at all. I reinspected all of my piston and ring work and all seems to be good. No burrs on the cylinder (plus i had the shop hone them before installation). I pulled the plug and it seems gas is making its way to the combustion chamber. I do not have a compression tester and my multi meter stopped working. Is there anything else I can check or do?
your carbs may be clogged up. clean the carbs along your main and pilot jets. and your filter hats if you havent already done so. the pilots clogg easy doesnt take much at all. i know you already did it but check em one more time. doesnt take much with these pilots they are small. and clogg very easily if theres anty debis in the tank.

A brand new plug takes a while to carbon up. You won't see anything for a few miles.
