I got an 84 trx 200 given to me. --new piston/rings, bored.025 over,new complete gasket set, carb kit.
followed the manual when installing the new parts. The honda sat for at least 4 years. Has good, not great , but good spark. timing looks good and lined up. cleaned gas tank. carb gets gas to it. to be sure engine is getting fuel I spray a shot of carb cleaner in the plug hole then install spark plug. Turns over , but just wont run. Is there anyone that might know what the problem might be?

 

Never mind, I got it!! Ngk instead of champion.
