Small Engine Troubleshooting Problems? Ask a Mechanic Now.
are you getting spark at the spark plug?
either have to have a spark tester, or pull plug with wire still on it, and have someone crank engine over while holding sprk plug edge/side to the engine. you should see spark. if not will need a ignition coil
You can also place a screwdriver in plug wire, and hold about 1/8" from engine. have someone turn engine over and see if you see spark jump from screwdriver and engine.
no problem. Let me know the outcome
okay. If you are getting spark and you are getting fuel, air will be issue. Try putting fuel into cylinder directly and see if it will start up.
Sounds like either compression is low, or there may be a valve issue. valve issue will give you spark, but improper spark timing and not allow engine to start
remove plug and squirt small amount of fuel into the cylinder. you can also pour small amount into carb or intake and try to start
If it back fired, I would re-gap the coil and also check the fly wheel key for shearing
