If you have spark and fuel, and it wont start...look for low compression, or bad timing.

 

hey, thanks honda buster, Im taking it to my uncles but is there any way i could fix it myself, What parts?


thanks ethyan

 

well, to check for bad compresion, u need a compression tester that screws in where the spark plug goes.

 

checking compression is easy. Get a nice kit, not a 20 or $25 cheapo tester. I bought mine from Sears for I think 50 bucks. Snap-On makes a nice one too. But be sure it's one that screws into the spark plug hole, like mentioned above.

 

hey
im pretty sure its got good compression how do i check if the timing is off?

Is it old gas? Has it been sitting? Try spraying a little starting fluid in the carb.
