it sounds like you have an air leak. get it fixed before you blow it up.
you need a leakdown tester. look on here and find out how to make one, or you can buy one from a user on here. find the leak with it, and then you can fix it

yes its called pre-ignition
Usually caused by too low of octane fuel, an air leak, carbon build up or too hot of a spark plug heat range. The most common cause is low fuel. As the carb gets low it will lean out and that can cause a hot spot in the combustion chamber if the plug is too hot or carbon deposits
I would do a leak down test asap.
In the mean time go with a BR9ES plug and higher octane fuel if you need to use it until you get a chance to test it.

IMO I wouldn't run it at all till you find out what the issue is. There's a link on how to build and use a leak down tester in my sig below. If you don't want to build a tester pm holeshotman to buy one. I believe they are $30?
Ok thanks well all my problems right now relate to that stuff because now it aint gettin fire to the spark plug and i was told that was a bad coil, and i had some carb. problems but i think that thats fixed.
