Would an improper plug make a Blaster motor have a knocking sound? I got the wrong plug from the Yami dealer (same plug/ except no resistor). When I installed it it ran with a loud knock. Changed back to the old one, no knock? Huh?

 

i havent ever heard of a knocking being caused by a plug. maybe tho

 

Sounds like detonation. did you increase compression?

 

I think your valves need adjusting, jk. I havent heard of that either [img]i/expressions/face-icon-small-blush.gif[/img]

 

i had a blaster once apon a time, and u probly just have bad gass in the tank. dont ever run ethanol gas in a 2 stroke, thats probly what your problem is.

 

LOL! Might be those troublesome muffler bearings, too!
