Hi everyone, So my problem is this:
I have a new to 212cc Predator engine on a Mega Moto mini bike. I removed the governor, replaced the stock lash spring's with 18lb ones, found top dead center and reset the lash valves. 5000th on the intake and 7000th on the exaust. So after everything was complete it started up, but when I hit the throttle I noticed there was no torque. It would not move forward. When I crank the throttle all the way it just sputters. It seems like it wants to go, but the engine is not cranking at its full potential. When I removed the spark plug it was completely black on the end. I did also go back into the engine and find TDC and readjusted the lash valves, hoping it would solve the problem, but it did not. Is there something wrong with the pistons? Thanx
Note: I've modified the 212cc Predator engines this same way before and never had a problem like this.
