Questions?? .12 Jamming Turning on Backwards

Hi, new to the forum. My friend has a cd3 with a .12 Jamming motor on it. Yesterday we turned it on but the box start motor was inverted so he accidently turned it on backwards. Now it turns on easily but backwards. Any advice? We have tried adding more shims, reducing nitro fuel % from 30 to 20, and using a diffrent glow plug with no results. What do you guys recommend?

Thanks in Advance, Any advice will be appreciated

I was just looking at a picture of the motor online and my friend has the carb reverse to what it looks like in the picture. The needle is on the left and the slide mechanism is on the right, could that be the problem?

if you are looking at the front bearing, the carnkshaft should turn anti-clockwise direction. Which direction you are now seeing the shaft turning?

Were turning it clockwise. Since when we roll the car on the floor the flywheel turns clockwise. Is this correct?

Thanks for responding.

the engine runs counter clockwise when looking at the front bearing and carb. The engine wont run the other way other than idle.

Ok thanks, We were trying to turn it on clockwise, and my friend also had something wrong with the differentials.

Thanks for all the replies.

Well its not going too.. Learn to read please..

Reverse the polarity on either your rotostart or your starter box, making the motor spin the other way.. This will solve your wheels spinning the wrong way too.
