xtm mammoth tuning probs + pull start

[ivan]

my xtm mammoth seems to be tuned ok it accelarts good and theres a good top speed but alot off smoke out the exhaust when i accel is this normal and the pull start keeps sliping like i pull it and it does not tick the engine over i have to turn the crank shaft then i can pull it and it tickes over is it because off the one way bearing???

Allot of smoke w/ good performance is GREAT ..

You might have a lot of excess oil built up on the pull start causing it to slip
take the pull start off and clean the shaft and pull start

does it matter what % oil the fuel contains

 

[Double-O-Zilch]

Yes, the higher the oil content the better chance it would give you OWB trouble.

clean ur one way and starter shaft under the pullstart with some DA then get this grease that is specificially made for one ways, causes them to not slip even if the bearing is shot

i have changed the fuel iam using as i think the fuel it ran on before was no good anyways i have changed to 20% tornado fuel but it is bogging when i go to accel and the cooling head is really cool when it gets past bogging it goes well with a good amount of smoke coming out the exhaust what can i do to fix this

and i have cleaned the pullstart and working well thx:resp:
