I never run my nitro cars over 30 degrees C. I finally got to get them all out for a run yesterday. The dogs got some good exercise chasing them around the back yard, saved me taking tthem for a walk. Which 17 tooth clutch bell are people running on their evaders? Is it a harfdened steel one & what is the pitch of the teeth?

I put a post on here a few pages back on how I run my engines in. Basically as rich as the engine will go without stalling for 5 tanks at wide open throttle (the car will crawl around real slow & not rev much at all) then backing off 1/8th of a turn until it sings. Then I wind the low speed needle in till it pings off the line but doesn't increase revs at idle.

Cheers
Dicko.
