Before starting, I'll be cycling it with the heater. In some previous posts you said "On my new engines, before starting, I will heat cycle the engine 3 times, bring it up to 180-200 and let it cool, repeat 2 more times."
Question on that...do you have the piston at BDC, TDC, somewhere in between, or have you found that position doesn't matter at all?
Thanks....
As close to BDC as possible. Also, after heat cycling it's alway's a good idea to check head screws and carb to make sure they are tight after letting the materials expand and contract.
On another note, I just returned from Helena, Al and Alan Burtons new track "The Warehouse". All I can say is Alan and his guy's have done a great job with this new indoor facility. For anyone out there that's having nitro withdrawals already this winter, it's most definately worth the trip, they run a very efficient program along with a great track layout. Well done guy's.
