Hi guys
car was running perfectly today at 240-250 F so im pretty pleased!
the problem was that the 2 speed shaft was held tight with not much play in it. causing the whole spur gear system to have too much resistance to turn. which in the probably caused the 2 speed to kick in late making me having to lean the engine off for it to kick in... if that makes any sense!
still find it a touch on the rich side with the exhaust note but i believe thats how stock (pull start) kit motors are run.
thanks for everything guys
