Carb sizing
Had some issued with seizing in the past. AF24 with a 50mm bbk mini stroke crank 19mm carb ect. Could my carb be too small ? Want to start working on it again. Last time i thought i might have had an air leak at the oil pump shaft cause it was loose. Been running premix 32:1 felt like it was tuned pretty rich but seem to have killed it anyways. Thats why im thinking maybe this carb is too small?

Re: Carb sizing
Did you do plug chops with it, did you have a cylinder head temp gauge? Lots of people run 19mm carbs on 48mm kits on stuff so can't see being that much too small on a 50mm. I would think it would be fine as long as you can jet the idle pilot and main jet accordingly.
