I got the 70cc kit in and running with the Arreche/Amal carb.
I had to cut the base off of my original intake manifold and use it as a spacer to get more clearance between the carb and the block. The carb is still a little slanted but it works.
I also flipped the piston back to the way it is supposed to be installed (slots on intake side). Does anyone know which screws do what on this carb? I assume that 1 is for idle control and 1 for mixture but which is which? I'll search the net for this info but I thought this may be quicker.
