Is there any sort of replacement carb for the Marvel Schebler VH 12 on a Wisconsin AKS? This is on a ridemaster. I think the original carb was worked on and has loose butterfly throttle and a few other issues. It had a valve job prior and has not been run much since. The engine surges and after fires out the exhaust. The mag gives great spark when turned slowly by hand. I adjusted the governor per the book but there's a little slop in the linkage in on the carb. If I hold the linkage steady it stops surging but still after fires and quite often stalls. Its getting plenty of fuel. I'm not sure what's going on and may need to eliminate issues one at a time to get it running smoothly. I thought intermittent spark for the after firing but the mag seems good unless it's breaking down at engine speed. I'll be pulling the engine to check the mag to engine timing via the timing window behind the flywheel shroud.
I see they have the mag, cover, points, condenser, plug and wire on ebay if it ends up being something mag or electrical related.
Any ideas or thoughts is appreciated.
