Hi bigted, I haven't been using the G4 cams because all the ones I have don't have the ramp, just a square stop. My problem with this design is it is so hit and miss, they work,they don't work, they jamb, they don't jamb, you just keep your fingers crossed and hope like hell. Pull it back too hard and it jambs and then it is pull the carb apart to release it. Not one of Victas finest moments in design work. I ground the ramp out of one yesterday, fitted a 6mm bolt as a stop and fitted a kill switch on the cowl, works like a kill switch and carby should now
