I have a generac 992 propane motor converted to carb with stock generac carb with choke. I have it on a golf cart. It runs and in neutral idles and revs high but when I put it in gear and mash the gas it bogs down. It doesnt rev very high before it bogs down.I can't seem to figure it out. Yes I'm a new here but pretty mechanically incline. Thanks in advance!
