Steve, look for a turnbuckle linkage on the carburetor. If it is there, a knurled tube with a locknut on each end is the fuel mixture adjustment. After you have removed and cleaned the vaporizer like others have said, and replaced the diaphragm and get it running, you can adjust the fuel mixture with the turnbuckle. Set for smoothest idle. This raw propane smell tells me the there is a hole in the diaphragm. It will be so tiny as to be hard to see. take the diaphragm in your hands and stretch it really tight over a light. If you see light, you have a hole. When everything is all put back together, remove the flexible hose that goes from the vaporizer to the carburetor. With gas valve on and key on, there should be NO GAS come through this hose. The vaporizer regulator is set to atmospheric pressure. It takes the vacuum from the engine cranking over to move the gas through the carburetor and in to the engine. If you have gas coming through the flexible hose with it disconnected fro the carburetor, DO NOT run the machine in this condition. You will have a crankcase explosion if you do. All this is experienced first hand by ME. I was trained by an LP Gas dealer. I kept trucks and farm machinery running as well as fork lifts at Holley Carburetor Plant. Email me if you have any questions. Steve in Bruce Ms.
