Is it firing at all. If it is blowing oil back out the air cleaner when you try to start on gas, you have the plug wires hooked wrong or the mag is 180 degrees out of time. Remember the rotation of the distributor button is COUNTER clockwise on these beasts. And if you have had the cover off the point chamber, it is easy to get the distributor 180 degrees out of time. There are only two lobes on the points cam, so there is 2:1 gearing between the cam and the dist rotor. Both of these situation will cause misfiring and blowing oil back out or the air cleaner. Don't ask how I know! Other than that, you have to check that gas is flowing and the carb is working, that the butterflys in the manifold are set correctly on the gas side, that the carb float is released in gas mode (Locked up to stop gas flow in diesel mode) and the the decompression valves are opening in gas mode. All this stuff is controlled by that one move of the starting switchover lever. Good Luck
