I thought about getting switch to crank it from beside but didn't. I had someone crank it while I sprayed the starting fluid into the air cleaner. It fired off and sounded smooth but just for a second then it tried again and then not all even with ether while cranking. I tried priming the lp also while cranking and nothing. I had the carb off today all is free and open. I have the points just opening on TDC I even took a flashlight and looked. Both valves closed also. When I put it together I put the 1 on the cam gear with the 1 on the crank gear... I could not smell lpg in the #1 cyl today I even after cranking. When I prime it lp comes to the carb.. And why would it fire once on the fluid then not again... And it did not pop or backfire it sounded smooth. I am getting tired of cranking on the thing and I feel like I am wasting time like a fool and going no where with it.
