Hi, a neighbor has a JD Lx 277 with a 17hp Law FH500V. It was leaking oil between the crankcase halves. Removed engine opened up and found the gasket had been sucked inside.sucked inside. Waiting for gasket and seal. Finally got back to work on it and it and the workbench had collapsed and the cam had fallen out. So using the Law service manual, removed the push rods and replaced the cam with the timing cards lined up. Reassembled, and adjusted the valves ASPER manual and checked the coils and flywheel everything OK. Tried to start and it's hard to start and runs like crap, backfires thru the carb and won't some up to speed. Thought timing was off, so torn the engine apart again and nope, the marks were right on, tried it again still the same results. What am I missing? Any help would be greatly appreciated. Thanks
