| To me any time a engine backfires it's probably a timing or dist./ignition related problem or a outside change a carb. problem. First I'd check the points gap, cap, rotor, wires, Then, I put a dwell meter on it see if the dwell is within limits (means you got the points gap correct) then, I'd also put the NO.1 Cylinder at TDC with the rotor button pointing at #1 plug wire. Now look see how close the rotor aligns up with the #1 wire on the cap. Should be just before as your engine should be timed some where about 8 degrees before top dead center. ( timing chain could of slipped a tooth, if so the dist. will be off when you have it at TDC, not likely since the engine was recently rebuilt) This will give you a idea if the engine is close to being timed. As for the turning backwards that is a rare instantanious moment that usually occurs just as the engine dies, Once you hit the start it cranks it the normal direction, if the timing is off by what ever problem then that's to me is where you get the backfire. As for the oil leak, you are just going to have to get it running and find out where it's leaking if you can't see where it's coming from. Another posibility is that the dist clamp bracket bolt is loose alowing the oil to leak or the O-ring is bad as Stanley suggested. Their is a oil sending unit at the back of the block. Usually it is a elect signal, but., if you have a direct pressure gauge then this could be a the source of your oil leak. As for common on FEs to me it's not, Any engine that's out of time, ignition problem, or carb. problem will backfire through the carb. Hope this helps, post your findings in detail, I sure you will get some more responses with more actuate systoms. |
