Are you 100% sure you got the cam and crank gear timed right?????? Very very common problem with small engines and I have opened up a good many that the guy got the wrong. Still remember back when I was in high school my dads boss who had a doctors degree but did not know engine got that wrong on a 5HP B/S engine Took me maybe 30 minutes to have it running

that part of the motor came from factory. I'm assuming it is correct

Is it an over head valve engine or a valve in block?? If it has the valves in head make sure the valves are set at the correct torque or you will have odd problems

Some times-on older Briggs engines, and Tecumseh, too, the boss where the can gear fits into the block, will be sloppy, and even though you get it meshed to the correct gear, i have seen a few that would allow the cam gear to fall out of "time" with the crank-shaft when reassembling the engine. I solved one of those problems by making a loop from 1/4 inch masking tape, to hold the cam in mesh with the crankshaft, until you get it assembled.The mashed up tape doesn't seem to harm the operation.
