B&S timing

Hi, I keep throwing off the timing on my B&S 5hp snowblower model 130212-0764 built in 77. I recently did a tune-up on it to try to get it to start easier without using quickstart. Tune up included new condenser and breaker points, head gasket, valves reseated and clearances checked. I ran it for a while then tried the auger and it stalled, could not start it again so I checked the spark and found it not very good. Sooooo I pulled the flywheel again and found the key damaged and replaced it. I ran it again and adjusted the idle and top no load speed then tested it with very light snow (2cm). It worked ok but when I shut it off I couldn't restart it again. I checked the spark again with an inline tester and it was weak again. I'm thinking maybe I didn't tighten the flywheel nut tight enough. Any thoughts or ideas? I didn't hit anything with the auger to damage the key.

should be 55ft. pounds, make sure the key, the slot is clean of any oil, rust, and trash.

Another thing, I'd forget the points and condenser and just replace the coil. New coils come with solid-state ignition modules that don't rely on moving parts (poinst) to give correct timing. They are much more accurate and trouble-free.

Also, along with a torque wrench, a Briggs clutch wrench, part# 19244, would be of great help to torque such down properly.
