Of course I did exactly that. After a few miles the wiggle broke the oil pump shaft and the engine died instantly (no Dizzy!)

Just something to look out for not in the manual.

That got me to thinking, so I double-checked the distributor and oil pump. My distributor will only mate with the oil pump shaft one way, so I guess I had it right.

Thanks for the tip!
