Could backfiring cause this?

Randy I don't see any way this motor ran fine any time, wrong flywheel also, no weight to remove either, if the cranks OK then get the correct wheel @ remove the weight like Mike stated and you should be good. I think

ok randy,the bearings are correct and is narrowed ,the x indicates .001 extre clearance ,the h is a high perf bearing.those are good bearings and i use them a lot.as already stated the balancer&flywheel is not correct for internally balanced engine.

The shop says they are going to rebalance the crank, I have a new flywheel coming also new bearings & will reassemble myself. He showed me the balance being off so I will have him show me the balance again when he's done. He says the crank is off by about 1 1/2 oz.

Everything is there so he could determine the weight for the Bob weights. As far as the balancer I will see what I can do. I really am sick of spending money on people's mistakes so I will look for one in my pile of parts. I can't believe I have to stand over someone's shoulder to make sure that what I paid for actually gets done!!!

This engine is so screwy, as far as I know from personal experience this crank and this balancer ran fine on the dyno. The flywheel is suspect. If everything gets checked AGAIN in front of me so I can see it for myself, and I reassemble it with the correct bearings at proper clearances it should run shouldn't it? Apparently the builder in Omaha was a drunk monkey or something. I will not be sending him a Christmas card!!
PM me if you like.
