The balncer has the grooves machined in the outer ring. The new one looks just the same. I have tried the timing light all ready and the new balancer is dead on straight. This motor is dead quiet, no knocks or strange noises other than the gear noise when the oil warms up. It runs to good to internal, with all the moving parts in a converter, and the weight of a converter, it wouldn't take much to vibrate a small engine like this.
I have been drag racing for years and a truck mechanic for 15 years so finding problems is what I do, this on the other hand has me stumped! What I need is a set of heavy rollers like a chassis dyno, then I could find it!! Joe
