I indicated the problem bad crank till I got it all but dead true. Tack welded one end of the crankpin for the rod so little chance of warpage from heat. The other end was still tight but just in case of movement later, I put one small tack weld on that end also.

In the process of all this, I inspected the bearings and one of them has a chipped ball bearing. Are these a standard size between all of the Echo small engines? I'd like to replace both ends since I have them off. I asked all my local dealers but they don't stock them cause they never go that deep into repairs. Isn't that what a dealer/service shop was supposed to do?
Oh well, I'll have to get a magnifying glass out to read the numbers though.
Anybody have the numbers already to save me the agony?

Thanks

John
