Yes, but I am still breaking in the engine and it idles pretty rough.

The firewall is doubled 1/8-inch plywood. I seemed to be crushing in the small flat washers I had used to shim for right thrust - may have limited tightness. Replaced washers with thin shim of aluminum all along left side of mount, allowed more torque/tightness.

I put a small amount of blue loctite on each once also... if they don't hold now I'll be surprised!

Thanks all for the advice.
