I bolted the new carburetor on and the engine started right up first pull without the usual shot of ether. I did have some trouble with it under load. The motor didn't seem to have as much power when I got into heavy snow. Pulled the load screw out and found a small piece of what looked like metal shaving in the opening of the brass tip. Removed that and gave it a try. The motor runs like new now.. Thanks for getting this carburetor to me so promptly. We've gotten 36" of snow so far here this month.
