After a no start condition with no fuel getting to the carburetor, I started looking at old forum questions. Kohler mechanical pumps were pricey and aftermarket parts are iffy. Digger posted a fuel pump from Amazon that he had used. I looked at it and it was $100. I found this one for $25 and it had pretty good reviews. At any rate, I installed it on the firewall and added an in-line fuse. Fired up instantly and it should also help cold weather starting. Time will tell if it lasts but I am initially very happy!
