Notice: I get wordy when I try to explain things. It was suggested by someone on a previous posting that I put this warning on the front of the posting instead of at the bottom, so they don't waste their time. They may have been joking, but it is difficult to tell over the net, however if everyone can see how long the posting is and they are not interested they can quit reading at any time. I am trying to pay back the people that help to educate me and hope I can do the same for others. I feel I take quite a bit of time to make sure my postings are as accurate, punctually and spelling correct as I can. I checked things out today. I did a compression test cold and then took it out to warm it up enough to make it start misfiring. That was difficult as without a deck or the blower on it, it took quite awhile to get it warm. I pulled one of the plug wires after I ran it long enough to get it to start missing and the first one I pulled didn't make any difference, so I concluded that was the problem cylinder. I did the compression test again and both readings were lower than the first, but they were equal both times. The valve clearance on both intake and both exhaust valves was near zero. I got the valves and seats cleaned up and then lapped them after I shortened the stems enough to get a little clearance. I got the clearances fixed and am ready to reassemble except for a little problem that I caused. I was cleaning the exhaust manifold mounting bolt tapped holes and as I was backing the tap out on the second hole the tap snapped off. I guess I need to find out if the fleet store has a tap extractor or else I will give my son another experience with his new wire welder to try to weld a nut on the tap. Thanks to all who suggested that the valve clearance might be the problem instead of an electrical issue as I thought it was.

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
