Here are the preliminary results….drum roll…I took the carb off and pulled it apart…very clean looking, but I removed all the jets and cleaned them with carb cleaner, blew them all with 60 psi….all openings in the carb were cleaned with carb cleaner and blown out as well…float floated, so no issue there…As I mentioned before, I’m not a carb guy and while we can never be 100% sure, I’m 99.9% sure that this carb is clean…installed the carb, threw in a little starting fluid to get her going and of course, she fired right up…idled fine for about 40 seconds then began to spit and sputter, but not nearly as bad as before…she didn’t die…I began to adjust the volume control by first turning it all of the way in, then backing it out 4 turns, the bypass screw all the way in, the back out 2.5 turns. Idle was still rough, so I backed the bypass screw out 4 more turns and the volume control out 2 more turns….idle was better and she didn’t die…I let it run for about 15 minutes at idle, giving it some gas every few minutes….engine was good and hot…so, better than before, but here’s what I discovered…intake was still ice cold…heat riser on 3 and 4 cylinder was a little warm, but far from hot….heat riser on the 1 and 2 cylinder was very warm, but not extremely hot….main body of the intake was cold….so, that’s where I’m at…it idles (not ideally, but it idles)…so, what I’m thinking is that my vintage Abath exhaust may need replacing (possibly)….exhaust is still very, very rich smiling, I reek of carbon monoxide…lol garage is full of it and I have to open the door to breath….You can see in the pic above the exhaust residue on my leg, still very rich. I’m still confident that it’s running too rich, how to adjust that, I don’t know….I’m also confident that fuel has made its way into the case…I changed the oil about 200 miles ago and it’s already very thin….and a bit fuller than it should be.
