Ok, I got the fuel pump on, the carb was clogged and I took that off and cleaned it, the float looks like crap, but at this point, that's the only float I have. I cleaned it up as well as I could, put it together and when I tried to start it, I get a pretty impressive backfire every 10 pulls or so. It won't start.<br />To get the carb off, I had to remove the clamp that connects to the little rubber roller camshaft. When I put it back on, I'm sure I've got the adjustment wrong. How do I adjust that roller and cam so that I know it's aligned correctly. As always, thanks in advance.
