I can't get this 241 to run right.... Starts up pretty easy and will idle alright. Seems like turning my idle screws doesn't do a whole lot unless they're seated. Runs and idles, and when I give it some throttle, it revs up for a little bit, then starts to stumble. Putting it in gear absolutely kills it. Started it back up after it stalled, and it would slowly die out. As soon as it stalled, I pulled the top of the carb. Bowl was empty. So I disconnected the ignition, and turned it over to fill the bowl with the pump. Pumps fine, and the float closes the needle fine. Took some float measurements. top of the casting to the top of the float is right around 8 or 9 32nds. Top of the casting to the fuel level is around 24-25 32nds. What Am I doing wrong? New plugs, new points/condenser. Carb is fully rebuilt. Couldn't find any vac leaks with the brake-kleen... Plugs were a little black when I checked them. Seem like it's running too rich?? I'm stumped. Also..I definitely don't know carbs that well. So that doesn't help.
