Hi guys, I have a 41 H that has just been bored out to .060 over with EGGE pistons and rings, a new head with new, guides, seats, locks and valves. Real good compression, valves set at .015, timing is right on, new carb from Branson set at 1 1/4 turns on idle, 3/4 on load, mag is brand new with points set at .015, nice bright blue spark. My problem is that I can't keep it running! It will start up and run at slow idle and when I give it throttle it spits and sputters like it is either out of time (which it is not) or not getting enough fuel. The only thing I have not checked is the governor/weights. Could this be causing those symptoms? Any ideas would help at this point. Thanks in advance.*

Be sure and check the intake manifold, gasket, and the mounting surfaces for air leaks.

if you try and run up the speed at the carb will it? You should sorta be able to see the linkage try and move when you run it from the throttle, but if you try at the carb that may give you some more insight. When it is running, try spraying a little brake cleaner around the manifold, if you have leaks you will hear it in the motor. What does the sediment bowl look like? I have had the cork gasket and screen break down and suck pieces through not letting it run until the suction is clear, then they would run great again till another chuck pulled through.

Hope that helps cause it sounds like it outta be quite a running little H, might make the B's run scared lol

Thank you for the replies. To answer some questions you posted; the manifold gasket, gasket surfaces, studs, and nuts were all new or like new bright and shiny. The manifold itself is the original. The sediment bowl has completely new cork and screen....and is completely unobstructed. The gas tank was completely stripped and relined. I took the governor shaft assy out and found quite a bit of "slop" in the weights and pins. The timing marks were right on. The left cage bearing is also questionable as it is not as tight as it should be on the pressed on bearing cup (race). Could the backlash on the bevel gear be a factor? I know this probably won't cause my problem but it could be be part of a bigger problem that is. BTW my fuel is new, so there is no issues there. Thanks again!!

The other thing that needs mentioning here is the air filter. Is it the factory oil filled air filter or an aftermarket pleated filter? This will have a huge effect on carb settings.

If the inner part of the filter hasn't been cleaned, you can use kerosene to help get the gunk and dirt out.
