Default G14 Gas Stumbles on Takeoff

Anybody else have this problem? I have a street legal gas G14. When I have from traffic signal, the engine stumbles a little, and it takes a few seconds for it to get going, resulting in the cars behind me honking their horns. I am thinking about adding something like an excelerator pump or maybe adapting a fuel injector to give it a little shot of gas on start-up. Any ideas?

You might want to look if there is trash in the carb bowl or fuel system in general.Also look if the carb adjustment screw is at the 1 1/2 turns or so.Until I stretched out the tension spring the adjustment screw had vibrated out of adjustment resulting in poor engine performance.

Need more info, but wondering if starter brushes are causing the starter to stall at starting the engine? Dirty/loose ground, or weak battery as well!!?? "Street car" has to run like a top!!

"Street legal" has a special place in my heart!! As My "Spot", has thousands of miles of street use!!...

Thanks for the response. I have cleaned and adjusted the carb many times, and even replaced it with a new one. No change. It runs real well. It just is slow off of the line.

If it's got oversize tires, it needs Plowmans clutches or at least a UMAX spring in secondary clutch!!

If carb shaft bushing is in good shape, Please use the org carb. Much better!!

I agree. After no improvement with the replacement carb, I re-installed the original. I am thinking that I will use the aftermarket carb to experiment with ways to solve the problem. The clutch and drive belt are new. I striped the cart down to the frame last year, and totally rebuilt everything before doing a custom job on the body. I do have aftermarket 10 inch wheels, but I had the same issue with the stock wheels.

Then start looking at sealing the air filter box, it has to seal perfect or the motor runs lean, hence a hesatatation in throttle response !!

If you hit the throttle, does the motor crank immediately, or, does it hesitate? That's starter brushes!!

Thanks Mike, I will check it out, as the cart always smells like it is running lean. The air box is one thing I didn't replace. I just cleaned it up.
