I'd suggest carefully unscrewing the jets and trying to actually blow through them, or hold them up to the light and look for light. Make sure they're really really clean. Clean the float needle and jet as well.

bump

Update: A couple of my jets were clogged, and one of my float needles was completely stuck in the cylinder. I cleaned the whole thing with carb cleaner and then soaked it in fresh gasoline, about to re-assemble it tonight, I'm hoping she'll fire now.

Ok, problem. I cleaned the carbs. Now I can start it without starting fluid, but now gas is gushing out of the left side overflow. I figured maybe a float was sticking, I opened it up, all the floats can move up and down freely. None of them appear to be stuck. If fuel is just pouring out of the overflow, is that the only thing that it could be? Need some advice.

They aren't set to the right height

gunk is clogging the hole preventing it from closing all the way

What exactly do you mean, when you say they are not set to the right height? Do you mean the floats? I dont understand that. Also, if you are talking about the hole where the float needle is, I cleaned them properly, and there is no obvious gunk in them.

Floats must be set to the proper height within the floatbowl. If they are too high, they will allow too much gas into the float bowl, which will exit through the overflow. Your repair manual should have the procedure for setting the floats properly.

I don't have a manual, may pick one up tomorrow. You say the floats have to be set to the right height, maybe I'm missing something. The floats are hinged. You have the float pin sitting in the groove, then a screw there so the pin can't come out of the groove. There is no way to adjust the height that I can see. It swings up and down freely with the flow of gas. Now, there is a thin peice of plastic connecting the two "drums" on the float, that when there is no gas in the bowl, it prevents the float from dropping all the way down.

I don't know, it's only over flowing on the left-side of the carb, the right-side seems fine. All of the floats are set the same way. I'll give it another crack tomorrow and check the float needles again. If you guys can think of anything else that could be causing the gas to pour out of the overflow let me know.

Thanks for the help.

you bend the part the needle attaches to.

Ohhh, I see what you're saying. That makes sense now, thanks. I'll give it a try tomorrow.
