Customer Question

Hi J.R. I have a tiller with 8 hp briggs horizontil with gravity feed updraft carb. mice ate wires so i converted it to pointless ign. float needle stuck and carb was in rough shape so installed a new one. starts fine then after about 30 seconds rpm increases then it dies. i set both needle valves to 2 1/2 turns. I'm bewildered it will restart then repeats symptoms. Thanks for any help, ***** *****

Go back and check the fuel line at the carburetor and the needle valve passage from the fule line. I think the fuel is restricted, and the flow into the bowl is not enough for engine to continue.

I wI will check again, I did replace the fuel line when I replaced carb.

One small piece of debris in the needle valve passage is all it takes!
