fuel starving

[Rick Thompson]

Hi guys. I want to thank Foul Plug , Norman and the others that gave me great advise on getting the right spark plug for my gamefisher 3HP engine. It starts better and runs longer.<br />I can now see that the engine dies out after running a while because it is starving for gas. It is a gravity feed system from the tank. I have tried taking the gas cap off to get air in the tank, but that did not help. <br />It seems that the fuel into the carb just doesn't keep up with the demand the engine has. I replaced all the gas hoses etc. I had to put a different shut offf valve on the moteor because the old one leaked a lot. It died out even with the old valve too.<br />Any suggestions?

Re: fuel starving

you don't want air in the gas tank. do u have a marine gas tank. does it have a primer bulb? that could be bad if u have one 2. cause i have a 30hp oil injected and the same problem happened. it would run for a little and die. so we took it to get it fixed and the primer bulb was bad<br />hope this works!!

Re: fuel starving

All fuel tanks require air to replace the fuel as it is used. That's why these tanks have a vent on them.If the vent is closed or otherwise plugged up, the engine will run for a while, the bulb will collapse.Within minutes, the engine will lose power and stall.<br />But you eliminated that possabilty,when you removed the gas cap,and found no inprovement.<br /><br />I would suspect the fuel pump,a clogged fuel filter,leaking fuel line,or debris caught in the jets of the carb.

Thompson:<br /><br />I have the same little motor. I have had nothing but problems and am now going to get rid of it on e-bay. A lot of people love those little sears motors.<br /><br />Mine does the same thing as yours. Last year I replaced the carb and that fixed the problem. But again this year, same problem.<br /><br />After it stalls I usually unscrew the fuel filter, dump it out and start it again. It runs for a while, and then when gas is given a lot it dies.<br /><br />I adjusted carb to lower idle figuring it was to rich a mixture, but again it dies.<br /><br />I am clueless and not going to give sears $157.00 for a little carb.<br /><br />I have no clues at all.
