Tecumseh 6.0 hp motor only runs when primer bulb is held in
Original Message Jun 8, 2006 4:05 pm

Hi i have an tecumseh 6 hp motor and this year i took it out to mow my lawn and i got it about half done ant the mower cut out i thought it might have been out of gas but the gas was fine.
i knowsed that it would only go while continue ous pushing of the primer bulb or just holding it in.So where i my self am a pretty good handy man i removed the carb to check it anc clean it during the removal process the i nodiced the air filter had a hole in it and might have sucked in some dirt and clogged up the carb. Once i cleaned the carb i put it back on and i tried to start it but would only run for a few seconds and cut out but if i hold in the primer bulb the mower and it runs fine.

What could the problem be and how could i fix it?

Check this out.When you reinstalled the bowl on the bottom of the carb you may not have put it back correctly thereby its not letting the float come down enough to let gas in.You need to reinstall it in a manner that when the bowl is put back the float can still come to the point where the fuel that fills up the bowl will raise the float and then shuts off the gas until the level in the bowl drops again and lets it take in more gas.In other words the bowl itself has a shape in the bottom which can only be correctly installed in one direction.Hope this helps you.Best of luck.

check your lines to and from the primer.....a crack or air leak here would allow it to suck air and create a vacuum leak, or possibly the diaphram in the primer bulb has gone south. try replacing the primer bulb and while your doing that go ahead and replace the primer bulb lines

i had the exact same problem on a leaf blower and what i mentioned above turned out to be the problem
