I have a 6.5 horse Tecumseh motor with a carb 790120. The mower sat for a couple of years and now I have it. Rebuilt the carb (gaskets and cleaning jets) also replaced the primer bulb (the one with the hole in it). Problem is now the mower drips fuel out of the primer bulb, I can start it and it runs fine except for the fuel coming our of the bulb. Can I replace this bulb, which is new with the type w/o the hole? Is something wrong with the float?

Like I mentioned the carb was taken off, cleaned with carb cleaner, blown out and re assembled with new gaskets, float bowl ring. Any help would be appreciated.

Probably when you blew out the carb, you blew out the seat for the inlet needle, remove the carb, remove the float, check to see the seat is in place. Have a good one. Geo

Here is a link to your carb which shows the needle seat that Geo mentioned.

the seat for the inlet needle is the very small red ring that came with the carb kit, I replaed the ring the same way it came out with the "ridge" end facing up, still leaks fuel Float has no holes and sits level in the carb bowl.
Air filer housing is tight, air filer is new and sits within the air filer housing.

The "ridge" facing up is when the carb is in it's installed position. Have a good one. Geo

Are you sure the needle is not sticking? When the bowl is empty the float/needle drop, sometimes the needle will drop to far and get stuck. I usually twist a piece of steel wool in the hole of the needle to polish it up before putting in the seat.

The carb was put back together with the seal facing up in the installed position of the carb. I will take it back apart and try the steel wool. I did replace the needle as it came with the new carb kit. Thanks

Wether the carb is on or off the engine, the ridge side of the seat always goes in first. Make sure the seat is seated all the way in.

Why is the title of this thread "Briggs carb problem" , but when we're in the thread it's talking about a Tecumseh carburetor?
