THATS a good option...... I may do that !!!!!

........ does this sound correct..... i put all back together, it leaked BUT, just for a while after i added gas, like maybe until the float set the needle valve, now it seems to not leak ...... perhaps i just needed more gas to push the float up ?

thx tom

Which carb kit did you use? That engine should use 491588 and you MUST install the needle seat correctly. Here is the procedure I recommend and use. Rebuild more carbs each year than I care to count and less than 10% need to have the carb replaced.

Needle and seat replacement.

Remove the carb, and then remove the float bowl. Check the float bowl jet (which is the bowl screw) and make sure the jets both horizontal and vertical are clean and open. Tip the carb upside down and remove the float pin and float with needle attached. Look in the float needle passage and you should see the red float seat at the bottom of the passage. This is where a #5 crotchet hook would come in handy as you need to remove this seat. If you have no hook, but compressed air, you can blow through the fuel inlet and try to pop the seat out. Put your thumb over the passage to prevent the seat from flying who knows where. No air or hook try bending a stiff paper clip to dig the seat out.

I would either give the carb a good 24 hour soaking or have it ultrasonically cleaned at this time.

With the seat out clean the passage way with carb cleaner. Now you must find a drill bit slightly smaller than the passage way, to be used to press in the new seat. Apply a very, very small amount of a very light lube to the new seat. 3-1 oil or lighter, to help seat it better. Carefully insert the new seat in the passage way with the rings on the seat down toward the carb body. Slowly and carefully force the seat down with the back end of the drill bit. Once it is seated, check to see that it did not flip and the rings are up. *Next check to make sure that the float does not have any liquid in it. *If it does, replace. *If everything looks correct, attach the new needle to the float and install with the float pin centered. It everything is correct, the float should seat level to the carb body, when looking at it upside down. If everything looks good reattach the float bowl, making sure that both the bowl gasket and the nut gasket seal properly. Reinstall on the engine and test unit. Remember to have patience and take your time. Good luck, but I don't think you'll need it.

PS: *On the side of some Tecumseh carbs you will find a plastic cover. *Under this cover will be an idle jet. *Remove it and check to see that the jet is open both horizontally and vertically. *You should be able to push the old float needle wire through the vertical opening.

While cleaning a carb today I realized that I gave you the wrong kit part number. Should be 398188. Sorry about that, it was a long day.

Thanks for all that info !!!! As i said i did the deed already, thought all went well :) but when i hooked gas line up (had a small amount in line) it started leaking out of the bulb again. I got pissed , but then i thought the float has to push the needle down and cut off flow, so i added gas to the tank....... no leaky anymore soooooooo ???? i think i fixed it :)
i started it and ran , not more leaks , now i have to cut the yard !!!!!!!!!!!

Thanks again to all of you who had knowledge and helped !!!!
