Hey all,
IDK what section to put this in, but I am working on a little yard tractor, 18 hp sears with a 2cyl. Briggs.
I have been having flooding issues after dragging the mower out from 3 year storage I forgot to drain the fuel, but I used plenty of additive, and so the carb was actually quite clean.
So, I finally got a rebuild kit, and it comes with a new needle and seat. according to the manual, the seat needs to be flush with the body, and so that is part of my issue, old one is deeper, could very well be why its flooding.
So, I follow manual instructions roughly, it says I need to use a 1/4 inch self tapping bolt as a puller.
So I find a 1/4 x 1 inch self tapping bolt, thread a nut onto it, and use a brass compression fitting to fit over the hole to still allow the seat to come up, but to spread out the force and not hurt the carb body. The manual wants a little spacer from a fuel tank, but I cant find one on any of the parts engines.
I am only running the bolt in about 1/4 inch before I run out of threads, and it turns very tight.
after tightening down the nut and pulling the bolt out of the seat a few times, I gave up. I hosed it down in penetrating oil and put it in the freezer, thinking that expanding and contracting at different rates, the penetrating oil might soak in.
Do I need a longer bolt, and if so, do I need to be threading it in till it bottoms out in the seat? I am scared it will hurt the carb if I do this.
Worse case, is this a very common issue that a seasoned briggs shop should be able to easily handle? I might be better off hiring this one done.
