#30 Kohler carb seat threads
 

I replaced the carb on my CC149 with a new one. The only thing wrong with the old one was stripped threads on the needle seat. Like that when I bought it. Anyone know if there is a helicoil available for this application? I hate to toss the carb if it can be fixed.
Carb was on a Kohler K321.

I was thinking they were an odd thread, but I'll check. :bigthink:

OK. Thanks. (You said my last question was too easy !)

The big thing is, even if you can get a heli-coil, it's not going to be easy to install. Not much room to work, very small threads..... sucks but I'd probably just strip it out and toss the carb body, save the guts. May run across another carb that the bowl rusted off of but the body is good. Unless the throttle shaft is wore into the body, or it is cracked, you can bead blast the body and save them.

I'll still check the thread size when I am near a carb again. I don't have any here at home, they're at the shop...... :BlahBlah:

I thought about epoxying a new seat in. It would have to be a fuel resistant epoxy, maybe JB Weld. Might work for a while. Usually it's the tip of the needle that wears?
Slightly off topic: I have polished a leaking seat with a Q-tip in an electric drill. Q-tip dipped in auto rubbing compound. Worked the one time I tried it.

3/8 24...... that's the center main tube hole. the seat is an odd ball. never heard of one of those stripping out

none of the thread gauges (American or metric) that I have match it

Glad you checked Don. I was pretty sure it was odd ball, but I haven't been where I could measure.
