The carb is a YF 938 SD. One of the screw holes in the float section is stripped out. This is where the top section, with the choke, screws to the float section. I have tried a new screw which did not help. Any thoughts or help much appreciated.
Hi btnsc, you gotta real name? Phonetically I'm stuck on pronunciation.. Friends call me Muley.. easy to say huh?? I had good results on a YS637 (even with a crack in the hole to the ext) by cleaning the hole and I mean clean of any residue. Filled the hole with a very viscuous JB weld mix and cured for days, ran a tap 6-32??? Muley..

Hey Muley, names Bill. That's a good idea. Ole-green is a civilianized M38A1. Had her since 1963. Sad to say she has been in retirement for a few years. Took her out of the barn and brought her home for some much needed attention. Thanks for the tip.
I use them quite a bit. Especially on YF's where the choke cable bracket attaches. Gauge carefully the solid metal around the screw hole, with the realization that the drill bit will be larger than the hole and the tap will apply stress to that which remains after drilling. I would hate to hear that the wall of the bowl was cracked.
I have had to repair both corners at times. Some folks over-tighten and destroy the threads. A fall-off of vacuum and possible fuel leakage at that point. I and reticent to suggest this but have you tired using just the screw with no washer?
