After a third rebuild and after a stealthy overnight lavage in the wife's ultrasound, it still wouldn't work properly. So I swapped the thing with an aftermarket carb. The TB20CS started up and runs, but the new carb leaks fuel... of course. <plaintive sigh>

I need a Momentary-ON Detent Trigger Switch. model no: FD04-2116. I cannot find this switch of an equivalent-compatible switch. The parts diagram for the tool doesn't list this part. A link to this part, or its equivalent-compatible, would be greatly appreciated.

My Troy-Bilt TB20CS worked fine in the Fall before I packed it away dry. Smash-cut to Summer 2021. After topping off the tank with nummies and priming, I find the trimmer behaves consistently as follows: First pull, full choke: a brief catch. Second pull, half-choke: the engine surges then dies. I figure this is a symptom of fuel starvation, so I presume either/both a dirty carb and/or fuel line issue. I remove and disassemble the carb, blow carb-cleaner thru its orifices, and install a new diaphragm; I also replace the lines. After reassembly I get no change. I suppose I could mess with the "low" needle, but this seems unlikely. I exhausted my t'shooting skills and I'm officially stumped. Recommendations? Suggestions?

Yet another "Nailer--No Fire" post... My D51844 Type 1 was blowing air out of the exhaust when the trigger is depressed (with no fire). I fixed that problem by replacing #6 and #10 o-rings. Now the problem is, there's a quick "pop" sound with each trigger press but with no blow-by. The nailer still will not fire. I presume either the 1) piston driver is stuck, but I have no idea how to t'shoot that idea; and/or 2) another seal needs to be replaced. Anyone familiar with this specific symptom?
