FasTrak 48 with 21HP Koehler

[Decker]

Gas is good. I took off the carb and blew it out as best I could without totally disassembling it. I do not have a wonderful record on getting them back together in the best of shape. I am thinking to just put it back on and see what the scoop is. Is there anything I should try before putting it back on?

that carb is fairly simple to take apart, apart from the fact you need a SKINNY, 1/2" wrench to take off the solenoid.

OK. So I took it apart and blew it out and reassembled it. In the process of reinstalling it I found a spring that is about 1/2” round by 1/2” high. I suspect it belongs in the fuel pump and went flying when I accidentally blew the back off the other day. If this is the case, where does it go, between the internal plastic and the rubber bladder flap?

post a picture of it.

The pump. When reassembling, should it be glued together?

 

[Decker]

Now I see how it should be. Spring goes in the center of the piece with one fuel port.

Sorry, to tell you the truth I’ve never had one apart, but I would probably glue it together as they are normally a non repairable part.

I glued it. Reinstalled (air filter off). Tested....no joy on normal start attempt. Added starter fluid....bingo. It runs but is rough. Repeated this sequence with the same results a couple of times So there is still something out of whack. If nothing else I can get it running to put on the trailer to take it to the shop.

might need actual caburetor cleaner to clean the carb out.
