New here, so bear with me! Bought a YS-637 knock-off carb from AJP for a mere $75, eBay, NIB, but was warned that He had a problem with idling. No blame, my bad, I took a chance! Whatever, has anyone had any experience with this unit, and if successful, what was needed to make it work.
As an aside, I have NO idea who made it, but it looks really good. Hoping, Bill p.s. My jeep and history are at www.bill-capes.com/insanity |

AJP probably bought it from Brent Mullins jeep Parts. He was selling these also. Make sure the metering rod jet has the correct opening. Drill size is #41. I got 3 working used original YS-637S carbs and there is not much to them except float setting 1/4 of an inch and idle mixture screw. Also make sure diaphrams are not leaking. Good luck.

OMG - I got it to work!
#1 - Float level, WAY off, shutting off fuel, (low level in bowl) #2 - Upper hole in Bleeder tube (Item RS in manual) partially plugged with small residue from drilling it during manufacturing process. #3 - Bleeder tube not tightened, possible partial air leak Which one did the most good? Darned if I know Thanks for all the help, gave me the impetus to open it up! |

Glad you got it going. They are a cool carb for they where the first type to be fully waterproof. Easy to work on as you found out.
