Joe Sullivan 18 #1 Posted January 20, 2017 Hello y'all. I'm new here, and figured I'd try it out! Last summer I removed my fuel pump from my wheel horse C-85... (8 Horse Kohler). Only took it off to try on another tractor that was having issues... Went to put it back on this winter to plow my driveway... Well it's back on correctly with the gasket. When I crank it over, it fills the filter about a fifth of the way, not enough to get gas through to the carb... And it doesn't fire. If I squirt some gas into the carb, it will fire up good for about 10-15 seconds until the gas I squirted in is burned up, then stalls. I've replaced the filter, replaced the lines, I guess it sounds like the pump, but I just can't bring myself to believe it though since I've had no issues at all until just now. If anyone has any thoughts, that would be great! Thanks! Share this post Link to post Share on other sites

953 nut 54,343 #3 Posted January 20, 2017 Try removing the fuel line from the inlet of the fuel pump and lower it until fuel runs out, then connect it to the pump, they are not too good at pumping the air out of a fuel line. 4 Share this post Link to post Share on other sites
KC9KAS 4,741 #5 Posted January 20, 2017 Others have made suggestions with the fuel line to the pump, but I would also disconnect the line on the outlet side to be sure it is pumping fuel. Be sure to aim it away from the points/plug/coil.....I have caught things on fire before! And, to Share this post Link to post Share on other sites

Pollack Pete 2,273 #9 Posted January 20, 2017 That's the very reason I don't like taking parts off a runner to try to diagnose a problem on a non-runner.Usually end up with problems on both machines.I hate to " rob Peter to pay Paul".Of course,that's why I have cabinets and boxes of tractor parts.When I need a part,I usually buy in multiples.Works for me. 2 Share this post Link to post Share on other sites

WHX?? 48,035 #11 Posted January 20, 2017 Some must die so others may live TDF?!?!? Might have just got some gunk in the check valves of the pump or they are not seating..... might want to try and flush that out. 2 Share this post Link to post Share on other sites
Joe Sullivan 18 #12 Posted January 21, 2017 Wow, thank you guys so much!!! I will try to remove the outlet first to see if it is pumping fuel, then I'll go from there... I'm glad I tried out this site, y'all are real nice! I really appreciate the responses, thanks! And I am sure the lever is on the correct side of the cam, I checked that to be sure, but the pump won't fit in the other way. 1 Share this post Link to post Share on other sites
Joe Sullivan 18 #13 Posted January 21, 2017 Okay, so the pump is functioning properly, when I unhook the outlet line from the carb, gas squirts out when I crank it, but when I hook it back up to the carb, nothing... I tried taking the valve out and blowing through the carb through the hole where the valve goes, and can't blow through it at all, I assume that's why the it won't start...? No gas is getting into the carb, but it's getting to the carb. 1 Share this post Link to post Share on other sites

Joe Sullivan 18 #17 Posted January 22, 2017 Thank you all for your help! If anyone is getting gas to their carb, but not into their carb, you can bet it's a stuck needle valve. Hope that can help other people too! 5 Share this post Link to post Share on other sites

I replaced the carb on my B-100 with one from my C-121 with blown engine, until I get a chance to tear into it. So I robbed Peter to pay Paul as we mentioned. 1 Share this post Link to post Share on other sites
