shlitzcan 2 #1 Posted September 16, 2013 So I broke my fuel pump (aftermarket) and ordered a new one. Since I did so I figured I would put a new kit in the carb. The one i received was basic that replaced the old needle under the float and a gasket. I received the new fuel pump which is now all plastic with a metal arm?? and I have not had this 8 horse ever run like this. EVER> biggest issue is its pumping fuel right out the front of the carb. Can't get it to stop. I have taken the thing off several times to see what is going on and it appears that the float and needle are functioning properly when the carb is off. The float is not leaking and is dry inside, and it starts right up every time, but then it just suffocates with fuel. Also, I can't get the bowl to seal for the LIFE OF ME!!!! I have owned this horse for quite a few years, High compression rebuild port polish and has balls the size of Texas. But not so much right now. ' Help!! (i'm having withdrawls from driving this thing) 2 Share this post Link to post Share on other sites
AMC RULES 36,961 #2 Posted September 16, 2013 Sounds like maybe the float is out of adjustment. Share this post Link to post Share on other sites
953 nut 52,166 #3 Posted September 16, 2013 (edited) You may have put the float in upside down. Don't ask me how I would know this, please! Edited September 16, 2013 by 953 nut Share this post Link to post Share on other sites
shlitzcan 2 #4 Posted September 16, 2013 lol. The float sets level at close and the needle points up.... Share this post Link to post Share on other sites
daveoman1966 3,633 #5 Posted September 16, 2013 As to getting the bowl to seal... Maybe it isn't the seal(s). I had a similar problem, but it wasn't either seal. Come to find out, there was a pin-hole in the bottom of the bowl. I only discovered this when I ...for the last time... tried to seal it and held it up to a light.... SUPRISE. The tiniest of all pin holes shining thru... Had to get another bowl which solved the problem. Share this post Link to post Share on other sites
MalMac 1,328 #6 Posted September 16, 2013 I had the same problem as daveoman1966 on a 753. Come to find extremely tiny pin holes and spider cracks under the bolt that attached the bowl. Only way to see them was to hold the bowl up to a light in a dark room. Share this post Link to post Share on other sites
sorekiwi 761 #7 Posted September 16, 2013 (edited) The gasket at the top of the bowl should be above the fuel level, it really doesn't have to seal that well. Either the needle and seat aren't shutting off the fuel supply, or the float level is set too high, or the vent for the bowl is blocked.

shlitzcan 2 #8 Posted September 16, 2013 Thank you sorekiwi, the vent for the bowl, is that on the other side of the main fuel pin? Share this post Link to post Share on other sites

Was driving me nuts until I discovered the atmospheric vent was blocked..Its a vent hole in the top of the carb. body.....remove the float and you will be able to see it. Good luck!
