Engine loses power

[careyo63]

Filled it with gas and no difference. It did have 3.5 gals so i don't think that was it. It has a brand new gas tank but I used the old cap. I'll try a different cap and then start backtracking thru the fuel shut off (also new) and then the carb.

Try starting fluid or Either since it's gas. How I found out quick it was a fuel problem. Not on my Diesel though

Is the fuel tank full?

I don't have experience with an 8n but my old Farmall has gravity feed from the gas tank and if the gas is low it will act like that. More than once I have backed up a hill when it stalled.I first though that you may have a restriction in the fuel line but the fact that it backed up the hill pretty well answers that question.

I checked the floats and they looked fine. Throttle linkage and governor linkage looked fine. Put it back together and went to drive it around with similar results, any slight uphill causes it to stutter and cough and then die. BUT! when it died, I restarted at idle and then throttled up halfway and backed down to level ground. No problems. Got curious and backed up a much steeper hill and it had full power all the way up! Did it 3 more times with full power each time. I could hear the governor apply power as it climbed so I don't think the governor is the problem anymore and it likely isn't ignition so I am left with carb or fuel? Any idea what to check to find out why I have power uphill in reverse and not nose first? It has me baffled.

Make sure the points and condenser screws are really tight. Back in the 70's I had a chevy belaire that I would tune up myself. AC Delco came out with the "uniset" which combined points and condenser on one metal plate. After i particular tune up when I couldn't locate a uniset, I swapped back to the original set up and forgot to tighten the condenser screw properly. Once the car bucked or bounced it set in motion a constant bucking that was caused by the condenser, now suspended only by the wire to bounce in a rhythmic fashion only touching ground occasionally. I don't want to be reminded of everything I went through till I pulled that distributer cap back off !!

I think I've solved it. Since uphill backwards was full power that would eliminate the tank and fuel line. Same with the carb fuel filter. Checked the air intake for obstructions and nothing. Ordered new, better quality, carb and installed. Set the needle adjustments exactly as the FO-4 says. Started it and idle was good, backed power needle a half turn and bingo! Just ran it for 10 minutes and it ran great uphill, downhill, and under load. I'll put some time on it tomorrow just to nmake sure it wasn't a fluke but I at least know where to start if it does it again.Thanks for the help and suggestions!
