Ford 8n - Must Have Choke Out

[NELS1]

**** Weather, fuel, temperature all have an affect on engines. ADJUST away, make the engine run right . If your adjusting to overcome some other problem thats another story but when your adjusting to compensate for barometric pressure or humidity or fuel (ethanol) thats anoter story.

I believe your gas degraded a bit anyway, and has caused some issues with the idle and off idle. In years past, I'd pull it and fix it, but I am reasonably slick on a carb. Anymore, though, I will toss in some Sea Foam to see if it will eat away tiny blockages. If it works, it works, but otherwise, it may make the job of cleaning the carb easier.

<you completely ignored the 2nd part of my question about know how / when to readjust as varying levels of crud migrate int he unmaintained but heavilly tweaked system.

My way or the highway ?? Different methods or approaches scoffed at ??

Update:

I believe my problem turned out to be a dirty/clogged carburetor. I checked the spark and it seemed to be nice and strong. I tried spraying some carburetor cleaner around the gaskets while running to see if anything changed, but it didn't. I also tried turning the main jet screw to see if that had any noticeable effect, but it didn't.

Since a carb kit was not very expensive, I figured I would go ahead and give that a try. I have never done a carb rebuild before, so I was a little nervous. But like I mentioned in my original post, I have a manual and there are some online videos showing how to do it.

So I purchased a carb rebuild kit, removed the carb, took it apart, soaked it in a can of carb/parts cleaner, blew out all of the passages with spray carb cleaner and then with compressed air, reassembled the carb, and then installed it back on the tractor.

The tractor fired right up (which it was doing before already), but when I sat in the seat and engaged the PTO for the bush hog it spun right up without a single hesitation or problem. I was able to go right out and do my bush hogging without holding the choke out or anything. The tractor ran very smooth and had plenty of power and didn't try to go dead at all.

I want to thank everybody for their advice and suggestions. I really appreciate it!!

I also wanted to make sure I posted a resolution to my problem to keep the thread "complete". Many times I have read threads where a poster describes a problem, gets advice on how to diagnose/fix the problem, but then never posts back to disclose how their situation ultimately turned out.

Anyway, thanks again to all!!

hmm.. whattaya know... i'm not so FOS after all.

who woulda thunk that ya need to clean a dirty carb instead of adjusting it.??

weird.

go figure...

Blount. good for you for actually fixing it instead of using the divining rod or tossing salt over your shoulder to fix it. you did the correct course of action despite the protestations of the lazy quick fix crowd.

I've gotten a kick out of following this thread. He did just what I would have done. Turn the adjustment first to see if that would fix it, then take it apart when it didn't. Very logical.

Thanks for posting the results blount and glad to hear you got it fixed. Part of the fun with these old tractors is keeping them running. Maybe it's just me but I enjoy wrenching on old iron.

I'll echo Super55 and say thanks for posting your results!
Glad to see you were able to get the satisfaction of fixing it yourself.
