60 Fuel or Ignition Issues?

[Anonymous-0]

60 had been running difficult, die but start right back up. Changed Points and condensor two weeks ago, perked right up. Yesterday started it up to fill corn bunk, ran for a while OK, then started to act like starving for fuel, no matter what choke position. Would not get out of it's own way, wait a couple of minutes would start and run for about 45 seconds, then act same way. Am I looking at fuel issues or still some ignition issues. Day of point change was close to 50 degrees, yesterday 20, but started and ran fine...for a while. Any ideas

Simple do your trouble shooting 101. With all gas engines you check spark the moment it dies. You need a good blue white spark that jumps a 1/4 inch gap or more. Next you check fuel flow out the drain plug on the bottom of the carb. Let it flow for a few minutes catching it to look for water/dirt etc.

Check screen in fuel bowl had that problem with my G

coil

Hanging a timing light on it and watching the flash is still the best way to separate the two. No cost and very little work is a hard combination to beat.

My bet is coil if it only does it when warm. If temp of engine makes no difference, then check fuel supply. Do you have the auto shut off fuel supply?

If it was the coil Fred it would not start back up till the coil ah time to cool off say an hour or so.
By the way hows you doing down in snow land??

You should check all the issues that were mentioned above for sure and also since you mentioned that it was running fine at 50 degrees but not at 20 take a look in the air cleaner for ice as ,like you said...it wont get out of its own way when that situation ocoures.

Yes, has the oil pressure shutoff still on it, and sediment bowl filled up after cleaning.

Guess I never thought about that, would condensation in the oil bath freeze it up enough to stop air flow that much?

Thanks for all the replies, got a few things to check. Temperature is supposed to warm up to mid 30's on Thursday, so hopefully can get it started and work through some of the issues. May just have a coil and plugs anyway, ready for whatever.

OK, I have a couple more questions on the coil possibility. You said it does it when warmed up, but when I did the points, I ran it for about 30 minutes after that. Ran it around the "farm" in high for a stint since it needed some limbering of the running gear anyway, and for fun (much faster than my 35 B), so if the coil was going bad wouldn't it have shown up then? Or can a coil just go the next day? Never had a coil issue with the old B, only with tired arms.

Sometimes the rubber plunger on the stem sticks to the top of the housing and can really give you fits with how it runs.

Hey Richard. There is still ice down here today yet! Crazy Global Warming!! Lol. With the 60 when my coil acted up it was after it got good and hot. Then she would cool down for 30 min or so and shed fire right up again until she got to some unknown magical temperature and fall flat on her face. This was in the summer time so I'm assuming with cooler ambient temp s the restart time would be less. Fuel issues would most likely happen cold on start up or in high loading. IMO

Coils can and do fail in an intermittent mode which means that they will do just about anything they darn well please at any time and no one is in charge of that. They will fail hot one time and work hot the next or cold the other way around. Miss like crazy for a while and straighten out for the rest of the day only to not fire at all the next day, no rhyme or reason being the most obvious symptom. Anything is possible with a bad coil. So the only real way to be sure it's the coil is to replace it and hope you don't put another one just like it in it's place, then you judge the old coil by the performance change. If you decide it was the old coil - don't save it, don't even keep it around as they tend to come back and haunt you after you've forgotten that it's bad. Only good thing about a truly intermittent coil is that they are pretty rare, it's usually dead or good with them by far, but since it is a failure mode of a coil to behave like all of the above, we just need to be aware of it and replace suspect coils before they can drive us stark raving mad.

You know in all my many years of messing with engines and tractors I have only had 1 coil ever that went bad and that was on my Ford 841 tractor and it now has a coil off a 1969 Chev truck on it. Back when I was still a teenager I did have a coil explode on a VW bug I had but the ignition was left on and it was a 6 volt coil hooked to a 12 volt battery and that when it blew sounded like shot gun going off

I chased a similar issue for several years. It would just die randomly if I was working it. Let it sit for a minute or 2 and it would fire right up. Rebuilt the carb (twice), plugs, wires, cap, coil, points and condenser. After each "fix" I would tell myself I finally took care of it and out of no where she'd just die. Turned out to be a small piece of leaf in the fuel tank. If I was working it, and the stars were aligned just right it would find itself on top of the fuel outlet and nearly seal it off, no fuel, no run. By the time I would climb off and grab some tools, the carb would be full again and no more suction to hold the leaf in place. When I would pull the fuel line I would get fuel, same if I opened the carb drain. Finally after years of this I looked in the tank with a flashlight and saw the little Ba@@rd. Made a scoop out of window screen and coat hanger and fished it out. Was a real blow to my ego for a long time, the fact I couldn't figure out what was wrong with this stupid simple tractor. I'm feeling much better know.
