Oliver fuel issues

[OliverDeere]

After fixing up an Oliver 88, it has suddenly started acting very strange. It starts, runs, and drives for a little bit before violently surging or stalling. Then to start it back up again, you have to put the choke on. The carb on it hasn’t been touched in 20+ years and ran fine just the other week. Thanks!

Sounds like it sucked something into a jet.

 

[OliverDeere]

Yeah I’ll have to crack it open and find out.

I guess before you pull the carb pull the fuel like at the carb and check fuel flow. My 1600 did something similar to that a few years ago and it turned out to be a big black beetle that had somehow got into the fuel tank and was wedged in the outlet port. That was dumb.

 

[OliverDeere]

I guess I will check that and the sediment bowl as well. It started this behavior after I refueled it so some sediment must’ve gotten stirred up.

I had a running out of gas situation with my 1750. Thought I taken care of it by cleaing the fuel bowl but ending up removing it completely and findind a small white substance in the tubes feeding the fuel bowl. Had to use air to remove it.

 

[OliverDeere]

huh. Weird stuff can be in fuel systems sometimes.

 

[scootergmc]

Yep. I also like to stick a flashlight or camera in the tank to see if if there's anything in it, something lodged in the sump, etc.

One of us kids (not me) dropped a pop sickle stick in the gas tank of Dad's 66 one time. I got heavy and sank and would drift over the hole now and then and cut off the gas. I had a 7300 combine that would run fine until you'd put it under any load. There was a kernel of corn stuck in the stem of the sediment bowls on that. It would get enough gas to run with no load.

 

[OliverDeere]

That combine had the same problem that I have. guess it is clogged somewhere.

 

[OliverDeere]

It is done stalling under load, but now dies whenever throttled above half when in gear. My guess is carb since there is a lot that can get plugged or gummed up

As posted earlier, check fuel flow to carb, then probably a carb kit is in order. I’ve got a 70 that (I’m guessing) still has the original carb and gasket set in it and fiddling with the choke is needed for higher RPMs. I’ve got the kit ready, just waiting for the necessary round tuit and hoping the float is reusable, as all suppliers I talked to had no replacements.

 

[OliverDeere]

Ok. The flow was good after cleaning sediment bowl.

I once had a I H fuel cap that would not vent, caused similar issues., Drilled a small hole all the way thru it, problem fixed.

So things have improved? If the sediment bowl had enough gunk in it to cause problems then chances are good your tank is due for a clean out as well.

 

[OliverDeere]

I don’t think the tank needs to be cleaned too much. Not an expert but is that dark cloudy stuff bad?

Had the same happen. My gas cap goes on and stays on but is hardly sealed, the action of the motor sucking the gas out of the tank produces a draw, it draws through the seal and tank; couple that with I use cans of gas to fill it, not at a pump. And the tanks rust on the inside, what I found was chunks of rust.

 

[gary66]

The surging, stalling, restarting with choke on are symptoms of restricted fuel supply

Other caps will do this as well, was running the generator to milk many years ago during a blizzard, vent would ice over, tractor would stall, by the time I got to the tractor it would start right back up, it would run for 15-20 minutes and stall again. so good flow out of sediment bowl does not mean anything for continued flow if vent is plugged.

If stuff was in the sediment bowl it's coming from somewhere. Give that tank a swirl and see what moves around. It doesn't take but a honeybee or little piece of debris to clog the port to the sediment bowl. Then they float in and out, in and out, and you're at a loss why it's intermittent. Not saying that's your issue, but peace of mind is peace. I really can't tell what that crud is, but if it can travel into your sediment bowl, you might have a winner.
