Ford 3000 coughing and dies at full throttle

Hello everyone, I am helping a friend who has a ford 3000 3cyl gas engine that has been sitting for ten years in his barn. Before attempting to start we drained the remaining fuel from the tank and replaced with fresh gas as well as cleaned out the sediment bowl. Both looked very clean and while cranking seemed to have good flow.

The tractor also has new plugs, total rebuild of distributor, and fresh oil. Upon startup the tractor will ideal just fine, however, once some throttle is given it sputters and dies unless bought back to idle. So I was hoping you guys could give me some ideas of what the problem could be. Most people I talk to say I should rebuild the carburetor, but this is the first carburetor engine I have ever worked on so I am a bit nervous about that. I have heard about some screens that could be cleaned but not sure how to access them as well.

Any help would be appreciated! Thanks

You might want to check the flyweights in the distributor and make sure the timing is advancing. Also check initial timing. If the tractor has set up for a while the weights may not be working as they should. A clean carb never hurts either.

I've done many carbs (not as many as Royse), but I would rather clean and synchronize the 6 carbs on a Honda CBX than do my Holley on my 3400 again!

Talk about finicky, the durned accelerator pump (brass piston) will stick if there's any impurities in the gas. That leads to a horrible transition when you throttle up.

It needs to come out to get to the jets. If you've never done it before just take your time, the fuel lines are a bit of a chore. I found disconnecting the sediment filter from the fuel line gave me enough movement to pull the throttle linkage.

"Would I be able to remove just the jets without removing the carb?"

I rebuild a lot of carbs for folks, mostly Marvel Scheblers now.

Lots of Holleys and Edelbrocks in my racing days.

The Holley on my 3000 gasser was a new experience for me.

It turned out fine and works well.

But, if you have never worked on a carb, I would hire it out.

As big of a PIA as those things are to get on and off the tractor,
I'm not interested in rebuilding them myself because I test all
my rebuilds on my tractors. I'm sure someone does them though.

I would be willing to help over the phone or via email if that helps.

Since you have worked on dist and plugs I'd say Copperhead has the likely issue. Carb jets can get gummed in just a few months especially with ethanol gas, much less years. What type of carb?

Thanks for the replies, the carburetor is a single barrel holly. I have a rebuild kit on order so hopefully this will fix the problem. Is rebuilding one of these carbs difficult? Would I be able to remove just the jets without removing the carb?

Also, I am unsure of the tractor year.

What year tractor?

Ive read that the holly carbs on these things are quite horrible and dont take adjustment.
Someone in the past put a zenith carb on my 3400. It seems to be a common swap but rather $$.
How about checking the points before moving further?

My guess is you have the high speed jet stopped/gummed up.

Today's Featured Article - Antique Tractor Wiring Basics - by Curtis von Fange. One of the most neglected parts of old tractors is the wiring. After sitting in the elements for half a century or more much equipment wiring has deteriorated to sparsely covered strands of copper or other metal. Plastic insulation has cracked, mice have eaten through the older clothed style coverings and the exposed wires have reacted to winter moisture and salts by turning blue and powdery. Terminal ends have corroded, rusted or just plain evaporated away. Aged wires not only keep an engin ... [Read Article]
