remove carb or bring the Jeep to the specialist?

I use too much fuel, so I have to check the carburetor.
The specialist (on old mechanic who knows well the solex carb) is busy, so maybe it is easier if I take the car off and bring it to him.

But it is better probably to bring the Jeep so he can check all.

Is it easy to take off the carb? Problems?

 

Easy to remove the carb. Remove air filter, disconnect throttle and choke, disconnect fuel line, remove 2 mounting bolts and that's it.

Probably is better to take the whole JEEP to the mechanic so he can check the condition of the carb while it's on the JEEP and running. He can check vacuum and other things that may be contributing to your problem.

 

Alan.....what mileage are you getting now? km/Ltr.

 

2X. unless the person has some specialized equipment, there is no way to check the carb without a motor under it. Perhaps our member Scoutpilot could rebuild it but he would still bolt it to a motor to do some fine tuning. In other words, take the entire Jeep in.

 

Yes, many times I've seen "bad carburetors" that turned out to be vacuum leaks, fuel delivery problems, or ignition problems.
Take the vehicle to him so he can adjust it properly.

 

The engine works very well, there is no smoke, the spark plugs are new.

I just use the Jeep for small moves, no more than 2km each time, and in slow speed because I go getting goods in farms around, I use tracks in 2nd or rarely 3 gear except when I put the 4WD.

I just put 43 liters of fuel for 105 km!

I have to use the choke to start but only 10 seconds, (when the weather is hot) then I let turn on the hand accelerator during 1 mn and it is ok.
When hot the engine starts immediately.

Of course in cold weather it is horrible.

The subject is : if I want to bring the Jeep, I have to take an appointment, there is 15 days waiting. We are before holydays and it is a good shop.
I believed that bringing just the carb the specialist of Solex could check rapidly.

But I understand that it is better to bring all.

 

Allan,

Wow 43 liters/105 km is 5.74 mi/gal -- that's terrible... like others said, take the jeep to him so he can check timing, carb etc...

My F-head gave me around 12 mi/gal before I did my valve and timing, now I get between 14 or 15 mi/gal in town and 17 to 18 mi/gal on the highway. The compression is good but I still suspect a loose guide or burned valve - I get no smoke out of the tail pipe but my vacuum gauge oscillate at idle.

If you want to take the carb off a S-wrench really help getting to the bolt against the valve cover

I did the math and came up with the same mileage as Pierre... 5.753 miles to the US gallon. Is the vehicle/engine idling a lot? There is a bunch of unburned fuel going out your tail pipe.....if your odometer is accurate....you would definitely smell it. I would also check your speedometer/odometer against a smartphone app with a tachometer.

I can't imagine an engine running that well if in fact the carb is that much out of wack. I get about 10 or 11 MPG around town with the F-134.

 

All good advice Alan. Lots of idle time, low speed, short distance is not at all good for fuel mileage. In fact it can be damaging the engine and not allowing the battery to be fully charged. The Jeep needs to be driven.

 

I filled the tank 2 months ago.

But my Audi, when I start it, says that I am at 43 liters per 100km then it becomes normal.

I understand that there is a problem somewhere but all works well so I am not in a hurry. But as soon as there is bad weather, I bring the Jeep.

 

Yes, sure but I have nowhere to go!

I am myself sorry for this, but I am 67, it is in my mind, I apologize!
During many years I moved a lot, jumping in planes, renting cars, crossing France for just a sunday at the sea... no more juice.
I should see a doctor!

 

Over 2 months, evaporation will contribute. Unlike modern cars, the tank is vented to the air, so any vapors will be lost.

If the Jeep is going to sit for a while, use a clean stick and measure the fuel depth. Then measure months later. I think you will find the level has dropped some.

 

Allan,

 

Thanks for the solutions.
The tank is at the rear, quite impossible to dip something in it.
I have some building works to do in my county house so the Jeep is not my main problem.
When I bought it I had in mind to make some tourism with the children, but they work and are busy.

So... maybe I'll move to a better place for retirement, I was looking to a place near Omaha beach... near the sea.
But nothing before 1 year, I sell our flat in Paris and afterwards...

Just to say, I pushed the engine a little bit in a field, works very well.

 

I hope you understand that we aren't giving you crap about your Jeep or you. You enjoy your Jeep but it should be a lot better about how much fuel it uses. Don't let it idle very long, just long enough to get the oil pressure up or scrape the ice off of the windshield. Drive easily until the engine temperature is in a normal range.

 

Of course I trust you all.
As said it is not my priority, I'll wait until I can get the mechanic, and the good one.

Concerning temp and oil pressure, I have the military willys direct gauges, so I know exactly what happens and I take care.
