Ford jubilee

[wcurley000]

My Ford jubilee is occasionally back firing and has little power and stops when only small load. Firing order is 1 2 4 3 and number 1 cyl is connected to the 10 o'clock post on distributor with the 4 cyl on post nearest coil connection all in clockwise order. Good spark at plugs. Cleaned carburator. Full tank of gas. Changed plugs, points and condenser. Suspect a weak condenser. Plan to check compression. Plugs have a lot of black residue after only short time running and exhaust is black when first started but gets better as engine warms. Why no power and hard to start? Also stalls when even under light load.

#1 back smoke means it is running rich. When was the last time you checked your air cleaner and dumped the mud and water out of it and fill with fresh oil?? What spark plugs are you running?? I run NGK3112 plugs in ALL my Fords and a few others also. You might also try screwing the main jet screw in a 1/2 turn at a time and see if you can screw it in to the point the engine shut down

You may want to adjust your low speed mixture for more air. It is the small screw. out for more air. The larger screw is your high speed/load adjustment. It has no effect at low speed no load conditions.

Is your choke operating right ? Check to see if it is moving full open.

 

[wcurley000]

The choke is ok. I have cleaned out the air cleaner. I have adjusted both the high and low speed screws.
A friend said I might have a bad carburetor gasket and it might be getting too much air and starving the engine. Replaced it and no change. Now wondering if I have a leak in the intake manifold.
Also wondering if governor is working.
I had it started again and it ran for about a minute with no load and then died out. Had occasional backfires. Tried to start it again and won't even fire.
Do any of you have problems with condensers?
Any suggestions are welcome.

I think you may have two problems. Something is making the mixture to rich, setting on the main jet is to far open or the float is set to high. Secondly, I suspect you may not be getting enough gas flow to the carb to support the load. Did you check the flow of gas out of the carb drain plug? It needs to be more than a trickle. When you cleaned the carb did you remove the elbow that the fuel line connects to? It has a fine screen that can plug and stop fuel flow. See number 17 in the linked diagram.

I did not remove the elbow, but I'm going to do it right now. Thanks.

Screen in elbow was clean. Cleaned thoroughly with carb cleaner. Checked flow from carb drain plug and it was good.

He has checked and adjusted everything. end of story. It must be running perfectly now.

Started and stalled in about 1 minute. Checked and no spark at the plugs.

Try a hot wire from the ignition side of the battery to the ignition side of the coil and see if it runs that way. If it does and stays running your problem if from the coil back to the battery. If it doesn't your problem is in the distributor cap. If you have replaced the condenser good chance it is bad right out of the box NEW
