I have four pages of Ford service bulletins regarding the operation and repair of the concentric carb. I can scan and e-mail them to you. Just leave me a PM (personal message) with your e-mail address, as multiple page posting doesn't fit this forum. Posting your e-mail address here will almost always produce unwanted mail.

Tracker you could check out your distributor advance with a timing light. You could check for obstructions in the exhaust with a vacuum gauge. Your problem could be due to a weak spark also. Check for sufficient fuel delivery as your fuel line may have become partially plugged over the year. Let us know what you find. I hope the shoulder surgery went well and that you are back to normal.

You might want to check the air cleaner and the exhaust system for the presence of a rodent or wasp nest. You could also have a partial blockage in the fuel line somewhere between the tank and the carburetor.

I suspect the the carb is your problem. The coincentric carb on your car is a complicated device, and if the float level has been affected, it could create the lack of power. Have it looked at by someone who knows their stuff. Meanwhile, be sure the delivery of fuel is sufficient, and the pressure is correct. Both the carb and the fuel pump contain rubber parts, which are affcted by alcohol that is present in all gas.

In preparation for major shoulder surgery, my stock std shift 1951 Merc was put away for over a year...started every month or so for short periods....all fluids changed prior to hibernation and running perfectly when stored. This week it was rolled out for a maiden run after 15 mos and had some major changes in performance. The engine starts , idles and runs perfect up until about 30 mph. At 30 mph it begins to act as tho it has a throttle limiter ...the engine does not miss, cut out or do anything abnormal except ...it will not take any more throttle advance/gas and will not get much above 35 mph, It just bumbles along and when you take your foot off the accelerator from full to normal , it just resumes at about 35 mph without a hitch. No amount of feathering the food feed seems to make any difference. I'm thinking the dist is not advancing but that's just a guess on my part and I don't know how to prove it. I'm really hoping someone can give me some diagnostics I can perform on my own to get a handle on whats happening. As always , thanks in advance for any suggestions on this. Regards
