Got the 52 back. Seems to be fine for now. I think the Autolite 437's made a difference. Thanks to Charlie,NY always helpful to me. Thanks also to all of you for your concern. Thanks to Lou Bousquet for his recent suggestions. Sincerely Ron

Ron, I would try to find the cause of the problem before replacing parts. You stand a chance of introducing new problems and can make the problem harder to diagnose. Do a cylinder balance test by connecting a tachometer to the coil to distributor wire and then raising the engine speed to 800-1,000 rpm and shorting out one plug at a time. Each plug should cause the rpm to drop about the same amount. If one or more plugs do not drop the rpms as much, remove that plug and replace it with a new properly gapped plug and repeat the test. If you don't have a tach dwell meter, you can do the test by listening to the engine. This is not as easy or accurate as doing the test with a tach. Tom

Tom's advice is good regarding the vacuum gauge. I personally I have not had good luck with Champion spark plugs. if you have them you might pull them to see how clean they are burning. Give them a good cleaning and make sure the gap is correct. Put them back in and see if that helps.

A vacuum gauge is probably the best tool to isolate the cause(s) of your problem. If you do not have one, it would be more economical to purchase on the to continue throwing parts at the problem, hoping to fix it. Avacuun gauge is also useful in setting the idle. Here is a link on how to use and interpret a vacuum gauge. http://www.secondchancegarage.com/public/186.cfm Your problem could be sticky valves, vacuum advance or some other problem.

Thanks again DRBrown. Your suggested parts have been replaced but maybe should be done again? Ron

First thing I'd check is figure out if spark plugs breaking-down under compression. You don't mention but for the minor cost maybe put a new set in anyway. next up would be plug wires.

Hi Mike I have no issues with the quality of the rebuilds. I have used him several times over the years and swear by his work. Both units were installed on a test engine and performed perfectly. However, when installed on my vehicle, rough idling and hesitation on acceleration exist.
