I'm a fellow member in need of some help! I have a 52 Crestline Vic that is running rough and has a hesitation. I have had the fuel pump and carb rebuilt. If there is someone in the area that has flathead experience, I would like to discuss my situation. I live in Middlesex County Massachusetts. I can be contacted through my email address: artron9@hotmail.com. Thank you! Ron.

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.

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.

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

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.

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.
