BigDanT 11-25-2012 16:07:16 199.250.3.70 Report to Moderator	Have a friend that's got a '50 PU 6v 239 v8 flathead that is running poorly. Starts and idles great but when trying to accelerate it falls on its face. Will not rev up, does not back fire but boggs down. Have rebuilt carb, checked vacuum advance, checked points cap rotor.Spark will jump 1/4 in. sediment bowl stays full, float bowl full.Any ideas on what I should check next. Thanks Dan [Reply]   [No Email]

If so might be the accelerator pump - there is a leather cap in there which might be worn out or dried out - same problem with my 53 V8 - check that when you pump the gas you are getting a good 'squirt' of gas through the two small tubes located just above the air intake on the top of the carb. lee [Reply]  [No Email]

After weeks of looking for the problem we unbolted the exhaust pipe from the exhaust manifold and the engine then operated normally (although loud of course!). The problem was in the muffler and the result was the engine could not breath more air than was required for idle speed........if you get to wits-end, try it. [Reply]  [No Email]

If the insulation is rubbed off and touching the metal of the distributor that is the culprit. To test for this condition, remove the vacuum advance hose from the diaphragm and if it will accellerate then you know that is the problem. Zane [Reply]  [No Email]
