67 slant with 1920 holley dies when engine heats up and choke opens.

The remanufactured holley 1920 carb...not so much:bogging down for some reason (possibly due to the one extra vacuum hole for anti-icing I had,which I plugged.But I also left it unplugged,and drove the car,filling it up with a little bit of cotton cloth for a temporary fix so it could breath,and the car ran,but not any better,or worse.Remanufactured carbs are now suspect in my book.I decided to clean and rebuild my old carb,and I have no experience with carbs.I understand the Venturi principle,but that is it.I did first put it on the car without rebuilding it (I had only cleaned the needle and seat assembly),but the cleaning,as Slantsixdan thought,didn't help it any.Well,I feel like a NASA engineer who had worked on the Lunar Rover,the car runs great,like it did before.After disassembly,I sprayed every orifice I could find with carb cleaner(next time I will invest in the soaking solution with pail you can buy).I then followed by boiling in water,but keeping one pivoting plastic piece on the main well and economizer assembly out of the water not to damage it.I could have removed it,but didn't want to take a chance cracking a probably near 50 year old part.I have no compressed air,so I put the carb in a warm,dry oven to dry it out.The carb kit and illustrations were great,and I took pictures prior.I am thinking of cleaning and rebuilding the remanufactured carb now.YAH BABY,GET YOURSELF SOME OF THAT,R. Rawlings,A. Kaufman,D. Short,E. China,and Slantsixdan (they would be keeping good company with you, Slantsixdan).I'm stoked that I have my car back,instead of a 2,750 pound,$10,000 paperweight. Rich
