Question about this carburetor. I understand that most folks do not like them, but I have noticed that if you start the car and let it idle for about 10 minutes to heat up before driving off, it runs a whole lot better. Is this just a characteristic of the design?
I had one on my last '26 tudor, and after a careful rebuild it always ran smooth as silk. Mine would smooth into operation after just a couple of minutes in the warm-up phase ... not 10. Before the rebuild not so good.
It should only take long enough to do a final walk around on your car before driving off for it to be smooth. In the day a lot of dealers would dilute their gasoline (Petrol for other countries) with kerosene to make supply meet demand so if you warmed the fuel up it ran better. A Holley NH will give better performance(Faster more pick-up etc) but a good vaporizer will give better mileage
I have a vaporizer in my '27 Touring and it runs great. Sometimes the plate # 6273 can get a small crack in it and need replaced. In line fuel filters are not necessary but everyone has a different view or reason. Drawings by M.V.
I too had little love for these goofy lookin' carbs as they have been maligned over the years. Completely unfounded notion IMHO.
I spent $25 dollars in parts on the vaporizer for the '26 engine in the TT truck and wowee!
I could've lowered the amount spent on parts to $20 but I didn't look close enough at Martin's drawings and wrecked that 6269 tube.
What a sweety! Three pulls on the crank and it's running real nice and doesn't seem to want much adjustment.
I'm actually quite impressed.
I change mine out but mine had obviously been worked on way to many time times looking at the wrench marks and hammer marks on it. I replaced it with a NH Holley it works perfect. Sorta wish mine would have been in better shape, so I could have ran it my car is a late 27. Tim
I have been running the original vaporizer on my 27 touring since my father and I bought the car in the 1960. Runs fine. Had to replace the heating plate twice. The first time that it burned through they were not being reproduced so I made one and then replaced that when repros came on the market. My experience with warm-up time is 2 or three minutes under normal conditions.
