So far, so good. The carburetor idles wonderfully and accelerates much better than the previous Atlas/Holley Vaporizer set up. The only issue was that it was extremely difficult to start when cold. I drove it over to a friend's house on Sunday who witnessed the hard start and it had only been sitting for twenty minutes. I told him that it was missing the "air filter." He said that he carburetor was getting too much air flow and that was the reason it was starting so hard.
I had placed a Sears lawnmower filter on my the Atlas, but the Kingston required a different attachment. So, I had some brass sheeting that I riveted together to create a tube, then wedged the air filter onto the tube and screwed the brass tube into the air intake. Instant improvement! The car now fires up quickly and reacts like it should.
I drove it to work today (school) and showed several of my classes who had never seen it before. I am excited to see how it will pull up the hill going from the Puyallup Valley to South Hill.
I am curious to know how many cars run the Kingston Gasifier/Vaporizer set up?
If adding an air filter will make it start there is something wrong with the carburetor. Or the air filter is far too restrictive.
It took an hour to get home - Puyallup traffic was CRAZY tonight. Despite that, that engine ran like nobody's business. With the previous Atlas Vaporizer, the car struggled up the hill; with this Vaporizer, no problem whatsoever and I was starting from a dead stop at the bottom of the hill. Acceleration was awesome - gas mileage, not so much. It wasn't any better than the other carburetor, getting somewhere around 13-14 mpg, 15 at best and that's if I angle the stick in. Granted, a lot of it was sitting at lights and idling, but still, I was hoping for something a bit better.
Jim, I have a B-1 gasifier on my coupe. When I drove to all 48 states, I averaged 21 mpg for the 10,000 mile trip. This was running full throttle most of the time. My gasifier starts easily hot or cold. I don't think the gravel strainer that you are missing has any significant resistance. My gut reaction is that something else is wrong. Perhaps it is maladjusted.
I don't have much experience fine-tuning carburetors. Any advice on what to do/look for? Thanks.
Jim, check out this thread:
Here's the latest. The car now fires up cold, without the air cleaner, thanks to Jim Mahaffey. Jim sent me a copy of the Ford Service Bulletin from September, 1927. The title: "The Kingston Vaporizer - How It Operates" written by Murray Fahnestock.
The trick when starting it cold is to get the 1) open the dash fuel needle three-quarters to seven-eighths of a turn and to open the low speed knob one and one quarter to one and a half a turn. Pull the choke lever and with that setting, the car fires up immediately.
I think each Gasifier is a little different, but with mine, within the first twenty-thirty seconds, the choke is released and the dash fuel needle is backed off to about 1/2 a turn - at least for an idle. Once the engine is idling well, the low speed know is turned in 3/4 of a turn. Quoting Murray, "To make low speed mixture richer, turn needle in. To make it leaner turn screw out." Interestingly, when driving, even at a low speed, I have to open up the fuel needle about 3/4 of a turn.
I took a twenty mile trip last Sunday and a short five mile trip today. Both times, the car accelerates wonderfully and last Sunday, it averaged 20 mpg - if I read the stick correctly. All in all, I am really pleased with this carburetor as it is a significant improvement over the Holley Vaporizer.
