Well it’s more like what I’ve done in the past two weeks......
The car has always dieseled a bit after shut off when I installed the 38/38 Webers 15 years ago. So I ordered two idle jet shut off solenoids from Allstate Carburetor dot com. Then, in reading through the Haynes manual for Webers I saw there were 4 idle jets, two per carb. So I ordered two more..... First mistake....
Solenoids came in so two Saturdays ago I set out to install them, going for the drivers side first. Well that had me puzzled, as the jets would not fit the solenoids. I put it back together as before and planned to call Allstate on Monday. But thinking about it overnight, the next morning I went for the passenger side idle jets. Bingo! They fit! I did have to do a little grinding on the carbs with a Drexel tool, as the fit of the solenoid is VERY VERY tight. And for solenoid power I tapped into the line going to the electric choke. While I was there I adjusted the idle, the idle mixture, and the chokes. Spent about an hour doing so with the car running there in the garage (mistake two). In the course of doing this I noticed one of the accelerator pump diaphragms was leaking and I didn’t want to drive it like that. So on Monday I ordered a diaphragm and a spare from Allstate. First mistake solved as the second set of solenoids was unopened and Allstate accepted them back for a refund less a small restocking fee.
Diaphragms came in, and it was a quick installation. Now out for a test drive. And it ran like crap! Coughing, sputtering, and just miserable. Back to the garage, and out came the solenoids. Another test drive and it still ran like crap just as before! Now I realized the plugs had gotten all carboned up during the extended idling in the garage. Busy that Saturday night so on Sunday I took it out and drove the crap out of it. Ran fine after. Back to the garage to wait for next opportunity.
So today I simply installed the two solenoids and took it for a drive. Ran great! And no dieseling after shutoff! Job complete.
As an aside note, the reason I spent so much time messing with the idle and idle mixture was because I had switched from K&N-like chrome air filters (actually from J C Whitney many years ago.....) to a stock air filter assembly, Just made sense to me after all these years that the engine would run stronger breathing the cool outside air instead of the hot air from around the engine compartment. The used stock filter assembly I got off of this site from Dick Steinkamp (thanks again!), and came with the JAM adapters. Once I put this on, the engine was running very lean, because it was breathing so much better. Hence so much time adjusting the idle and the mixture.
Side note number two, the car was faster with the J C Whitney filters than with the identical K&N filters. Be interesting to test it now, what with the Weber 38s, ball of snake headers, and stock air filter assembly.
To top it off and complete my day, I replaced the burned out bulb in the clock. Gawd I hate working under the dash!
