You will find that there are many friendly and knowledgable people on here.
If you need it on choke to run it means it's not getting enough gas. Like chopperfreak stated I'd give it a good cleaning again and see what happens. If that does not help you may need to play around with the adjusting screws or adjust the float to allow more gas in. And keep us posted.......

Also, the jet screws are extremely sensitive, and once you get the high speed set to run proper, then that affects the idle jet setting, so you have to go back & forth a few times to get it right on both low & high speed circuits.
Other than Tecumseh carbs, these DD's are about the 2nd hardest to dial in.

Now I need to fix a couple of cosmetic problems. One of the hinge points on the upper grille is busted, and the cracked dash was fixed with a piece of plywood by the previous owner. Any help in locating these parts would be greatly appreciated.

George is on to something there about vacuum leaks.
The Onan from FL was running on one cylinder due to an ignition issue. Fix that with a coil.
Then it would only run on 1 cylinder unless the choke was on. After 3 times though the carb I started looking else where. Found the intake manifold opened up at the seam where the 2 halves are put together. Put JB Weld around the whole seam and it is running without the choke.
Still has a bit of a gallop but as Daniel says it take several setting to get it right. Also found that the air filter makes a difference in the adjustment.
Suggest air filter in place when making the adjustment.
