I had a tough time finding the ISO 32. They didn't have the ISO 22.

I filled the FD with the hole at 2 o’clock until it weeped out. If I lower the fluid level it will lower the pressure I’m assuming. So you are saying that the pressure built up is going to cause too much strain on the “coupling” and drop the engine rpms?

I use the TDH ISO 32 that everyone says is the closest to Mopar Fluid Drive fluid. When I drained the FD it looked like standard 10wt oil. When I drained the transmission i found this..

I have corrected the accelerator pump issue that I did not know I was having. The throttle shaft was wiggling where the linkage connects. I secured it. The accelerator pump was not going up enough for it to get a long stream, it stopped about halfway through the throttle opening. I added a couple washers that are the size of the linkage so it won’t bind. Now when idling and the pedal is pressed it revs beautifully. I increased the idle to 700rpm and when I put it in gear and released the clutch it dropped down to 350rpm. I released the brake, pushed the accelerator, and.... it stalled. So I started it again, put it in gear, released the clutch (dropped to 350rpm again), I pushed the accelerator very very slowly so it started to raise the rpms, released the brake and it took off very slowly. So obviously the issue is that the engine drops too low in gear when stopped. How do I correct that? Even at 700rpm idle it dropped in half. So does that mean I need to put the idle at 800-900 to get 400-450 in gear at stop? I know that can’t make sense to do.

It’s a Stomberg BVX. The book says I should have the BVXD-3 but it didn’t come with it so I don’t have a dashpot. I used a timing light and have the timing a few ticks BTDC and the gaps are right to the best of my ability. The stumble happens even when I am in neutral unless I open the throttle extremely slowly. I checked the vacuum advance and it operates like it should.

Based on the book the engine should idle at 450-500rpm. The car is obviously not running just fine or it wouldn't be stalling when you attempt to take off in gear. When it is idling and you press the accelerator it stumbles then revs. The carburetor has been rebuilt 2 months ago and it is acting just the same as before. The timing is just before TDC like the book says. Even in high gear it should not stall, it should just take off slowly. If I rev the engine in neutral to 600rpm its going to scream every time I come to a stop and push the clutch in. I don't want to mask a potential problem by raising the idle. The compression in the engine isn't great but its not terrible. The shop manual says that with all the plugs out and the throttle wide open the compression should be 120-150. This is how mine read: 1: 85 2: 90 3: 92 4: 92 5: 100 6: 100 The compression test was completed twice with the same results. Could a vacuum leak in the intake manifold cause the stumble at initial acceleration? Could it run itself too lean and then straighten out?

I have a 1951 Dodge Meadowbrook with the standard 3 speed transmission fluid drive. When it is idling in neutral it runs around 450-500rpm. When I put it in gear and take out the clutch the engine bogs down to around 200-250rpm. I have changed the fluid with the TDH ISO32 like many of the forums here have said to do and it still does it. When I try to take off with the clutch out it either stalls or stumbles for about a second then takes off. When I am rolling down the road it runs and shifts fine with no hesitation. When you have it in gear with the clutch out, lets say in second gear, and you release the brake without pushing the accelerator it pushes the car forward like it would in an automatic transmission. Is the engine supposed to lower rpms when in gear with no clutch and no acceleration? Is something getting hung up and causing it to act like a normal standard transmission?
