    I have dual 94s on my flathead. When I hit the brakes and stop the engine wants to stall and then it speeds up. If I set the idle high enough so that it don't stall when stopping then the normal idle is way too high. I tried raising the float level thinking that fuel is sloshing away the jets but that didn't help. Any ideas?

    Sounds like timing or vacuum.

    Check the float levels. Running fuel level should be 11/16" below the gasket surface on the top of the bowl. Requires a "standpipe" tool that can't be bought any more. I described how I made mine in another thread. I hope it's not confusing. Oldness does that to a fella.

    If you have power brake booster, disconnect it's vacuum line then test. I had the same problem, searched everything, then tested the booster. Found it had a leak. Might help.
