I'm running a holley 1940 on a 200. I bought it New Old Stock a few years ago, and it has the larger throttle plate size. It runs pretty well, but I am thinking the main jetting was set up for a larger engine - 240, 250, or 300. My problems are - it doesn't run very smooth at medium throttle until the engine warms. It also tends to stall when starting off from a stop before the engine completely warms. I also occasionally experience deiseling after a short trip, and on rare occasions the engine floods and I have to hold the choke open while restarting to clear the flooded condition. These problems go away in warmer weather.
I'm thinking the main jet size is a little big, and when the choke is closed it's just a little too rich. The accelerator pump is enough to kill it when the choke is closed. I was going to try jetting down two sizes to see if the problem gets better. Does anyone know if this carb takes standard size Holley jets?
