    Got the new Merc Flathead in the 40 and have a pair of 94's on it. Jetted down to 48's fixed some leaks messed with mixtures, had a friend mess with it and it still wont accelerate smoothly, and is still loading up some at idle. Has a 400 jr cam, full oil system, other than that and Reds headers and duals its a pretty stock 50 merc motor. Anyone know someone close I can take it to, I give up! :eek: Oh yeah, after it warms up one carb whistles and after it sits a few its flooded:( Help!!

    Broken/cracked enrichment valve/valves???

    Remove the rear carb, and verifiy the front 4 left. Then switch the carbs and verify the other one. Then put both back and drive.

    Or get two new Stromberg carbs.

    Powervalve leaks are common, the biggest problem with two 94 s I find is an off idle stumble, which us near- impossible to overcome, no real way to tune it out. I went to 97s, and would never run 94s again, they are an ****ache.
     
  5. He isn't a flat-head guy, but he knows as much about engines as anyone on the planet, and he's in Ow***o. He knows multi-carb set-ups!

    The guys at Hot Rod Garage got my buddy's 40 coupe/Tardel 8BA as well as his 53 Merc/8BA dialed in.
