    Default New E85 engine start

    Just finished rebuilding engine and carbs for E85 and having trouble starting it. It will run for about 10 seconds then shuts off? Hard to check timing like that but the distributer is set as it was before. Hope to have it running for 1 Jan at CFW. The first time I turned the key on fuel overflowed in carb fuel bowls and flodded the engine. I am going to change the oil tomorrow. Should of changed it right away but attemted to start it a few times after I got the float levels right..

    Let's use the process of elimination here since the information is minimal. If it runs for 10 seconds, we can rule out ignition (at lease for ten seconds) but something is going away. Ignition seldom works inadvertently or momentarily although fuel can starve in just about 10 seconds. Let's ask a few questions:
    Do you have a fuel pressure gauge on this?
    If so, is it maintaining the pressure?
    If so, where are the bowl floats set now?
    If not, start with your fuel flow to the pump then work from there toward the carburetors.
    You should be able to check basic timing during the ten seconds it runs to get things close.

    I'm guessing it's fuel delivery since ignition is more matter of fact.

    did you upgrade your fuel delivery system, or running the same thing you ran w/gas?

    "runs then shuts off"
    More here. Shuts off like ignition dead? Or shuts off like out of fuel?
    Or what?
    Pull a plug wire and see if "shuts off" coincides with spark or not.
    Shuts off like oil pressure builds, goes lean and shuts off?

    really need to know what your running for an ignition. If it is the fuel delivery, it must be really weak to not be able to keep up with it in the driveway for 10 seconds. I can run our blower deal longer than that with the fuel shut off. Alot longer! I could fuel that thing in the driveway with a 5 gal can sitting on a 6 ft ladder and gravity feed.
    I assume its a electric pump because you say it flooded the first time you turned the key on. is it still running when the motor stops?
    Can you start it right back up, or is hard to restart?

    After tinkering with the carbs and the timing I think I got it only the flexplate broke a few teeth and the starter gear is toast. Got the parts on order but will not be ready for CFW this weekend. We will still go out there though.

    The only time Iveseen a chevy eat a flex plate and a starter gear was when the wrong spark plugs were installed. Piston dome was banging the plug.

    It must of happened when the carb was initially dumping fuel over two of the bowls. I should have cought it sooner and removed the plugs to flush it out.

    So the motor locked up (hydraulic lock) when you tried to crank it?
