    If I'm not mistaken, he's running a 532 cu in Ford. Different animal.

    is it a Bendix style starter (centrifugal activation) if so and it is probable a solenoid, but it could not be bumping the fly wheel with out turning, if it was this style of starter. if for some reason you have a solenoid activated starter it is not meshing properly. so here are some questions, what changed, a new ring gear, hows the wiring original, or new, what kind of starter is it i would assume it is a Bendix style, what is it doing, does it spin at all, slowly, does it grind, go in then jump out, does it turn engage then stop turning?

    I'm having the SAME DAMN PROBLEM! My buddy just reminded me to check spark plugs. See if the tips are smashed. I ran into this same problem that Tim (futs) pointed out last year with my chevy. Had incorrect size plugs.

    I had this same problem and I found that it is a voltage drop problem! Most boats have the power source mounted in the back of the boat. Then the wiring runs all the way to the front or dash then back to starter! This is famous on BBC's Ford's not as common! Two ways to fix 1 use a Ford style solinoid as a slave with a jumper at starter! 2 rewire the starter to have a hot wire of a large size to carry the voltage needed to make the solinoid hit every time! I hope this helps! WT


    SOMEONE SAID YOU CAN'T TAKE IT WITH YOU! SO,IM BURNING IT UP ONE GALLON AT A TIME!

    The Ford solinoid is the best way! IMO! And easy less wiring! WT

    pull out the bendix, make sure your fully engaged, and more so not over engaged.

    Also we take a small 1/8 " die grinder and put a small radius/chamfer on all the teeth of the ring gear, Really helps eliminate alot of problems.


    Just my 02 cents!

    My BBC is doing just this, every 6-7 starts the starter will spin and not be engaged to the flywheel making a nasty sound. I put a brand new starter on it, same thing. The start is a bottom mount with zero shims. I dont think it is a shim problem, when it does engage the flywheel, it sounds great. What you guys think?

    Thank you
