I'm a fumbling idiot and my flathead doesn't run...

    Also, ground issues are very much worth examining on a fresh car--all that paint blocks ground at every step. Internally, plate must seat well, externally a jumper from condenser mount screw out to solid ground would not hurt a thing...

    Once you get it running you can drive it by if you want and I can help you figure out why it's running so good.... :)

    Good luck with it!

    That's the thing... My points aren't burning... They are just losing their gap. The contacts actually look brand new and clean, but you can spin the cam on the distributor and actually feel a "lesser" spring tension.

    As for taking the dizzy off... there really is nothing to screw up here as it only goes back together one way. I don't think the actual mounting of the dizzy to the block could be the issue.

    I got new points from NAPA like Bruce & Keith instructed as well as a new condensor. I plan on filling the rotor just a bit tonight and then giving it a shot. If it works, it confirms by initial stupidity. If it doesn't, then I am going back to the drawing board and pulling you all in to hell with me!!!

    Thats a great attitude Ryan. Just a warning... there will be more ignition troubles. It's old and for some reason, they pop back up like gremlins. But I have to say that constantly wrenching on the old stuff has taught me so much and makes me thankful for all that new technology, but for some sick reason, I still get a smile when that old fort flat motor starts sputtering and it's time to pull over. What's it going to be this time that I get to figure out like a puzzle and then get back on the road again? Even my girlfriend is used to it and usually beats me to opening up the hood!

    Are both points losing gsp simultaneously?? Is there any roughness detectable on the cam by checking with fingernail for any catchyness?? Is there any side play in shaft?
    Cam finish should be very slick--looking at the crab in my office, I can actually see the point rubbing blocks mirrored in the faces of the cam.
    Breaker oivots have a brass washer, then a little cotter, and have essentially no play up-down or rotationally on the pivots. Points held down by two screws with lock washers, adjusted by eccentric screw...all hardware look happy??

    Question: Are there parts available to rebuild one of these distributors and if so where? ie. bushings, breaker plates, point cam.

    Check out Joblot, C&G, Macs...between them, you can find almost everything.
    I'll be doing a complete tech on these soon.

    It's easy to find low-mile rebuilds for sale, though, and I look for good tight ones that just need cleaning and points. Ford and other exchange programs mean that there are many that actually have low miles since last factory rebuild.
     

  12. I did the same thing on the Rocky33. It didn't take much for the rotor to break. I didn't file mine (didn't even think of it at the time)but finally got lucky on rotor #4 and it fit w/o hitting.

    Yeah, they seem to be losing gap simultaneously. That said, the new ones from NAPA seem to be doing fine. The cam is perfect... It looks polished it is so nice... And I add a little white grease to keep things smooth.

    Breaker divits are new and cotter pins are fine. They sit right. Hardware is old, but all there.

    Went though a similar deal with my flathead powered 29 roadster, points, rotor, condenser, plugs wires, carb kit, flushed out gas tank, Damn it runs good! I love it...............

    Also, there is special grease made to be used very lightly on breaker cams; it is a bit stiffer and waxier than most regular grease. Still made, you will have to find a parts man old enough to understand the request...

    Dielectric grease works well.

    Before the drags this year, I replaced my cap and rotor with NAPA parts. Car was missing bad under a load all weekend. When I got home found that the rotor had worn the contacts on the cap almost down to the plastic. Distributor shaft was tight, so I replaced cap and rotor again, and noticed replacement rotor was again hitting contact points on cap very hard. I broke out one of the wife's nail files, and filed down the rotor contact a small amount. Has ran fine ever since.

    In these parts when a flatmotor doesn't run rright we declare a flathead emergency, everything stops till the problem is fixed.

    Ryan,

    Hope you're not having problems with the points I sent you. Borg Warner and Echlin (NAPA) are owned by Standard Motor Products. So the points I sent you should be the exact same as Echlin (NAPA) points. The cam lube that Bruce is referring to is Standard part number SL-2 and should be availabe at any CarQuest auto parts store. It is heavier than dielectric silicone and lasts longer on the rubbing block of the points to help maintain point gap longer.

    Ryan, glad you got it going again...

    sometimes the simple is the most overlooked... i messed with the 455 in the willys for two hours before i remembered to check an see if the points were actually GAPPED right . :rolleyes:

    Man, I know this is a little late, but if your point gap keeps changing after only a short peroid of time, I'd want to look at the threads in the breaker plate and the threads on the hold down screws that hold the points tight. As time rolls on these tend to get sloppy and may be letting the gap close up because the threads are on the verge of being stripped. Way back in the 70s this was one of the things my old boss insisted we check on every tune up that involved points.
