    Gary–more cheap advice/thoughts: 1. what is your head gasket material–and if it’s not copper would that help in heat dissipation? 2. how about using valve seals and taking the time and trouble to carry and add a tad of Marvel Mystery oil or such at each fuel stop to take care of upper cylinder lubrication. If it doesn’t pass a leak down test at the guides, then I would think that it would be having a leaning/heating effect (for what it’s worth-if anything.) keep on keepin’ on–ron

    • evening Ron, hope you guys are good. am using a solid copper gaskets. and thought about the guide seals, ran the ideal by Jim Wall in Denver, a Indian engine builder and racer. he has built engines using and not using them. I sure hope to be to a point shortly to put on more miles and see if my heating has changed. I m hoping so. and I ll be running a bit of 2 stroke oil also. clocks a tic n. gary

    Hi Gary and Linda,
    Certainly agree with “Charlie” on how strong the Chief sounds. Glad that the “dead spot” is no more (that was a wide grin you were sporting). What about the front cylinder heat issue? Do you get the same temp. readings if you switch front and rear cylinder indicator wiring? That is a wide temperature disparity and I can’t imagine, if it is accurate*, that you wouldn’t have some noticeable symptoms of overheating by now.

    *the earlier picture of the spark plugs showed one looking about the same as the other.

    Continue to be impressed with your perseverance and we hope that you can finish up all with some days to spare so that you can relax at least just a little before starting out and don’t arrive in FL in a totally frazzled state.

    Unless there is a drastic need to change plans, we are definitely going to try to make Daytona Beach and follow out to the end of day four in Clarksville, TN.

    Ron (and Dixie)

  5. morn n Charlie, wish i could share helpful wisdom with you. after on going changes to the 344 carb, rechecking or trying to out think other changes i ve made. Jim Wall of Denver took her for a spin , did some fiddling, said it was close but carb was not right. loaned me a 344 that i tanked, installed, tuned and no more dead spot. i was starting to think my upping the intake nipples , manifold and templet port / polish , cam change was the fault. for what she is i m impress with the way she pulls. still a ways to go. but closer.

    It sounds awesome! That can be a tricky issue to fix. So, what exactly did you do and what’s your conclusions?
