    52 panhead finally starting

    Sooo, I have not posted in a bit. I stepped away from the bike then came back and started over : new points plugs condenser, wires, I retimed I reinstalled carb and pressure tested pressure tested. I had been reading that they often have their own personal starting procedure, so I experimented with different combinations of primer kicks, squirts etc and I found the magic combination. It now starts regularly on the first official kick. I even took it for a quick ride, very fast and smooth! I suspect a combination of 65 years of fuckery (i think farmall made that word up) , neglect and my unfamiliarity.
    Now fine tuning it and will give it back to the owner.
    However, It won’t restart regularly when warm. I suspect there is supposed to be a phenolic block/gasket thing betwixt the manifold and carb. What do you guys think? I called s and s they “thought” I need it. When it cools off around here ( don’t feel like kicking today) I will start the bike to see how much heat is getting to the carb.
    If I get a phenolic block, where does it go in? Between the spacer and manifold or between the spacer and carb? Or do I need it?
    As far as the low compression numbers, I’ll have to borrow the tester again.
    Thanks guys!

    yes, you'd need a carb insulating block.
    it goes between the carb and the manifold.

      Every bike has its own ritual, for my 56 I cannot touch the throttle once it is even a little warmed up. Just retard the timing and give her a kick.

      And yes I have the insulating block

        Just wanted to say.... An insulation block isn't a fix all do all...... Timing and float level is crucial....

        My Pan starts first time all the time and I don't have a block at all.......

          If it's much above stock I pitch the phenolic spacers and make one out of plywood.

            As I said, I can get it to start cold on the first kick after the ritual. I am having trouble restarting it when it’s warm. To restart it, I have to kick it over 9 times with the throttle open. Then it will start.
            So how do you seal a phenolic spacer? I assume tha I take the oring off the carb, right?
            As far as timing , I think it’s right. I will check the float level. Thanks

              What you need to do is find out why it's flooding????? I bet your float level is to high.........

              An insulator block won't help you I'll bet.........

                Tattooo, I rechecked the float level and is was fine per s and s specs. When attempting to restart, I was giving it throttle. I stopped throttling it and it starts warm now!!! All part of the personality of the bike.....
                I told the owner that it is ready . Again, thanks for all youse guys help with this.
                On to a new project....

                  My first question was, I asked you to figure out what was flooding it?????? Thanks for telling us......
