    {CARB SWAP} MSD is in, tuned the carb..

    Ok, I got home today, and my nice shiney new MSD 6AL got here. So not wasting any time, I went and installed it. Very good instructions, and was able to make a pretty nice instalation...

    I love it!

    Heres a pic of the duraspark module that survived multiple overheating...it ruptured the silicone, and the epoxy started to melt! :hairrais:

    Here is the install. This weekend i'm going to install me new plug wires, and my chrome valve covers...and clean up the motor some, and possibly start on the WIRING AUDIT, lol....

    Then I spent the rest of the time tuning the carb, to get the optimal setup...I got the thing to idle as smooth as glass, but it still loads up momentarily on any good amount of acceleration.

    So my theory is the accelerator pump needs adjustment. im gonna make it so that it doesnt unload all that fuel into the carb UNLESS I FLOOR IT.

    But thats all for tommarow. I'm whupped!

      Glad to see you are making progress!!
      Where is your fuel pressure regulator in that picture? Your pressure guage needs to be in between your filter and the carb or you will have no clue how much fuel pressure is feeding the carb.
      "Loading up" is making an assumption. Are you referring to stumbling or hesitating?

          Well Ed, I removed that filter, cause I think its a little bit overkill, lol....

          And it seems to hesitate for a second when I punch it, or accelerate a good deal...I'm gonna mess with it today, and let everyone know how it goes.

          Im going to remove the rod for the accel pump, taking it out of the circuit, and see what happens, just for an expiriment...

            I am talking about the filter you are using for your return.

                    The front bowl vent is capped off in the picture, maybe leave it open to the atmosphere.

                    Hesistation when you give it gas might be a misadjusted accellerator pump circuit.

                    That is your initial timing at?

                      Yeah, I capped off the vent. Should I uncap it?

                      Yeah I think the accelerator pump is what I think is causing my problem...

                      And my base timing is set at 14 BTDC...

                            If you disconnect the accel pump totally it will hesitate and possibly pop back thru the carby when you stomp it.
