Carb issue?
If i barely hold the secondaries open i can get it in the idle circuit and vacuum becomes steady and jumps to 12" . I may try the method again but think i will need a holley or larger CFM carburetor. Thw larger butterflies supposedly allow more air around them and may allow me to get to the idle circuit with Timing around 20 degrees.
I can see logic both ways. I think that the right track is the idle air bleeds. I read a similar post when trying to adjust yesterday.
- I removed metering rod spings
- vacuum advance is disconnected
- secondaries are closing(i have not adjusted or did anything to hold them open
- installed fuel regulator and gauge adjust to steady 4psi. Floats checked no fuel entry and proper float levels
- idle mixture screws are currently adjusted 2 turn out from gently seated
- PVC is plumbed and in good working condition
- have the FBO mechanical lock out and spring kit
At 14 degrees timing motor fires right up and idles great, but rich with idle screw in past idle transfer slot. As i advance the timing and turn down thw idle screw i get to 22-24 degrees.
It will run idle easily at 800 to 850 rpm at as low as 16 degrees timing, but again not in the transfer slots.
I have drained and flipped the carb over and adjusted to a square on the idle transfer slot. With the idle screw that way i cannot add enough timing to get it to idle, but will try again tomorrow.
I also have rhe strip kit with all the different rods, jets, and springs to set up the carb later. I just cant seem to get it to run on the transfer slot.
