Also some more info :
I have tried to adjust the timing by turning the distributor both ways and still no change. I am
running a mechanical fuel pump. I am waiting for my fitting to come in so I can install a gauge and see my pressure. My carb has sight glasses so I can see the float levels and they are set to just below half way. Right now I have the card choke set to be closed when starting. I have tried to adjust the idle throttle screw from full closed to slightly open with no change. My issue is I am not sure if it’s a timing issue or fuel issue. Once I pulled the plugs and reset the timing the engine fires right up but then dies a few seconds later. I talked to the engine builder and they told me that I should have around 14 inches of vacuum at idle. The timing should be 13 initial and 36 total. Not sure if it’s running to rich and flooding the cylinders, when I bore scope number one I have a little fluid built up in the corner of the cylinder wall on top of the piston but I don’t know if that’s oil or fuel. I am assuming it’s fuel because the plug is wet and smells like fuel not oil. I set the idle mix screws to 1-1/4 turn out from stop which is even leaner then what it comes from the factory. I was told that the engine parred with this trans should run rich but I have a feeling it’s too rich but I don’t know how to find that out or what to look for.
