I have built a fresh 2.0 and borrowed a set of weber 40s to get her running, broken-in etc....
I bought a new single vacuum distributor with the flame thrower 3 module inside. Also bought the Petronix coil. I built up oil pressure, then connected the gas lines, fuel pump, and coil. Tach and timing light too. After a few tries, she started. As expected running very ruff. Back-firing thru the carbs. I loosened the distributor and tried to make some adjustments. That seemed to help the back-firing a bit, but not totally. I got the idle timing to what looks like 7 btdc, but it is tuff to work everything without a helper. I know next to nothing about these carbs, and about the same amount to tune them enough to bench run the engine, but I am looking into that. Any help would be appreciated on the carbs. I got it idling, again, very ruff. So I wanted to do the cam break in, so I rev'd it up to about 3000 and held there. Maybe a minute and the revs dropped and I had to putz with the accelerator to keep her going. Again up to 3000, same thing revs dropped. I have a note in to my distributor vendor about how this "rev limiter" on this module works. So three things here. She is still running ruff, back-firing etc...and there is the high rev cut-off. Lastly the carbs, any quick checks or adjustments there? Any thoughts or suggestions? |

I'll add that if your linkage moves at all when you put it back on, then you don't have the linkage correctly set up. Drop links have to be exactly the same length and both on the idle stop screw
