2.0 Pinto Mis Fire

[Derzo 1]

Hi everyone fitted a vacuumless dizzy and still got a bit of a mis-fire mid range, running twin forty webers timing set at 8 tdc any ideas anyone.

Might be worth getting a timing light on it and running up through the rev range. A guy called Dave Andrews has a great write up about where you should see what advance, it could be that the advance curve in the new dizzy is wrong for your particular setup, usually it's a case of replacing one of the internal springs with a stronger or weaker one to get the curve right.

Fit the strobe to each HT lead in turn.

Youre not looking for timing but to see if you can spot which cylinder is missing.

IThat will make it easier to isolate the fault.

If all 4 cylinders show even firing, its a fuel problem.
