Zetec Ignition
I finally have my pinto to zetec conversion complete, and it runs.
I have what is apparently the usual 'occasional' backfire on start-up, as i have a older style zetec silvertop which suffered from
sticking valves, but once it starts (and it starts with no problem) it ticks over really smoothly.
I am using a weber 32/36 dgas carb on one of those banger conversion plates, with a ESC ingnition module (the one with the red insert).
the only grumble is when i give it some throttle, the car hesitates before it revs (almost like a cough, but without the cough) once it catches up
with itself, its fine. its almost as if the timing is slightly out!!!!
generally the enigne pulls like a train ( i replaced a 1600 pinto with a 1600 zetec) and is a million times smoother than my old pinto, so am very
happy.
any ideas where i could look for the cause of the issue.
Cheers,
B

I had a pair od 40's on mine and it too had a little bit of hesitation on the 40's it is something to do with the progression holes in the
carbs. I used EDIS and a GEMS ECU so not a problem with setting the ignition timing
Life is like a bowl of fruit, funny how all the weird looking ones are left alone

Its more likely to be the carb than the ignition, what is the carb from and did you jet it to suit the zetec?.
