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