Did yours (with the bad coil) run fine at higher speeds? I'm working on a car today that bogs down taking off from idle, but runs good otherwise.

Great news, I also learned something new, wil also remember the coil in future

problem solved. bad ignition coil. thanks for the suggestions!

So it had the same symptoms with the original Hitachi? And now with a Weber it does the same thing?

Check your wiring inside distributor as well. Had that once, took a while to find it as it seems to be intermittend.

i dont think its a fuel issue, i recently replaced all the lines, and put a new filter, and a weber 32/36.
im thinking it might be a bad coil, im going to try the one from my dad's 620 tommorow.

Hi M,
It seems to be a common issue, (my personal opinion)as my A15 wil run fine then out of nowhere it will start to stutter as if some blockage in the fuel line. I have cleaned my fueltank and fuel lines, but it still persisted. In the process of overhauling the engine, dropping CR and fitting weber 36 dcd 7 in the meanwhile. What seemed to help at stages was to let the revs pick up to about 5000rpm a couple of times( as if to clear its throat) then mine went fine again for 100-150 km. really odd! good luck

hello gents,
ive been having some problems with my A15 for a while now and its pissing me off. the car runs fine when its cold, but after it warms up, it will bog down at low RPMs, and if i try to take off from idle, and it will turn off at idle if i let it sit. any suggestions on what to dd, or check?
thanks in advance
