The brain is NEVER bad.
pretty sure its happened once or twice in the past.
like I said, most issues can be sourced back to a faulty sensor, bad ground, or missing bits :lol:
in some cases, you may have a hard time finding these bits.
if your absolutly set on keeping the car 100% original, by all means, have someone go over it for you. Or save a head ache at the end of the day and convert it. Esspecialy sinse the price of a fuel pump for one of these is equal to the cost of a carb kit
