i have 2 999 fire engines, neither will idle. i have tried running them with points, electronic ignition, cleaned carb, replaced carb, replaced ignition advance,ajusted ignition timing, cleaned and set pugs, switched rotor arm and distributor, inspected cam, adjusted cam timing, fited an electric fuel pump, cut the end of my solenoid and used bad language. the symptom remains more or less the same engine will run with lots of revs or full choke. which makes me think its a fuel problem. next i will replace my ht leads, pray for divine intervention or look for a diesel engine i can slap in there
