hi, ive got a major issue with my 5dr 1.2 carb mk1 vauxhall nova
fitted with a peiburg 1b1 and a twin pole distributor
came running with a new cambelt. i rebuilt the carb and now it wont run. it fires. not smoothly and then backfires agrresively throught the carb. im an apprentice technichian so ive checked and replaced most bits. ive replaced HT leads, plugs, dizzy cap, rotor arm and coil. the firing order is correct i think its one of two posibilitys. the advance and retard in the dizzy has gone slack and is throwing the timing out. or ive bought a crap pair of plugs. bosch super spark multi tipped ones
other things to consider. the carb isnt adjusted correctly now ive rebuilt it so thats not helping. could the valve timing have slipped? could it be the ignition module?
any and every bit of help would be much appreciated as im currently losing the will to live over it. just kidding, but its getting on my nerves. cheers in advance peeps :D
