@rgrinder,Thank You, brother, Please ask bro, I really am at a dead end here, Yes fuel filter is clean, and is placed right before the fuel pump, The Distributor is a points type standard on the A12 the vacuum advance was broken since i bought the car about over a year now, now i have connected it, the vacuum is running fine, no leaks, I removed the Coil Resistor when replacing the coil this problem of engine bogging down was before on the earlier coil too..... The jets in the Carb are correct, rechecked them, the primary and secondary are in there place, the timing is 2 or 4 degrees retard, because when i advance it the engine jams, will check the points gap.. and spark plugs again, should i redo the timing after adjusting the gaps?... the old coil also was overheating and had a resistor with it??..
