Hi when you did the trimming did you remove the vacuumed line to the dist. if it had one. it might just need a carb. adj, and when was the last-plugs-points-rotor-condenser-cap-wires. and is the choke hanging up on you. I would adj. the carb turn in the lil screw on the r/ side and go in till it almost stalls than back it out 1 1/2 turns or till it sounds good do the same to the left side ok  and check your fuel filter and check to see if the secondarrys are working. if you have vacuumed throw that out and get a manual set up for it
