electrical or carb issue mmm

hello, odd one here, had for last couple months now, car starts a1 then great until i give it a little beans, goes fluffy, no idle then dies, tonite was last straw as had to get tow home, in past i left car for half hour but tonite worst ever, car a 68 barracuda,ive rewired so know electric good, ign a msd 6a run off points dizzy <msd will trigger from these fine> mech fuel pump, holly 750 vac sec 4 speed manual.msd blaster coil, now im getting tiny bubbles in clear filter, never given much concern as had these before,pump the gas pedal and you can see fuel squirt in primarys.car still real fluffy and not reacting to fuel input,coil does seem quite warm as mounted on carb inlet yet facing upright,changed condenser still same,put my multimeter on wires from msd to coil and no 12v yes does start and kinda run. bet you $20 ill go out there in mourning and she fire up run sweet...........till goes wobbly. ps the msd settup been on car last 12 months and not missed a beat.,,,.............just went on msd website quote"One common question in regards to MSD Ignition controls is &#8220;Why isn&#8217;t 12V power on the orange (COIL +) wire?&#8221;
The main reason 12V won&#8217;t be present at coil + is because your MSD ignition is a Capacitive Discharge Ignition... so aint that lol
