bruno:
placed an order for a new carb kit from you, with some extra gaskets incase i rip one of them while figuring this out. i also put a note about distributor springs for the centrifugal advance. haven’t got there yet, but i assume these are original. but not knowing for sure, i’d rather get some good new ones to be sure. i will try to figure out the centrifugal advance numbers tomorrow, and i’ll post them here if i can.

pulled carb today, luckily the gaskets came apart easily!! used a .030” mig wire to poke through the idle tubes, and blew out the passage as best as possible. i didn’t pull the tubes, hoping the poke and air would dislodge anything in there. i removed the idle screws while doing this.
float height is set at 9/32”, not sure where it should be, as i no longer have the rebuild instructions. i’ll leave it there for now. throttle plates look good, a tiny bit of light around the primaries, but i think it’s okay? secondaries are excellent, no light. will put it back together and see what happens.
cliff, i’ll still take that kit i ordered just to have the gaskets for future use. thx.

fired right back up after putting carb back on. think i misread vacuum gauge last test, as i’ve got 16.5” of vacuum know. think i was thinking the needle moved the other way!!
i also just checked the pcv valve, and it is sucking air at idle. just for clarification, that should not be the case right? it should only be operational at part throttle? it it hooked to manifold vacuum on front of carb.
still have almost no effect with mixture screws, and can’t see any nozzle drip.

can’t seem to upload pics from my iphone. says it won’t accept that file type, and i don’t know how to change it!!
