I just recently posted a new topic on my woes of solex and timing, but soon i made a discovery that my vacuum box isnt functioning correctly as i sucked hard on the tube and it didnt move and i couldnt suck air through it so it might be clogged or something? The pushrod i tried to push into the diaphragm but it wouldnt budge too much and with ease and so thats where im at, i just need the vac box for the distributor listed which as im not surprised is going to be a needle in a haystack
