i think the balancer and key holding it in place are fine.the dist. seems to be working fine. but i haven't checked the vacum unit on it.it seems to have only two lines.the crankcase vent where i take the vacum reading and the metal line going to dist. both were hooked up when i tested timing.i will try to see which one i need to unhook while i take reading.also how can i test the unit on the dist. thanks for all the info., hoggyrubber
