Zephyr, no doubt a little thing to you "old timers" but got distributor on and hooked up today (sunday). wife gave me the day off. have to hook up vacumm advance line then I can roll engine a few times heads off then go for startup... (if things go well). Wanted distributor on before rolling becase I wasn't sure being off would damage anything.. on close inspection spark wires not new but all checked ok.. will have to replace sometime soon. Now have some experience and from what I can tell taking wole asembley off may be the way to go. The best way seems wire distributor install and thread back through conduit.
