timeing is easy to check,,but i have to agree on the vacume lines being done first,,seeins the spark advance is vacume operated,,i cant say for sure on amc engines<i am still a newbe to them,,but have 18 years turning wrentches under my belt> and please correct me if i'm wrong,,to check timeing one has to have a timeing light ,,after that its real easy,,for a check just look the spec up <underhood data plate> and unhook the vac advance <low on side of dist.>,
hook up the light find a clear spot to see the gague in the crank end <do a dry run with the engine off> and thats about it the light just hooks to battery for power and has an inductive pickup that goes on plug wire <#1>,,
