I dont know if at some point I inadvertently removed my distributor hose or it rotted off, but its gone regardless. Does it require ported vacuum or manifold vacuum. The info tag for my hose routing (on the fan shroud) is in such bad shape I cant read it any more. My Chiltons is useless it tells me to read the tag. Who makes the best service manuals? Hanes and Chiltons I find lacking a lot of information and good diagrams and/or pictures.
My S10 was a transition year. It has a carb and no computer. Rebuilt at 108,000 Kms now has 370,000 Km
Another point about setting the timing with a light does the hose have to be removed and plugged during the procedure? or am I thinking back to my Ford days?
