timming addvancement

geting ready to turn the fuel screw up on my 91 non turbo and wondering if it would be beneficial to twist the pump for advanced timming as well? if so how much? i was thinking i heard about two dimes width.

Depending upon engine performance. If its warn out advancing time will only make it smoke more. You can turn it up a little if its not smoking now. That and check when its cold and warm at idle and at speed to see if it performs the same.

most seem to be set a little retarded from optimum advance. usually a dimes width is about right. depends how much it rattles now. the marks on the ip are just a guide to get it started then properly time it. they are rarely correct. if you advance it and it doesn't rattle much more when the cold advance kicks in, its probably too far. if it has issues starting hot after adjustment, its probably too far as well.

There is a way to test the timing after adjustment. It involves push the advance arm in while it's idling. On how the engine reacts will tell ya if you got too much timing or not but I'm kinda brain dead right now cause the rest escapes me. Do a search and see what ya find.

As bigboytoys says. Push in on the advance lever with engine at idle. If the engine stumbles/fishbites a bites it's set properly. If the engine just slows a bit then it;s too far advanced, if the engine shakes or quites it's too far retarded. Oh and 185k miles is a lot for these db2 pumps.
