upallnight,
You are not listening, my expertise is in carburetors and distributors, in a computer controlled and "pack" system....ie: I retired in 1990, No computers, CAD was just being introduced in Architectural drawing....we used pencils and paper !
So my point is, I don't have a clue how any of this works...I can email, Google, Yelp, ebay, craigs list etc....WTF is android anyway.....
Isn't there a simple inexpensive OBD reader that will tell me what is wrong, so that when my mechanic says x%&5XX is kaput, I may have a clue what he is talking about
PS, I can probably still rebuild a Rochester Quadrajet carb ( if I can stop my hands from shaking)....remember what those were....if not .... it's a big 4 barrel carburetor that has ball bearings ans springs that "fly out" when you remove the top.....as me how I know....ever drop the mounting screw for a set of "points" down into the bottom of a distributor and have to remove it to get the screw out, and not knowing enough to line up the gear before pulling it out, so you can get the"timing" right??
No to be a wise guy, it's just that technology has passed me by....a long time ago...
I'm a PRE ANALOG GUY living in a DIGITAL AGE. (have pity)
