i had a 78 aspen given to me by my boss. its an S.E. package. its been sitting for about 2 years when i fired it up.

heres the problem: he told me the chain went bad so he replaced it. after getting it back together it run real rough. he tears it down and parks it. this has like 3 lean burn boxes in the trunk plus the one on it so i dont know which is the right one.

after 2 years i know the gas is bad but what else could make it run real bad. i have timing as close as possible but havent checked hoses. it runs ok with a rough idle but as soon as you put it in gear it acts like i has no power.

Damn man! I wish I had your boss. Mine gave me a fairly clean 90 Sable wagon with a bad tranny thats been sitting for two years. You know what hell I'm living trying to get a front wheel drive electronic tranny out of it is???

The problem can be within the lean burn. You can rid yourself of it and put in a better ignition system. Replace the fuel pump and filter. Get rid of all of the bad gas or dilute it with clean gas.

i would start by looking at that dist .and then probably changing that out . its fairly easy to convert it to a non lean burn

It sounds like he installed the timing chain incorrectly. That would explain why it ran bad after he changed it, and why it has no power.

My thinking as well. Especially since I have had two timing sets with the dots stamped a tooth off. If this is the case and he just lined the dots up when he replaced the timing set, the cam and crank are out of phase with one another.
