i just got a sweet 85 turbo, i think the last year of the small headlights, and i am having a tough go at getting it to start. it sat for about a year. i changed the fuel filter (expensive!) and the old one really had a lot of dirty gas in it. new battery helps it to crank just great, and every once in a while it really almost grabs on. i have planned to change the oil, plugs, and drain and refill the gasoline. where else could i plan to investigate? maybe the fuel pump? i think the internal tank pump is new, but the other may be the culprit. any help appreciated.
