41chevy Posted November 9, 2018 Share Posted November 9, 2018 Looks well kept. If I needed another truck I'd consider it in a heart beat.

Quickfarms Posted November 17, 2018 Author Share Posted November 17, 2018 That is the older small ones. terry:MackLogo: Great, I still need a small M I made progress with the DMV today. In and out in 30 minutes with a temporary registration, Sacramento will mail the historic plates to me soon. Now to reinstall the ignition switch. Is it normal for a truck with an air ride cab to have the exhaust stack bolted to the cab? Is it normal for there to be a band clamp connecting the flex pipe to the exhaust pipe under the cab? I also need to fix the air ride seat, its loosing pressure when I sit on it Quote Link to comment https://www.bigmacktrucks.com/topic/54779-1985-rs688lst/#findComment-409531 Share on other sites More sharing options...

Popular Post Quickfarms Posted December 6, 2018 Author Popular Post Share Posted December 6, 2018 My painter stoped by this week and was able to get the decals off of the drivers door without much paint damage The passenger door already had some paint damage to it The decal removal did more paint damage, the primer is where it went to bare metal Both doors will get painted as soon as it stops raining until then the Mack is resting comfortably with some new friends Now I have to deal with the hard starting issue. The truck cranks for a long time before it lights off. It acts like it is losing its prime. Any thoughts on where to start looking? 3 Quote Link to comment https://www.bigmacktrucks.com/topic/54779-1985-rs688lst/#findComment-410786 Share on other sites More sharing options...
terry Posted December 6, 2018 Share Posted December 6, 2018 (edited) Check all return lines from injectors, also the fuel delivery pump has two small plastic check valves, if they are not sealing it will lose it's prime. terry I suppose you should check all fuel lines!
