starting an engine that has set for a while
 

I bought a 7.4 MPI over a year ago that I heard run before I got it and has been stored in my climate controled barn for the past year and half. I have it installed and am ready to start it. My question is should I do anything before I try, spray oil in the cylinders, anything to move the oil around? any help would be great Thanks Bman

Being in a climate controled shop should have helped a lot. You could spray in some oil just to help lube it. I would probably pull the plugs and wires off the distributor and spin it over until you get oil pressure. Then put plugs back in and fire it up.

Mine sat for a couple years, I pulled the distributor out and primed it with a drill before I fired it up.

Pull the dist and spin the oil pump. Put a couple squirts of 10W-30 in through the plug holes, (put the distributer back in first) spin the motor by hand a couple rotations to make sure it was not stuck or had a sticking point and then let the starter spin it a few more times before letting it start.
Like said, climate controlled storage has extended it storage "shelf life" time by a lot.

Might want to replace your impeller, if they sit, they crack.

Thats pretty much what I'd do. You really just need to pull the plugs and pull off the coil wire though.

I am in a similar situation, motor has not been run for a few months, stored inside, I plan on pulling the plugs, squirt a little oil in each hole, pull coil lead and turn the motor until I get oil to the top end. The one thing I am not sure about is, should I disconnect power to the electric fuel pump while doing this? I am thinking I will be "washing" the cylinders while priming the oil...??

Sorry to hijack but similar question......:party-smiley-004:

Amazingly, most engines make same oil pressure at crank speed as the they do at idle with plugs OUT.

Plugs in, it's much harder to make pressure at crank speed.

You can test that info by putting a manual gauge on it and trying it both ways.
