J restrictor Plate

[T Chance]

Is there an easy way to get to the "hard to get to" carburetor nut on an OMC A motor to put in and/or remove a J restrictor plate?

you need to remove the large bolt holding the rope pulley gear. screw the bolt into the gear to hold it so that the spring stays in place. Then loosen the nuts and slip in the restrictor. Get someone to show you how.

Thanks I think I understand. One more question. Gaskets. I slipped it in between the carb and the gasket. Do I need another gasket between it and the carberator?

[bill boyes]

Yes, But glue the gasket onto the restrictor.

Quick Tip

Keep a few wing nuts in your rigging tool kit. Fast and easy. Bam !!

[bill boyes]

Thats' how. Just loosen the Carb nuts and slip the restrictor is or out. I have seen it done in less than 5 minutes.

Thanks everybody. There is going to be a real grateful 3rd generation boat racer happy for the help in 2 weeks when she goes for her first boat ride in Pell Lake, Wisconsin.

It is best to have the "special wrench" that OMC or APBA used to supply years ago. It is box end/open end 7/16. The wrench is very thin thickness wise and the box end is 12 point and small like an automotive ignition wrench. The ones I've had were Craftsmen. Makes it so much easier. You could grind a bigger wrench down, make sure the box end is 12 point. Also the wing nut trick is a good one preventing the starter from doing the Jack in the box all over the place.

Back in 88 when the restricter was first used, I welded an open end head to the end of a bolt at 90 degrees to loosen and tighten the bolt without taking off the starter. I also had a later version that was welded to the end of a quarter inch drive socket extension bar and could drive it with a socket wrench which was easier than using the bolt. It was basically the same as a crows foot setup, but made small enough to do the trick. At first, I used a notched gasket that slipped in with the plate and later, when it was deemed legal, just kept two gaskets behind the carb and slipped the plate between them. Later versions also had a handle with a loop that the bolt/bar rotated in to make directing the wrench easy. Made these for several people back then.

PS - We could put the plate in in less than two minutes.
