Really Confused

[boatingbob]

I finally got my Seloc manual and I have just become more confused. I'm tryiong to adjust my throttle linkage so I get full throttle and the motor will idle right. I've been reading and reading but I just have no clue what they are talking about. I have a 1962 40hp johnson.

any help would be great

Re: Really Confused

Oh, I know what you mean. You're working on link & sync, around page 5-30? If so, have a look at my alternative explanation:

Look most of the way down at the second set of pics.

After you've got that squared away, set the linkage that runs between the throttle arm and the cam roller follower. It should be adjusted so that it pushes the cam roller follower off of the cam after the armature plate stops turning.

Make sense?

Re: Really Confused

That engine has what was called cruise control. It has a heavy wire link that goes from the throttle tower shaft to the carb linkage, When you throttle back, the ignition stay's at full advance and the carb goes about a quarter closed. This was a fuel economey measure, if there was such a thing in 1962. On this wire link, and next to the throttle shaft is a brass keeper with two lock screw's. Unlock the brass keeper, advance the engine to full throttle, push the wire link to full throttle , push the brass keeper up against the throttle shaft link, and tighten the keeper screws'. On the Ign., or stator advance plate is a brass cam follower. As it start's to advance there are two indentation's. The rubber roller on the carb linkage should start to open the carb when center between these two mark's. This is adjusted with the carb throttle shaft, or link screw. Here is a case for an OEM manual.

Do I need to remove the fly wheel to do the Link & Sync?

Re: Really Confused

No, all adjustments are made with the flywheel in place.

I'll try to figure this all out tomorrow. thanks for the help

O.K. getting more confused. I'll post pics.

Re: Really Confused

is it possible for someone to dumb this process down in step by step precedures? here are some pics.

One of these days I'm going to get my wife's camera and do some posting too.

Re: Really Confused

Pic. #1, This is the cruise control, and full throttle control rod. You can loosen the brass keeper as the first step.
Pic. #2, This is the throttle cam follwer. The groove in the rubber roller is from wear, it won't hurt any thing. The loose play in the throttle rod link in the same pic. is normal, and also won't hurt anything.
Pic. #3 This link control's the carb. throttle plate, This will be your first adjustment. Advance the throttle untill the rubber roller is centered with the mark "marks" on the brass throttle came. The carb. plate should just start to open. If it open's early, or late, loosen the set screw on the throole plate of the carb, and adjust the link so that the rubber roller is in sync. That's it for the front part of the linkage.
Now rotate the throttle to full advance, and hold it there. you can do this with the remote control if it is hooked up.Now go back to the brass keeper in pic. #1. Push the throttle rod all the way forward until it stop's. This will open the carb. plate all the way. Push the brass keeper back against the throttle arm, and lock it with the set screw. That is it for the linkage adjustment's. There is no timing adjustment on this engine. That is taken care of when the point's are set.
Pic. #4 That link lock's out the rewind starter when the throttle is advanced to far. It is a safety feature.

Re: Really Confused

I hate to further muddy the waters by disagreeing when we're trying to clarify things, but this statement is incorrect for a 40hp:

Advance the throttle untill the rubber roller is centered with the mark "marks" on the brass throttle came. The carb. plate should just start to open.

The rubber roller is not supposed to be centred on the mark when the carb begins to open, but rather the mark should be on the end of the manifold pointer:

Thanks for the clarification the Seloc Manual is so hard to understand. I'll do the adjustments tonight.

Re: Really Confused

O.k. here is what I did:

1 loosend the brass lock on the throttle arm
2 advanced the cam to just before the mark and pointer lined up
3 loosened the throttle linkage
4 tightened the throttle linkage
5 advanced cam and watched for movement.
6 looked good
7 put motor in gear
8 held open throttle linkage
9 advanced stator to WOT position
10 butted brass locker to throttle control arm and tightened.

Does that sound right?

Re: Really Confused

Paul: Thank's for the help, I forgot about that manifold pointer. Bob, sound's like you got it.

Cool, once I get the boat back together I'll slap my fancy new Tiny Tach on and head to the lake. then I can check out my WOT RPM and top speed. maybe even break my 28 mph previous peak speed.
