15 HP Rude. Warm up lever won't engage camfollower

[Woodbinekeith]

The throttle/shift levers seem to be set right; however when the warm up lever is engaged, it gets "stuck" on the flywheel mechanism before it engages the cam follower.

Is it possible to jury-rig a manual push/pull lever to get around this.

I would predict a bad ending to any kind of self-engineered solution to this problem, due to the "law of unintended consequences".

It's sticking because of dirt, or corrosion, or a broken part up in there, or a misadjustment.......

As a general rule of thumb, in my experience, your motor will last a long, long time only if you fix what breaks, when it breaks.

you can view schematic diagrams online at www.shop.evinrude.com click on 'electronic parts catalogues' and I highly recommend a service manual for your motor. Will pay for itself many times over.

Fix the problem, or down the road you will be fixing a problem like this.

$10 Shift Lockout Lever

Cause $400 worth of gears to go bad.

what yr motor is it.I cant understand what your referring to.Could you be talking about the roller not following the cam under the flywheel.If so,does the cam have a piece broken off""some have an adjusting screw attached and the plastic can break off.Hope I can help with more info

The motor is 1990. I don't think there is a missing piece under the flywheel that the cam follower moves along as when put in gear, the cam follower will move to full acceleration position.
When pushed into reverse, the cam follower moves along the path and will increase gas to the carb.

In neutral and pulling up on the warm up lever, it will move only a short distance then the fly wheel buts up against a fairly large plastic part - the part with the notches in it that holds the gear in forward or reverse. I've tried adjusting the cable lengths of throttle/shift and when the warm up lever does go up all the way, then the throttle/shift don't seem to function properly.

If I hold the cam follower down by hand, the engine will start fine so it must have to do with the "sync" - very frustrating. If I release the cam follower once the engine is started, it sits straight up and with not enough pressure on the throttle link to keep the gas going the motor dies.

I replaced that little piece of plastic with the screw on the cam follower. I learned the hard way that this is a very fragile item.

It's going to be tough for anyone to get a good idea of your problem without us all speaking the same language. "the part with the notches in it" has a name, but I don't know what it is. You know what they say, "he who tries to repair his own outboard without a manual has a fool for a mechanic."

I wounder if you are talking about the interlock that keeps you from overreving the engine in neutral? When you put the engine in forward or reverse the interlock moves out of the way and allows the throttle to advance.

If you have to hold down on the cam roller attached to carb to get the engine to start and run, you need to do a link and synk to adjust it properly.

Re: 15 HP Rude. Warm up lever won't engage camfollower

Yes, the piece I couldn't fine the name for sounds like the interlock you spoke of. It does move out of the way when the throttle lever is advanced or pulled back into reverse. When shift is in neutral - the warm up lever is blocked from advancing. Does a "link & sync involve adjusting the throttle/shift cables or does it have to do with the carburetor linkage?

Re: 15 HP Rude. Warm up lever won't engage camfollower

It deals wit setting the timing to the carb linkage. Do you have a factory manual manual for your engine, it would show you how to do this.

The cold start lever does not raise the throttle so much, but it advances the timing to better start a cold engine.

When was the last time your engine had a good tune up? May be time to overhaul the carb, low speed circut may have a bit of trash in it.

It's not a warm up lever its so you don't start your motor in gear.
My 25hp has a screw with a large slot with a nut on the back side of it that is located right where your talking about. Loosen up the nut and then adjust it with a screwdriver in or out then tighten up the nut.

Re: 15 HP Rude. Warm up lever won't engage camfollower

I don't have a manual - and the point made above is well taken I'm trying to get it ready for sale but will try to get a manual. I took it into a shop for a $400 job - starter and "get it ready for the water" and assumed it was done properly. The boat has been sitting for two summers so there may have to be something done with the carb.

Thanks so much for your help.

Re: 15 HP Rude. Warm up lever won't engage camfollower

i understand a bit more now,your throttle is supposed to lock up like that so as said you dont over rpm the engine,especially when shifting,your problem is clear now,your carb and/or fuel system have become varnished from sitting,if you service the carb and flush fuel lines of old fuel,your engine will perform as it should
