1990 Evinrude 60 .... HELP!!! I've done all I know to do to make this thing open up!

[RobF1970]

Model TE60TLESM. To start with, motor was running fine up until a couple weeks ago. Then, what happened was I was going at WOT and it all of a sudden gradually lost power until it quit and wouldn't restart. First thing I did was clean all 3 carbs. Then I replaced all fuel hoses from the tank to the carbs. Next, I found out that woodruff (shear) key on crank/flywheel was broken making it out of time. So, replaced that, and used Joe Reeves method to retime it. Now, sitting in the yard on muffs, the motor runs fine. Put it in the water and its hard to start (I usually have to remove the cover and play with it to get the initial start up). I have upped the idle rpms to compensate for the back pressure of being in the water. Anyway, from around 1/2 throttle to WOT, it just bogs down. Oh, and I did check compression on all 3. 105, 110, & 115 across. Rigged spark tester for the Joe Reeves method and shoots blue 7/16 spark across gap. What the hell do I do now?????? Killing me.

magnet/s on flywheel loose??? link and sync..also you should do a decarb and see if you can get that 105 up some.

Magnets are all tight. Now link & sync, I'm not sure about, but I don't have a manual, and I was hoping to find that information on here in a secret file or something. Question: If my WOT timing is correct, do I need to set idle timing.... and if so, what should it be set at?? What I'm doing as far as link & sink goes is adjusting cam follower where it just touches the carb roller. Butterflies barely open, and I mean barely. I'm thinking maybe the set screws on the spark advance or something is off. Does anyone have pics or measurements that I can see/use to get these set screws in the right place???

Did you torque the flywheel down to the proper torque with a torque wrench, making sure the crank and flywheel tapers are clean and dry? If not, the key has probably broken and the fywheel has slipped, making the timing off a little bit.

Check and see if any of the lock nuts are loose on your timing stops. It's very unlikely that they are, but.....
If the nuts that lock the timing stops in place are tight, I wouldn't concern myself with timing yet. Besides, you get total advance of spark after about 1/2 throttle. It shouldn't make that much difference as long as it's not getting too much timing advance.
Take off the cover and air silencer and take the motor for a test run. Does it run fine with the cowl off? Maybe an exhaust leak into cowl.
If it still runs like poo, mix up a spray bottle of 50:1 fuel/oil mix and have a helper squirt some fuel into the carb throats while you're having the bogging problem. Does it immediately bog? If so---spark or timing problem is likely. Does it momentarily pick up rpm's? If so, fuel problem such as clogged filter, bad pickup tube in tank, tank not venting properly, dirty high speed jets in carb, kinked fuel lines, bad fuel pump, etc.
Good luck and welcome to the forum,
JBJ

Sounds to me you have the ignition system covered. That leaves fuel, air, or water intrusion. How do your plugs look after a run? When you cleaned your carbs, did you remove the welch plugs and clean all the passages under them? Are the venturi tubes solidly in place with no cracks or partial pluggage? When you had the carbs off, did you check out the reeds? Fuel tank clean and pickup tube ok and the screen on the end not partially plugged? Just a few items that crossed my mind....

Yes, flywheel is torqued to about 80 lbs. as of today when I replaced the shear key. And, double-checked the torque after running the motor on muffs. Checked WOT timing again (Joe Reeves Method) afterwards, and still on 19 degrees btdc. (That's a new question I have...... On the breather, it says 19 degrees btc, but I've read on many threads to set the WOT timing to 4 degrees less than prescribed.... so... Did I need to set the timing at 15 Degrees or what??). And it doesn't matter whether the cowl is on or off. It still runs like s*it at 1/2 to full. Tried it both ways because I thought that the air mixture would be to lean or too rich, depending on whether the cowl was on or off.

Plugs look normal. Have checked them over and over again. When I cleaned the carbs, I cleaned everything, and I dont mean just carb cleaner and blowing out - I mean removing jets, and everything doing a thorough job. As a matter of fact twice that I cleaned the carbs. Now, I did not check out the reeds, but I guess thats the ONLY thing that I haven't checked out on the entire upper engine. Maybe thats the problem, I don't know.

Well, one thing you said rang a bell..... momentarily pick up rpm's. Yes, that's what it does during the "bogging-in". Hard to describe in words, but I'll try... It does this if you can imagine the engine running: "Ehh - ohh, ehh-ohhh!! (in and out). That may sound stupid, but that's what it sounds like literally!

Hmmm,
The engine is surging. It still could be electrical or fuel related. If fuel related, most of my surging problems were due to vacuum leaks somewhere. Almost positively the reeds are not the problem. Reeds don't do much at high throttle, and problems due to reeds usually result in problems at idle. I wouldn't worry with them.
I'm thinking you may have a bad electrical component that's causing intermittent spark. Problem is, I don't know how to tell you to look for it. I believe I've reached the extent of my ability to help. I'd still have a helper spray some fuel in the carb throats at wide open throttle. You could at least eliminate a fuel problem with that test and stick to electricals.
Good luck,
JBJ

when setting the WOT timing by the Reeves method you should subtract 4 degrees, so yes set it at 15 degrees not 19..the double check it running down the river, hold on tight. check fuel pump and filters, fuel lines and connections, try pumping your bulb while running and see if it helps any.

Re: 1990 Evinrude 60 .... HELP!!! I've done all I know to do to make this thing open

Now I'm thinking fuel problem again. Are the high speed jets the one in the bottom of the bowl under the floats??

#14 in the pic. You can leave the carbs on, and use a strand of copper electric wire and poke them out once you remove the screw plug in front of them. A shot of carb cleaner through a straw helps also.

Thanks Lieu... I'm going out to work on it again right now.

Re: 1990 Evinrude 60 .... HELP!!! I've done all I know to do to make this thing open

Lieu, just got back from the lake. A little better, but still no cookie. I stopped in the middle of the lake and felt of the bulb from tank and it wasn't tight, so I pumped it up and it seemed to run a little better. I haven't had anyone to go out with me on the lake to help, so it's kind of difficult to do it on my on. But anyway, I might have mentioned it above, but the vro has been bypassed. Maybe the fuel pump is weak. I was thinking of putting an in-line pump in, or, getting one that'll work from evinrude. If so, what pump do I need to get from Evinrude????

Re: 1990 Evinrude 60 .... HELP!!! I've done all I know to do to make this thing open

You could just rebuild the fuel side of the pump, and disconnect the VRO. Here is a link to disconnect the VRO.http://forums.iboats.com/showthread.php?t=388154

Re: 1990 Evinrude 60 .... HELP!!! I've done all I know to do to make this thing open

going to get an in-line pump from autozone (universal - 4 to 9 psi). Will that be sufficient?

Re: 1990 Evinrude 60 .... HELP!!! I've done all I know to do to make this thing open

The pressure range would probably work, but you don't want to install an electric fuel pump on your outboard, could be dangerous.

Many people here wont agree with going electric. They could be a serious fire hazard.

you can get the old style pump for your motor..

O.K. what part # would that pump be if you know??
