evinrude v6 200hp 1976, engine runs great but shuts off when i put it in gear, how do you adjust the idle? One person told me with the cable adjustment knobs and another told me to take a cotter key out and turn the plastic thing on the rod!
 
I've never owned an outboard that old, but I'm guessing its about the same as the 80s and up carb motas. On those, the idle is set by adjusting the idle stop screw on the carb linkage. Its the one that stops the throttle/timing arm when the throttle is closed- has a stop that rests on the motor. Then the cable length is then adjusted to slide on the arm and not pull either direction

I'd get a Seloc manual for that mota: http://www.selocmarine.com/product_detail.php?item=6
 
Got it. You take out a cotter key, then the pin, loosen nut on arm and turn the plastic thingamajiggy towards the bow until the metal whatchamacallit is line up with 2 marks it has conveniently there for that purpose. Thanks Checkmate friend!
 
NO, that is not how you adjust the idle, you turn the screw on the throttle arm in, thats it!

You adjust the synchronization of the spark and the carbs by setting the pick up timing at 6 btdc and then lining up the marks.

If you have to fudge the linkage to get the idle high enough then you have other issues with your engine.

Is this the same 76' 200 that was posted down on power before?
 
Your idle problem most likely is not from bad adjustment its from dirty jets in the carb.

Carbs just do not get out of adjustment, trash in carbs is what messes everything up.

It was low on power, cleaned all carbs and found missing gasket on top carb, power is good now and idle is good now gapped spark plugs to mechanic recommended setting and all seems good! Will ask about pickup timing, dont know enough about that but the marks were way off.
 
let me put one more thing out there. the motor idles great, when i run her she flies:surf:, the problem is when i go to put it in forward she shuts:brickwall: off getting over the hump into gear so i have to shift fast and give her gas which is not good when coming up to the dock. because she shuts off when shifting. the adjustment i made idled her up a tad, will that hurt anything?
 
when you do what you did you are just masking a problem it may run better but its not right.

Set the idle timing with the screw on the throttle arm at 6BTDC, at that point adjust what you just did so the marks align with a slight air gap at the roller, just so you can spin the roller, then, back the throttle screw off for idle speed, but it just seems you have carb problems, what gasket was missing? Theres only one in those carbs, you need to clean the carbs with engine tuner, as well as the jets, that stuff you mentioned really doesn't remove green gunk like tuner does, it will desolve it.
 
Hey Bill I really appreciate your posts and you are probably getting bored with this however here goes, My engine has 3 carbs, each carb has 2 gaskets, one up against the intake and one on the cover side all gaskets are in place now, I cleaned the 3 carbs more than once(until i got the gaskets right) with carb cleaner a friend had after completely taking them apart, jets and all... so my question is what in the world does 6BTDC mean, because when i find out I am going to do it!
 
Okay, I cleaned the carbs after totally taking them apart jets and all with carb cleaner a buddy had, I have 3 carbs each with 2 gaskets one against engine one on coverside, when i got the top inside gasket back on is when she started running correctly (I had misplaced it), I would really like to idle her up correctly and would certainly try if I could figure out what the heck 6BTDC means, going to google it now, thanks Bill!:confused:
 
Marine plug? I thought that went into the aft bottom so water would stay out, I didn't know there was such a thing as marine plugs, how about champion L77JC4's? They seem to work well.
 
They will work but from what I seen they foul quicker because of the 2 stroke. This could be part of your idle problem..
 
Those engines came with UL77V's, then there was a recommendation for L76V's both were surface gap plugs. For most of the old crossflows we later recommended L77JC4's for most of them, however, the 76 200 was not one of them, the early 200's had real tight heads and wouldn't use them in there, the trade off is surface gaps are colder and foul easier, so most people run the J Gaps anyway, I would run the J Gaps but always keep in mind, that thing gets premium fuel only.
