I'm replacing coils and points on my 1956 25hp SeaKing and there's a "extra" wire that I think was connected to one of the points, but I'm not sure.<br /><br />The wire goes through the base of the power head and connects to a small "device" that is bolted to the frame with one bolt. The device has one electrical post with several nuts on it, and one rubber hose that connects to the block.<br /><br />There is nothing else connected to the device.<br /><br />What does the other end of that wire connect to under the flywheel?

Hi Tim<br /> The device in question is an over rev limiter. When cranckcase vacuume gets to a certain point it suck the diaphram in the device and grounds out one set of points. This limits RPMs to half of what they were. To answer your question that wire connects to one set of points at the same place the coil and condencer connect. Do not run without the vacuume rev limit working. these motors can have the tendancy to run away. All this is explained in detail in the manual you don't have.

Alcan,<br /><br />Thanks very much. Now I can put this thing back together before sundown :) <br /><br />In fact I do have a manual: Clymer E/J Outboard Shop Manual 1.5-125 1956-1972. I couldn't find that part though. The book has been very helpful, as has this forum.<br /><br />This page too http://www.maxrules.com/fixtuneitup.html <br /><br />Tim

Re: Help! Where does this wire go ('56 SeaKing)

Hi Tim<br /> Does your motor use the old presure tank fuel system? Have you had time to investigate the condition of the system? Sounds as you are doing a great job of making your motor sea worthy. With most OMC motors of this vintage, the tank/fuel system leaking causes a lot of greif. Not so much leaking fuel as leaking presure and not suppling fuel. Replacing the coils (which your doing) is another good thing. I feel that these systems are and can be depenable. The thing is they are 45-50 yrs old and need renewed.I can't wait to hear how well your motor runs. While I admit all these 50s model OMC motor tend to sneeze a bit once in a while when trolling. It shouldn't be often and it shouldn't be a bother. Proper adjustment of the low-speed needle should keep this to the min.

Re: Help! Where does this wire go ('56 SeaKing)

There's only one fuel connection to the tank so I don't think it uses the old pressure system. Is there a way to tell for sure?<br /><br />There IS a little fuel leakage under the carb. I haven't seen it leak, I can just see a gassy film on the bottom motor cover under the carb.<br /><br />The coils I replaced were in sad shape. They looked about twice as bad as these: http://www.maxrules.com/62threehp/plateprior.JPG <br /><br />I'm a little worried about clearance between the coil heels and flywheel, as it took me some tweaking with the coil bolts to get it far enough away so the flywheel would rotate freely. I hope they don't loosen up some day and cause a huge mess.<br /><br />I also replaced some of the rubber hoses (fuel and vacuum I think)<br /><br />Found out the installed spark plugs were incorrect too, so I replaced those.<br /><br />I'll try to start her up tomorrow, and if it still sounds bad I'll tackle the carburator. I just hope it doesn't run worse than before. :rolleyes:

Hi Tim <br />It sounds as you have a fuel pump system. The coils you show in the pic are the norm, unless resently replaced. You may as well remove and clean the carb before firing up. They are not very complecated. As for the coil laminations, I use the end of a steel rule as a strait edge. and push the coil laminations into position under slite tension, then tighten. Then check by rotating flywheel by hand. There is a locating ring for this job. I have never had one,and never really needed one. It would be nice though. Have confadence your motor is going to run like a swiss clock.

Re: Help! Where does this wire go ('56 SeaKing)

OK - Since you insisted I've begun to overhaul the carb. ;) <br /><br />It's all disassembled now, and it wasn't too dirty inside.<br /><br />I'm comparing the parts to the ilustrations in the shop manual, but there seems to be a discrepancy. One of the big needles does NOT have a point -- at all. It's basicaly the same dimensions as the other proper looking needle, but the last 3/4" narrow pointy part is gone completely. The tip is rounded and very smooth, and there is a VERY slight smooth nipple. <br /><br />Is that right, or is that my idleing problem?

Re: Help! Where does this wire go ('56 SeaKing)

tim,<br />wutz up ????? those needles are different for diff. carbs.some come to a point and some have a blunt end.usually the pointed one bend at the end because of over tighting.when u put screws back in --just snug em lightly and then back em out what ever the book tell u.if the needle point is obviously broken or bent u need a new one and usually comes in the carb kit which u can get at napa.where did u get your coils ???? i just rebuilt my 1960 seaking and bought new coils points and condenser on ebay for 36 bucks as i was the only bidder. so i'm waiting for them to arrive to see if this baby will run.oh yeah check the float which is probally why the gas leak. shake it to see if gas is in it and if so u need a new one.also check the adjustment of the float which is important.longest message i ever wrote being a 2 finger typer ha ha.good luck and i hope u took a compression check.tell us how it goes. steve b.

Hi Tim<br />That is correct. Your hi-speed needle has a very blunt taper. As far as I know needle valves will not come with any carb kit. Just blow out the low-speed circut real well. Make sure the float, floats and the float valve closes. Adjust float properly and make sure the main nozzel gasket is in place and in good shape. This gasket is a small flat washer-like gasket that seals between the main nozzle and the bowl.

> make sure the main nozzel gasket is in place <br /><br />I've installed a new float, gasket, and valve.<br /><br />The only gasket inside my carb is a plastic wasker-like gasket that gets screwed down by the needle valve which is controlled by the float.<br /><br />Is that correct?
