Pull chord? Perhaps it is playing the wrong notes?
If it went overboard, is it now the lost chord?

Thanks for correcting my spelling , it was a very helpful reply .
Ive managed to get the pull cord on and it turns the flywheel but ive only managed to get a small amount of cord on .If i turn the fly wheel it winds it in but just pulls out again without turning over the outboard untill the last foot when it engages . The lower part of the assembly ( the part the flywheel turns over ) has two notches in it and a groove that looks like it fits the cord but i cant see how to use it /forums/images/graemlins/confused.gif Still at least i got the engine started today /forums/images/graemlins/smile.gif

Glad you liked it! The only outboard I ever looked at internally had a cord starter just like the one on a lawnmower. There was a spring (like a clock spring) which re-wound the cord. To replace the cord you would need to fully wind the spring (by turning the pulley), then attach the cord to the pulley, so that the spring winds it up for you. When you pull, a fairly crude clutch engages the pulley with the engine. If you dont have the spring wound up it will not retract the cord, and it might also fail to operate the clutch . I am not familiar with your engine, which is why I hoped someone else would respond with the correct proceedure, but I suspect all these devices work pretty much the same way

I don't know the engine but I would assume you have a starter mechanism that is located beside the engine, rather than the type mounted on top of the flywheel. This then engages with a ring gear around the periphery of the flywheel via a bendix like cog similar to the way in which the old inertia type starter motors engaged.

I have not had to replace the cord on one of these yet although I have on the other type. If it is anything like my 'rude you have to wind up the spring in the unit by turning it in the direction in which it will normally turn when the cord is pulled (almost certainly counterclockwise). You will need to wind it almost but not quite as far as it will go. The thing will keep wanting to engage with the flywheel as you do this so you will have to prevent it doing this. I doubt if you will be able to remove the cog, but you might, but on my 'rude it can be jammed in the rest position with a shaved down matchstick.

Once the spring is wound up attach the new cord while holding the thing in the wound up position. That'll need an extra hand but I suspect this is one of those jobs that is difficult to to unaided but b****y near impossible if SWMBO is helping. When the cord is on allow the spring to gently wind it in. If you have done it correctly there should still be a fair bit of tension in the spring when the cord is fully recoiled but should not quite "come up solid" before the cord is pulled out fully.

Don't forget to remove the match stick. Let us know if that helps.
