I don't want to do it........I'm no good at engineering........I can't do this.......... its going to end in disaster........................NOOOOOOOOO!
I mean what is this bit - its attached to the manifold top?
And the manifold won't come out without this bit attached!
Seriously who does this design wise?
That just looks way too complicated - all those wires - something to do with the carburettor and choke.
I'll never get this back in - it will never work again!
I mean seriously, no seriously, how do you disassemble this?
OK time to take thousands of pictures to piece it back together again in a fortnight's time
Please God, don't let me have to re-tension these
So, to lift out the manifold, I have to un-attach this...........ugh!
Right, don't drop anything down that hole - cover it over now
OK - now to take out that bolt!
Please don't let anything drop off or spring out of it.
OK, so under wraps - one carburettor; one petrol tank and support base; assorted bolts, washers and collars
The cable pulley mechanism is back reattached and bound in paper towel and masking tape so nothing works loose.
I have no idea how to store a carburettor for two weeks other than allow no dust in it?
Frankly, I think we can all agree, it will be a miracle if this engine, once reassembled, ever starts again. I wonder how much a new carb is.....?
In the meantime, thank you Paul for being a knight in shining armour and riding to my rescue!
Well done.. fascinating stuff... those cables look like standard bike brake cables... You begin to understand that hundred quid odd is not a lot really for an outboard service... I price my own time at 20 quid an hour... ! :o)
ReplyDeleteThere was a chap talking about reconditioned carb's (good as new) on the YBW forum the other day, Honda rather than Tohatsu, but the gist was forty odd pounds complete... but you won't need it, it will run sweet as a nut..
Bloody hell - talk about a man of faith; in your own abilities, and all power to you I say - Me? I would have crumbled at the first sight and taken the motor to an outboard mechanic with 1000 years experience (In NZ with a complete shutdown of everything that would mean a long wait but needs must in these difficult times).
ReplyDeleteYour description of undoing things and bits popping out and flying everywhere bought back some very bad memories (a spring that I never found and a nut left over after everything had been put back together ahhhhhhhh).
I hope it all goes well and may the force be with you.

ReplyDeleteLooking at a parts diagram for that engine, the cable mechanism you are seeing is the throttle linkage. It looks like a pull-pull mechanism transitioning from the twist throttle to the carb. One of the cables will tighten when you advance the throttle, the other will tighten when you retard the throttle. The rigid linkage should actually connect to the throttle butterfly.
As far as tensioning when you re-install things, don't worry too much.If there is too much slop in the throttle, tighten one of the cables a little. If things are binding, loosen them a bit.
Best of luck!
God bless!

Steve, Alden, your faith in my abilities is wonderful - thank you! Wish I had the same faith. Steve, you are right - £120 for an annual service doesn't seem much and in future I will probably get it done professionally. On the other hand, I have been fleeced by the people who sold it to me originally and then by the same company who have serviced it the last four or five years as none of them told me about the gear lube hole issue and the quality control mistake. So, I need to find a more honest service team - Tohatsu UK may have inadvertently put me in touch with a local one I didn't know existed. I will meet up with them in a few weeks when lock down is lifted and sound the out. Alden - thanks for your encouragement.
ReplyDeleteWayne, you are a spooky man - I was just looking at the parts diagram earlier and working out what the wires did. It looks similar to something on a
Vespa I once restored and so I'm sort of familiar with the principles. I am hoping that I got this right when I wrapped it up and secured it in paper towel and masking tape (so that nothing would pop off).
I'll let you all know how it goes in a couple of weeks time - thanks for all the encouragement and advice guys - most deeply appreciated - thank you
Steve:
ReplyDeleteThe Vespa linkage is probably very similar indeed. The reason for using two cables is that a cable is much more positive when being pulled than when being pushed. In this case, one of the cables is always pulling.
I am sure you will do fine putting it together. Take your time and don't panic. You are almost there.
God bless!

Thanks Wayne - as long as I dont get them the wrong way around...hahaha. you take care now - stay safe and well
ReplyDeleteIf you get them reversed, the throttle just operate backwards (faster and slower will be reversed). You would spot that very quickly in bucket testing.
ReplyDeleteYou will be fine, Steve. If you reverse the cables, the throttle action will be reversed (slow will be fast and vise-versa). When you test it in a bucket, this will be very clearly obvious. At that point, you will think some choice words, fix it and all will be well. Otherwise, all will be well the first time.
ReplyDeleteBest regards!

You are a good man Wayne, thanks for the positivity and encouragement. You take care now.
