2hp Evinrude
I set the engine on a piece of timber held in the bench vice then took out the spark plug and checked for a spark no such luck so I decided to remove the flywheel and check the points etc. The first task was to remove the top shroud which is secured by four bolts.
The view above shows the bolts securing the top shroud they are the ones that have been slackened back not easy to see. Once the shroud was removed the flywheel is exposed , it is retained by a central nut and washer.
Flywheel securing nut
The flywheel is fitted on a taper with a woodruf key and requires a puller to remove it, I made a simple puller from a piece of scrap plate, its not pretty but it does the job, I drilled three holes in the plate to match the three tapped holes in the flywheel. After removing the securing nut I fitted the puller with three 1/4" UNC machine screws in the tapped holes and tightened them up, there was a bit of a crack and the flywheel came free.

After removing the flywheel I checked the ignition system, just a coil,contact breaker points and a condenser which all looked in good order.

I cleaned the points with some fine wet and dry, it should be a proper points file but I did not have one. I had already removed the petrol tank so gave it a clean out with some fresh petrol before replacing it and the flywheel.
Tank and flywheel replaced
The tank is secured by a couple of spring clips which fit through a couple of moulded lugs on the base of the tank one of them is missing on this engine.

I removed the float bowl from the carburettor with the intention of cleaning it out but it was remarkably clean so I checked the jets and replaces it. It was then just a matter of replacing the shroud and filling the tank with some fresh petroil mixture and pulled the cord, after several attempts it started and after some adjustment of the jets it ran quite well. I need to rig up a water supply so that I can give it a proper test run but it looks promising, now all we have to do is get past this virus nonsense and I can try it on the water.
Good morning
ReplyDeleteHow are things going on the boat projects?it’s been quite a while since I checked in on your site. How is the heart doing? I hope you have gotten that fixed. I have had more heart procedures since last we communicated and I hope my issues have been fixed.
My M33 is still a work in progress (aren’t they all). My main project at the moment is replacing the plexiglas in the starboard fixed port light. I’ll have to look back at the post you wrote on replacing the fixed windows on New Horizon.
Merry Christmas to you,
Peter
Hi Peter
ReplyDeleteIt has been a while since I posted anything on this blog in fact I haven't looked at it since the last post. The heart is doing OK I managed some sailing this year when we weren't 'confined to barracks' went up to Bradwell on the east coast and then a few nights up in the rivers Roach and Crouch otherwise mostly local day sailing. New Morning is also still a work in progress and this year there has not been much progress but recently I have been motivated to finishing the door frames in the heads, see the next blog post.
I hope that the heart procedures are successful and that you had a peaceful Christmas.
Have a happy and peaceful new year
Peter
