As if I haven't enough on my plate I am going to restore this little baby as she has a bit of history to a forum members family.




I started off doing a compression test and one cylinder was very low not a good start As it had been sitting in a barn for the last 30 years I decided to put a bit of WD40 in and let it sit over night hoping it was just stuck rings. I did the test again and was getting 125 psi on each

Bottom



Top



I had a look at the gear oil and of course it was half full of water:grrr: it had been sitting for so long it looked like you could drink the water if you held your nose



Next I took off the air breather to have a look at the carb It looks like some sort of spider lived in here, what a mess.



Even the carb was full of spider **** or what looks like sawdust.



Can things get worse, O yes they can. I checked for a spark and guess what...........none so out with the harmonic balancer and off with the flywheel.



I think I found the problem.






Parts ordered carb rebuild kit,coils,condensers and points I also want to change it to a standard fuel tank from a pressurised one so I ordered a mikuni pulse pump the plan is to get the engine to run before I decide to carry on with the rest of the rebuild.

This young forum member does not realise how lucky he is to have this genius on his side Fergal your a star i just knew you fancied this project!!
"Petrol and diesel heads having fun"

Well done lads!!!

A don't say that now they will expect me to get it running

You can still get most of the parts for this engine as it was unchanged for 20 years Marineparts do some and the rest I got on line, the cowling parts and decals I'm getting from [www.nymarine.ca] not cheep but good copies.

Jeepers Fergal, is there any project you won't take on.....?
Fair play to ye, and you make such a great job of them. I remember the first time I seen Sean-Nos as we pulled up alongside you at a roundabout near Galway on the way to the Corrib. Noone in the car would believe me that you had built it yourself......!
Keep the pics coming, it's always a pleasure to watch a craftsman at work.....

thanks for that, I'm working on a early 1970's evinrude 25 sportster, found i hard to get parts, got head gasket from evinrude, still have ignition issue,have spark, have fuel but wont run !!

1 Did you do a compression test on it,

2 Is the spark good and strong.

3 Are the plugs wet if you take them out after trying to start it.

Put a drop of fuel into each cylinder and try and start it if it kicks a few times then try a few drops into the carb it should run for a little bit if so your problem is more than likely your fuel pump or a blocked jet in the carb. If your having a hard time getting parts let me know and I will try and find them for you.
Best of luck.

Enough of this engine you can have it back now If there is one thing I hate about old engines it's sized and corroded nuts and bolts it took a few hours just to get the intake manifold off, there is something about steel bolts and aluminium they do not like each other for very long let alone 50 years Still a bit more stripping to do so I will let them soak in WD40 over the weekend then the next job is to get all the paint off and fix any dings before the etch primer.

Hi
I replaced the carb with a made up one from an ev. 75 (!) and she now runs however every now and then she coughs and on several ocasions stopped dead !
Compression is great, spark reasonable .

I wonder is she getting too much fuel from the bigger carb and flooding the engine, next time it happens have a look at the plugs to see if there is a lot of unburnt fuel.

Fergal

My respects, despite today's politics you continue to potter away with your project.

M(W&W)F

Yep, respect Fergal! The pub is on fire, but you continue to pull pints

You are an inspiration to us all

Cheers guys, Well I think I found why this engine was put away the two condenser wires were rubbing off the flywheel making them arc out, with the new ones I will hold the wires down with cable ties to be sure to be sure.



After finding this I rebuilt the carb and put in the new electrics and then this happened " click the pic"



Now to strip it back down and get sanding.

Brilliant work Fergal
Keep up the good work and please keep posting updates on any projects you are working on.

Cheers
John

Out with the old and in with the new, the new condensers are much lower than the old ones so they must have copped on to that problem .


Here you can see the old float next to the new one it mush have been dying of thirst the new needle valve now comes with a little clip on spring to stop it from sticking as the last one just relayed on gravity.



Rebuild kit fitted and a bit of a clean should be as good as new or even better.

Super job Fergal. Respect! Thanks for posting the pics.

All the parts back after been vapor blasted by [www.tadltd.ie] they also do antifoul removal and have a mobile unit. With vapor blasting you can remove paint by the layer it's so fine and it will not harm the aluminium you can even polish with it, I have it dull with an etched finish to give the zinc chromate primer a good hold.

Hi Fergal,
At the rate your going you will have it looking "better than new....".

That vapour blasting looks like some job. Is it expensive, what would be the going rate for a quantity of components like you have shown ?
(I know a certain Motorcycle fan who may have a use for such a service.....)
