I gave it a bit of cleaning in the parts washer ... then rinsed with brake clean ... then a bit on glass beading in the blast cabinet ... then into the ultrasonic cleaner for a 20 minute bath in half and half ... Pine Sol (citrus) and water.

I spent the day in the shop ... got a lot done ...



Got the skis assembled with new runners etc ...



Guess who forgot to install the wear saddles on the skis before painting ... DOH! Oh well ... they might look cool once they start turning that tarnished copper vert de gris 





Goose rubber ...



And then onto the track installation ...



Drivers and rear sprockets are Kimpex items ... with stainless hardware ...



NOS stock was used for the track adjusters ... all except the bushings which were cleaned and reused ...



That track is in great shape ...



Bogies installed ...





Coming along nicely ...







That will do for today ... whew!

I tore the engine apart today ...



The clutch (incorrect) is worn out ...

The muffler has seen better days ...



I have one coming from Goose ...



It does have the correct fan shroud ...



The flywheel is no good ...



The cam is busted ...



The crank deflection is way out of spec ...



The bearings had spun in the case at one point. Someone applied the plastic insert fix to it. It was well done I think. Also ... the axial play in the rod's big end is out of spec with 22 thousanths of play ...



The cylinder is round but has too much taper. It needs to be bored out to the first over size (75.5mm)



When all is said and done ... this bottom end has just too many problems to fix that I would rather replace it with another. I am looking locally for an 1971 Elan bottom end which is identical to the 1970 292 assembly in all aspects ... and much easier to find

I will also be looking for a first over 1970 T'NT piston. I have a first over piston kit (Elko) but it's for a 1971 292 (ports not the same). Give me a shout if you have one that you would sell or trade( I have a small stash of NOS items, mostly ignition related).

Thank you for that information.  I will do some local research to see if I can Get that around here.
That poor motor has seen better days.... kind of sad but it looks like she had a good life and was well used, or maybe unfortunately abused?

You guys crack me up! I promised myself ... this one I will drive!

A question for you Bones ... I am going to use a 1971 Elan bottom end which is the identical correct bottom for this engine build.

I have a 1970 cylinder and head.

Assuming that I can't find a correct 1970 T'NT piston in a first over ... will an angled skirt 1971/72 T'NT piston work? Or barring that ... an angled skirt OLY 76mm (Type 302)?

I have both the 1971 T'NT first over and the standard 76mm Oly type 302 in the ELKO brand.
