That is a pretty incredible motor and exhaust you have there, my friend.  Amazing.

Thanks brother, and thanks for turning me onto the Marbles paint.

Just some O-rings, canít those be replaced by some generic ones of the same approximate size? Or are they some special material?

Probably me being too particular, as usual.   ::)

Honda O-rings are probably Buna-N.  ;)

I prefer to stay away from Buna-N, only good up to 200-250 degrees. 

I ordered a couple packs/sizes Viton Flouroelastomer super resilient, 400 degrees, from McMaster-Carr  (thanks IRK  :D )

they are a "close" fit for the Bastard sized, 16.5x2mm Honda discontinued Oil Pickup O-ring.  Of course.

I will just have to fit the best one, (and pray it dont suck air).

They run $5-$10 a pack.  And that will add up fast to replace them all.

Anyways, while I patiently wait for Honda dealer parts dept to pull off another miracle.

I got plenty to do. 

Ready for some new seals, O-rings, gaskets, clean up threads, re-torque head, adjust valves, static timing

And I got all three engine bolt kits to install.

Things may slow up a tad, as Rachel and I just discovered "Americas Got Talent" on Hulu.   ;D

Read a couple horror stories about 400-fours old starter O-rings breaking and dumping oil everywhere...

Fresh.



And this is going to speed up the plan of re-building the spare engine.

This morning I pulled the kickstarter out for inspection and found the support cracked.    :P

I then checked the spare engine and found its good.  :)

Rather than mess around swapping cases I will start the rebuild on the spare asap this spring.

Then, If I cant find a suitable replacement, send this one to Hurco for repairs next winter. 

Ill bump start the thing before I kick it anyways.  As my old knees cant take kickstarting anything more than Piglet anyways.   :(

OK the thought of HALF ASSING a project (even temporarily) drove me nuts all day...

So now this matched pair is on its way. 

"Do it KINDA right or Dont do it at all".  Only if I have too.   ;)

Ill pull the engine back out of the frame tomorrow and prep for the swap.
