Re: TN26 resurrection

Reassembly started. I can’t fill the bottom end until the seals get here tomorrow, but I reassembled enough to do a compression check.

Dry (a few shots of fogging oil into those cylinders that sat dry for 50 years) reads 65 psi lower, 68 psi upper. I didn’t look up the optimum but that seems about 25 psi lower than I want to see. I’m thinking the rings are probably sticking a bit.

Starter pulls nicely with the new rope. The float gained .16 grams, or 4% of the total weight, from a single coat of dope. I did apply a second coat which should put the weight right about back to pre-sanding weight and shouldn’t affect the buoyancy too much. If it does, I’ll replace the float.

Fuel tank and shutoff don’t leak, and flow very nicely. I forgot to shut the valve 🙄

Neutral does not seem to disengage the prop, though. It’s more than just free spinning, I think. I’ll block it up and see. I hope the clutch spring didn’t drop below the cam during reassembly.

Everything I see on this engine shows an amazing amount of engineering prowess in the "K.I.S.S." department. This is a lovely little engine! I think I am hooked!

Once I’ve finished this one I know father-in-law will ask if I will refresh his Clinton 5 hp. It runs but that is all that can be said in its favor, more like it declines to die. My husband and I have been married 30 years and Dad’s never done any maintenance on it. Anyone here ever played with one of those?
