Haven't spent a penny on it yet. Still in assessment mode. If I can get it together cheap enough I will while looking out for a 70 -100 hp. If she becomes a runner I can sell later and recoup parts cost hopefully. Now it's just a bunch of parts. Pain selling one bit by bit on Ebay to fund another. I have been listing extras recently to fund any purchases, already sunk money is easier to spend mentally than new money.

Hey Larry, I thought you were going to hold off until you found a bigger motor?

Been puttering away. I have pretty much got the foot apart, minus pulling the top race out. I have most of the list of needs for it, its pretty long......

On the motor end I got the carbs off, apart and cleaned out. Luckily there was only the sand on the front side and a few grains that went through the holes in the butterfly on the back side. I took them fully apart and cleaned them super well inspecting everything. There was no sand in the motor (except a few grains I knocked in taking the carbs off). I scoped it and the intake track looks good and clean. I am not too comfortable in taking it apart much further. I could probably pull the head but that is a big job with lost of stuff needing to be removed. I will pull the plugs, ground the wires and turn it over by hand to see if I feel anything just to be on the safe side.

The carbs have one issue. What is called the idle tube, on both carbs, are cracked. These are very small tubes a 1/16" bit will not fit in them. They screw in from the top and go down all the way to the bottom where they must sit in a pool of fuel. They have two holes at the top to distribute fuel. With these cracks it must not have had a stable idle from excess unmetered fuel which would explain why the idle screws were adjusted pretty far out of norm. These parts do not have a separate number and were part of a full kit that is of course NLA. Im thinking unless somebody has a pair of junk carbs with good tubes (if mine are cracked are any good?) I'm going to try and solder them. They are brass so it should work just a light swipe of flux and good silver solder should sweat it without
filling the tube in and clogging it shut. Any thoughts on this?

That one does look nice. I'm trying to be good and not spend too much right now. Hopefully by fall work will pick back up and I'll feel comfortable dropping some coin.

Ray, I saw that Post and almost dialed his number. But... I have enough going on right now. That motor looks like one heck of deal.
