Thx,
Got it on the needles as you described.
I'll see what prop I have tonight. I know it's an APC, either a 16x10 or 16x8. What ever it is, it ran GREAT years ago w/ it on that plane.
I have an OS F plug on it right now.
I'll see if they have coolpower 20% at the LHS and use that at least next time instead of the castor-synthetic blend.
thx again and I'll report after the diaphram comes in and I replace it. I also got a new plunger and plunger spring just to be on the safe side.
