I just looked at N11781, it has been sitting for 8 years with the engine ground run periodically, owner is ready/forced to sell but wants to put no money towards an annual or other repairs.

Good; very clean and straight airframe, 1878 TTAF, interior and paint, exterior plastic all original, 7 or 8.Very little surface corrosion inside wings or fuselage. Static RPM 2350

So so; no rudder stop AD, no ADSB , Icom A200, Cessna 328 , AT 150 and encoder. McCauley wheels and brakes. Slick 4301 mags. field? O/H at 1300 hours

Not so good. rusty cylinder walls, left mag intermittant 250 RPM drop, troubling vibration from 2000 to max, possible case 1/2 oil leak, damp on top and wet on bottom of engine, carb and oil tank.

He is asking $15K , I would not fly it until vibration issue is resolved.
PM me if you want more particulars or the sellers phone #

Sounds like a possible bargain for somebody, Alan.

I'm going up next week to look at the mag drop and vibration, he figured the plane needs to be ferryable at least. Alan

Fouled plug was cleaned so mag drop is good now. The lifter is collapsed on #4 intake so the vibration increases with RPM after 2000 as that cylinder peaks in power production. Amazingly the prop balance shows very good, guess the transducer orientation and the cylinder are 90 degrees to each other and transducer can't see the other vibration. Alan
