Guys,

I've got a P60 with ECU ver 5.0. Had some start problems 3 or 4 months ago where engine wouldn't always start on first start. You recommended replacing thermocouple, which I did. Engine started fine for 3 or 4 weekends, but now is having problems again and wouldn't start at all this weekend after 7 tries.
Either get Low Temp, or Slow Accel non-starts.
New O ring, new thermocouple 1/8 inch into the exhaust nozzle, new can of Powermax, Jet A off the truck at a local airport with 1 quart of BP turbine oil in 5 gal can. After every other non-start, tipped the airplane on it's nose and blew the fuel out to ensure no raw fuel was on the thermocouple end or pooled in the engine. Barry Mattingly is a friend and was there and both he and I have run out of ideas. What's next?
