Its winter now in New Zealand with daytime temps in the 10- 15 degree C range. I have an O-200 that in the circuit at about 800 - 1000' after takeoff runs rough for 1 or 2 seconds then runs fine. Often it only does it for the second or third circuit then not again for the rest of the session, or even the rest of the day. sometimes it only does it for one flight in the week, other times 5 or 6 times per flight. Never does it if I takeoff and cruise for an hour. Had the same problem a few years ago and figured out that the W100+ oil I had just changed to was the problem, the engine then had 100 hours since overhaul. I read a thread on another forum that recommended not using W100+ oil on O-200 engines with ECI cylinders. Thats what I had. The thought was sticking valves. I changed back to W 80 and didn't have the problem again. Now we can't get W80 so I have used W100 for about 3 years with no problem. The engine is now 1250 hours since overhaul 8 years ago.
What things should I be checking to find the problem?
Any suggestions gratefully received,
cheers Bill
