I solved similar issue using tester SKU RC1220, checking valves and plugs gap carefully. Now it runs great. Note i damaged the bearings, conrod and main, due to runing the engine with spark too much advanced. I replaced the bearings. Good flights.

Any good quality 2-stroke synthetic oil designed for small high performance engines (strimmers, blowers etc). I also have used Klotz or Coolpower oil for model engines. No need to use 4-stroke oil unless it is designed to be mixed in the fuel.

I have since found out that using motorcycle oil such as Castrol Power 1 TTS Racing can gum up the valves. So stick to aero model oils.
