I started wishing for a Lycoming if 100 plus blades before burp were required
100 blades is normal after sitting a couple weeks especially on a model 4 with the higher mounted tank. Seen this on brand new Rotax engines and is no indication of engine health either way as jrthomas stated after talking with Roger Lee, so not sure what is implyed by the statement in quotes above. Roger is not the only highly experienced Rotax mechanic to confim this normal Rotax specific characteristic.

I've also found the most accurate oil level readings come from post flight checks and if you are flying as often as someone like slyfox then his described pre-start procedure works well and I have employed it many times. I find with my building taking precedent over my flying lately that long periods of inactivity require burping pre-engine start just for piece of mind.
