Burping

I have no dog in the fight either way, however I am much more inclined to take a Rotax trained person's word rather than yours's

I also agree that a short time between hot and cold burping probably makes it a non-issue, however, I believe its a good practice not to get in the habit of burping hot since you may not know how long it will sit before the next flight.

Hi James,

Your mechanics advise has no negative safety or mechanical issues - he is talking mythology but that okay, many live very happy lives believing in such.

No offence taken or given. 😈
