Tuesday evening I took my reworked Nobler - reworked after a horrific crash - beautiful rebuild by my brother - to the field for the first time. Balance and flying qualities were better than ever. It has a Brodak 40 in it which has been a wonderful engine for me.
However, on the third start up - the Needle Valve would no longer adjust the engine speed. Later, it started to move around without being touched. It seems to be tight now that it's on the table. Any ideas?
