Hello,

Been having a very bad time with one DA150. This is a relatively unused engine and I am unable to get it to run right. It was broken in with lawnboy ashless in 2011 and since then never used. I recently installed it in an airplane and running with a menz 32x10 and pennzoil 40:1 regular gasoline. The engine starts in 2 flicks.. no issues..

I am getting no more than 5090 rpm on the ground. The H needle is about 1.5 and the L is a shade less than 5/8. ON the ground the transition is not very good and in the air the engine sounds like it will quit any time. Any advice? Should I lean out both needles?

One thing to note: With a XOAR 32x10, I get almost 5800 rpm on the ground, but then it sounds awful in the air…so I changed the prop to a heavier menz…. could this be an indication to something?

I am all set to send this in to the factory if it doesnt work here.

Thank you
