RE: New Evolution 10cc gas engine
Dave,
do you think the factory needle is the way it is for a reason...i'm in the process of of putting my plane together on hanger 9 katana 50..i've run my engine some on the test stand..can't really tell on the stand until the engine is off the load..i did take some 320 sandpaper and knock the edge off the high side needle on the end...i'm gonna run it the way it is for a while to see how it adjusts...what blades have you tested and which size you like the best far as performance ...12 x 6 in the manual says best all around...
