Having problems starting with MDS 38 in Ergo. New motor Settings at 2 1/2 on both needles. Using Cool power 30% Heli fuel , Hanger 9 #3 plug (McCoy). First tank ran thru fine at rich idle now hard to start. Is this motor normally tempermental? Should I change to another brand? OS? What will go in the Ergo in it's place? Will it require adaptation? Thanks
