I have 3 DA60 and 1 DA70 and very pleased with them, using DA engines over 15 years . One of my DA60 on my pilot RC extra330SC 92'' +MTW RE2 pipe has a problem. Each time at the first start procedure 15-20 times hit but no result then a few times backward hit then engine starts normally, and insane power 24X8 CF prop 7.100 rpm 900 meter ASL. Afterwards all day each start is very easy and 1-2 flip . Nex week when I go to field again 15-20 normal flip then 2-3 backward flip after then hit backward starts normally
Anyone has idea?? what is the problem?

check to see if your carb diaphram is getting stiff. If sounds like you have a fuel delivery problem. Also, your low speed needle could be just a little lean. I always put a finger over the carb and pull the prop through (ignition off) until my finger is wet from gas.

Thks for the comment, will open the lsh 1/8 and try. But there is no chance to put a finger over the carb till gas comes ,feel gas because all covered with huge cowling.Hope opening LSH will solve the problem thks anyway

+1 on the lean low needle try opening it a tad , the width of the needle slot to start with . Running backward is a sure sign of a lean start .

Thks for all comments , I will open the LSN a little and try but just to remind you all , engine starts after hitting15-20 CCW then one more hit CW ,it starts but not spinning clockwise, normal turns.
Anyway seems that will be ok by opening the LSN a bit.

Yes 1/8 opening LSN solved the problem. Now DA60 starts much more easily , no need to hit backwards for the start. Thks for all reccommendations
