Question for you all...

I have a hangar 9 sundowner(second one by the way) with a Evolution 35 and I'm having a hard time with dead sticks...


The first flight on my first sundowner ended in a deadstick that I believe was caused by a lose spark plug wire. I didn't seat the clip correctly. I'm beginning to question that reasoning as I had another deadstick today and at this point I'm losing alot of trust in this engine...

Reading sundowner fourms people are recommnding closing off the half of inlet hole in the cowl and adding big holes in the bottom to maintain airflow. They are recommending this as they believe that there is an airflow distrubance caused by the choke lever. Well I did all that and I'm still having this engine quit on me. This is my first gaser and I'm assuming the mixture is good. Good transitions and it four strokes at idle and no where else in the throttle range. Other Evo 35 owners at the field says that it sounds fine. Mixture is 32:1

So my question is, will a velocity stack help? If so, where do I get one. The wider one shown in the picture above looks interesting. This looks like one, but I'm concerned this will not allow me to reach in and choke the carb by using the actual plate versus the lever. http://www.horizonhobby.com/Products...ID=EVO30941321 Because of the fit in the cowl, I don't have access to the lever.

Any suggestings?
