[font=''Times New Roman''][/font]Help[X(] I'm about to pull out what little hair I have left[:@] O.k all you gasser god's I need some idea's. I have searched this and other threads and I am not finding an answer to my issue. I have 2 of these engines and recently both have been loading up and dying about 3 minutes after take off. They have worked almost flawlessly from the start 2 months ago and now I am out of my mind with this issue. Both run fine on the ground, idle, transition etc. but right after take off they begin to act like they are starved for fuel and then lose power. Both are mounted in cowls, Pt 17 Stearman and a Ryan STA and even in the hot weather we had last month they ran fine. Here is what I have done so far. NGK plugs, removed carbs and opened and checked for dirt and debris in the screen, checked fuel lines for kinks clogged filter etc. Checked the plugs for gap.025 and they are light tan in color, checked the spark and battery. Props are 17x6 xoar. Nothing seems to matter. Gas is regular,mixed 32:1 using Penzoil aircooled. Like I said they run great on the gound but once in the air [:'(]. I am still new at this gas thing but I am out of ideas and I have a GS funfly I was going to go to on Fri but not if I can't solve this issue. I'm open to your ideas Thank you in advance.
