Okay, carb is now drawing fuel. av8tor's suggestion with the WD40 did the trick. However, now I find a problem with the high speed needle. Both H and L needles set to 2 turns out to get engine running. Engine starts and runs very steady at around 4500 rpm. But when I go to WOT, the high speed needle does not make much difference in rpm performance. I can turn the needle wide open or almost fully closed and it doesn't change the rpm. Also played with the L needle in and out and cannot find a combination of the needles that perform well. The max rpm I can get out of the engine is about 5000 rpm and it will idle down to about 1400 rpm and stay running.

I got the DLE30 carb and put it on. With it, I can get about 6700 rpm peak and a steady idle of 1500 rpm. For now I will stay with the DLE30 carb. The Walbro WA197A is going into a drawer. I still think the top end rpm is a bit low for this size engine. I may put on a smaller prop such as a 16x6 or 16x8 to see what I get for rpm. Maybe the Xoar 17x6 is just too much prop for it.
