Mr Cox,

you read it selectively. I said two things:

1) I can run it indoor only at idle else the neighbours will complain

2) When I run it rich at full throttle it gets hot

Anyway, I will try other prop and fuel combinations. Interestingly, as I remember from a couple of years back, we used everything from 14x4, 14x6, 14x8, 15x4 on this same engine and it never seemed to overheat or develop squishy compression then. The more I think about it the more I feel it is either a blockage in the carb or a fuel problem. Remember it continues to run even at 4-4.5 turns out of the HSN needle?

I am getting new alcohol to make the 0% nitro fuel tomorrow and I have already flushed out the carb like I wrote earlier. I will keep my fingers crossed for Sat / Sun.

By the way, I have just decided to but a DLE20 for another model. There will be no further new nitro engines for me after the 2x55ax, 1x75ax, 1x72a, 2xFS91SII, 1x120ax I already have (1x72a, 1xFS91SII, 1X120ax are still in box, both the 55ax have been shelved for the time being. Yes, there is one engine reserved for each airplane I have, but most are still in boxes)
