Hello Everyone.....

Just to tell you that following the recomendation, I solder a tube into the pressure hole and run a tygon line from there into the fuse tank compartment.

All my problems were solved.....the engine gets easily tuned with just 2 turns of High and low needle,,,,,and never varies in the air giving me a great flying sunday with 7,800 Rpm on a 18x6 wood prop and very happy to finally being able to get my conversion engine completely ready, (and without noise given the tuned pipe and long header)

I´ll post some pics as soon as I get my camera.

Really thank you very much to all (happy to say that I convert this engine from scracth following all the recomendations given in this forum)

Best Regards
VÃ*ctor.
