Hi all,

About lugging this engine down : OS recommends a 15/8 prop in the manual, which was surprisingly much prop to me ( I had bought a 14/8 together with the engine, before reading the instructions). Everybody on this thread seems to use a lot less prop, and still the engine overheats ... ?

Because everybody blames the remote needle valve, I have bought a GMS 2000 remote needle valve assembly, and I am planning to use the 14/8 once the engine goes into my 70" Extra. I will also use a soft mount, although most people say that the bubbles are not caused by the vibration. Everybody uses low nitro content in my club ( about 0-5%), so I will stick with my normal 5% mix. OS#8 of course.

Break-in seems to be critical, so I will be careful and patient there.

Maybe I will be one of the lucky ones, where it all goes well

Cheers,

Kris
