DSCN1730.jpeg DSCN1727.jpeg and it works excellent :!: no more surching the right amount of opening of the valve. it is easy to adjust with the length of the cable. so, - pressing the shuffle up to the stop makes the engine easy to kick over and still it is some compression to feel. beat :mrgreen: ...

Don't suck any stones in the and put them under the belt. you are right: stones in there will not be a good idea. I am stil surching for a Ideal mesh.... What stops the vent cover closing during a race beat? Can you get to the primary drive without removing the chair? I think your fan may whistle.....

hi SteveS I guess the Wings never have the right bend because the wheel will variate in Revs from 6 00 to 6 000 :grin: the way out for the air is on the holes in the upper cfk plate and three slots in the clutch area. a mesh would be fine, but I guess it will block by the mud :cry: so I get to this ...

hi Andy my B50 leaks as well, sealed bearing in place and lot of others done. the only thing it helps a bit is to keep the oil level as low as I can just see a little drop at the end of the dipstick. I use a heavy 90 gearbox oil, and evan with this low level, the gears seams to be happy for long dis...

Sorted.

so, - all gears are in place

: give the wings a hyper- aerodynamic form....

: fit the wingwheel on to the crankshaft

: and drilling some holes in the primary cover to feed the turbine....

not tested as yet, but I guess, I can't do much wrong by this.
to see, is there a good air circulation now, it needs to run the engine longer and harder for a while.

Cutting C from 33 up to 34.5 will be a delicate work

Rubber should be removed by grinding, - not by cutting.
