Hi CEN,

First of all: nice to have a reply from an official CEN representative - appriciated.

Fuel tubing is new - why should i replace this ?
I am running an in-line fuel filter - a 2 mm Graupner i think it is.

I use a fresh air-filter with normal air-filter oil.

I will try 1,5 turn out from flush on the low end needle...have had best idle with about 1 - but will try of course

Heatsink, backplate etc. all nice and tight. Carb has a thin layer of silicone gasket, as well as the O-ring - so should be tight here too...

I am running a home-brew: 25 percent nitro ( fresh from local hobby shop ), 13 percent synthetic and 2 percent castor ( organic ) oil and then of course 60 percent methanol - also fresh from hobby-shop.

I am planning to fit a check valve ( one way valve ) into the exhaust to fuel tank line, as suggested by several in this forum. I never ran a half tank of fuel since i broke it in ( mostly idle ), cause the damn thing is running hot on me - so i dont know whether my Genesis will experience the troubles described, at half tank. But its worth a try - engine must be running lean somehow / under surtent conditions.

BTW - are you the same CEN as when i order parts from [email protected] ?. If so - i must say i am impressed with your service and how fast i actually get the parts from you ! Thanks a million - if you are the same guys of course

Tks again and best regards from Denmark
Niels
Geez! Ya dont think that fuel has anything to do with it[X(]? I guess not cause if you thought it,you would have said so.I might try some decent fuel before I go off the deep end
