Subject: Re: RotaxEngines-List: 912UL rough at around 4000 Oddly the same thing has happened recently to people on the kitfox list. I do not have a 912 but I am led to understand that lowering the clip on the jet needle by one notch ( raising the needle a little) will make the mid range slightly richer and cure this problem. Again, I have never touched a 912 and am simply passing on what I read. Hope it helps. ________________________________ Message 2 _____________________________________ Time: 08:21:37 AM PST US Subject: RotaxEngines-List: Re: 912UL rough at around 4000 From: "lostpilot28" Hey guys, Thanks...this sounds like what I need to do. How exactly do you adjust the Needle Jets, though? I'm no carb guru, but I thought the only way to adjust them was to replace them with shorter/longer jets. If you CAN adjust them (by a turn of a screwdriver, per se), how do you know what the new setting is or will do? Much thanks! Sonny W.
