September 30, 200916 yr Hi guys, I'm from Germany, so please my english is not so perfect. Please excuse me for that. I have a Rev 4T 300 Racing. The engine feels powerful, when I give throttle is all fine. My problem is when I want to stay or to move very slow with the Beta. The engine is running with idling mixture. When I give then 1 time a little bit throttle it goes back to idling mixture, all is fine. When I do this 3 times the engine runs down to idling mixture and then I get a "plopp" and the engine stopped. Is it possible that the idling jet is too small? Or can I change something with the air/petrol screw? Any ideas? Thanks and best regards from Thomas Edited September 30, 200916 yr by ziro
October 3, 200916 yr Author Your air/petro screw may be set to lean. I opend the air/petrol screw now 3 turns. The needle ist now one point higher. The clip is in the fourth position from top. Works very good. Best regards, Thomas
