Dear Pud. Exhaust is built inside the welded parts and partitions these parts .. just probably shaking apart over time and partly blocked the gas port .. would recommend that all 200 hours might have to dismantle the exhaust and hear if there are no parts released inside. Regards. Ferera Moshe.

Dear friends .. I found the problem ..! After investigations of carburator not found anything I concluded that maybe exhaust is the problem .. dismantled the exhaust and I found parts, Parts I found reduced the amount of gases emitted from the engine strangled and drop the rpm. I thank you all for the good will .. maybe it will help future similar problems best regards. Ferera Moshe.

I have a problem with the engine ROTAX 912 when I start running to takeoff I have drop the fall of 300 rpm. Can someone give me an idea how to solve the problem?
