YS 140 Sport stock muffler

Hi Guys , need some help again . On flying my showtime 90 the muffler fell off ,must be vibration or something ????? As a result I have to replace it . The engine is a YS140 sport and the manual does not have a part number for the muffler (standard muffler) I chequed central hobbies online and thay have no muffler on the 140 sport parts list , the ys fz 110-s has the same muffler style as the muffler I had . I am wondering two things, can the ys fz110-s muffler work (is it the same size and threading?) and if I run the engine with out a muffler do I have anything to worry about other than the noise? You help will be a big help to me . Thanks guys

Adam,

YS has a support forum under "Glow Engines" (I think) here on RCU. You may want to ask a moderator to move this post to that forum. I have a YS140 Sport too, but I bought mine with a Slimline smoke muffler on it so I can't answer your question.
