Hi Hobbsy,
I just picked up a Webra 91 Speed RC engine...tis a beautiful piece of machinery! In reading through your posts you seem to be very knowledgeable on the subject of mufflers for these engines. (please take that as a sincere compliment - BTW)
I need to figure out a muffler arrangement for my engine as well. I'd like to be able to install a muffler like the Powerbox used on the OS 120AX or the 95 AX that allows multiple positioning. Would these mufflers work for the Webra 91. Obviously I need to drill and tap holes as well, which I do not have a drill press to do with.
I welcome your thoughts.
Tom
