mounting a muffler on a soft mounted engine?
Sean , I have an Enya 120R . Pretty old now , I lost 3 mufflers thru the soft mount deal . I have a DR1 & connect exhaust to a remote Muff; by the electric BX type alum; flex . Also the plate holding the muff; on had 2 tiny soc; hd screws , had to retap & put in 4/4o screws . maybe yours is a newer method . I have also modified the outlet from the cyl/head for a better exhaust .
I am the guy who has the AVRO 504K on your site .
