91 FX muffler
I hear that an E-4010 muffler, even though it fits the engine, will overheat my 91 FX. I was given a used E-4020 muffler but when I took it apart I found the 4010 and 4020 seemed to be identical.
Is there a big difference in the baffle, etc between these two? I haven't used a mic yet but they certainly seem to be identical.
(Of course it may be that the used 4020 is a composite of parts and not really an E-4020.)
Regards
