Performing routine annual maintenance on my Echo hand-held leaf

plug one heat range hotter than specified. The blower was used plenty
with this wrong plug in it- and the part of the plug inside the engine
had a heavy very light gray deposit on it.

Wonder if that did any permanent engine damage or shortened its life€¦

Â* You haven't hurt it . If you had , you'd know because it would likely
have locked up . Do get the right plug , that light gray deposit , was
it like glass ? Or more like oil deposits that had burned very hot ?
