Performing routine annual maintenance on my Echo hand-held leaf
blower, I discovered that last spring, I mistakenly installed a spark
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 ?
Didn't look glassy at all, just something I've never seen before.
Usually the well-used plugs look tan- or black if it's running rich or
I'd put too much oil in the gas.
