Not, that is, unless I spray a

into the carb works just as well. It's a bit of a fiddle taking the
air filter off then screwing it back on before pulling the cord -- but I
know it works, so that's what I do.

But: why bother with taking the air filter off?

"Sure Start" in the air filter works, too. I sort of point it in an
accessible air hole in the air filter cover, give it a spray which presumably ends up
that foam thing, and done.

Ooh thanks Thomas - I'll try that! :-)
