Speedy I know how you feel, I am having the exact problem with a genuine honda - sometimes it goes first pull, sometimes no spark, sometimes faint, sometimes perfect, sometimes backfires
I read this morning that honda allow gap between .008 inch to .024. Can't get the damn flywheel off either to get a good look at the key.
They are a good engine though and on a Victa base would be much nicer to use
