They have no decompression valve like a Victa ( mine doesn't seem to) so it is tougher to pull. A bit crude IMO. Mine won't so much as as utter a pop and it has spark. Maybe spark died under compression. In any case, I am happy to swap it for an amusing old B&S.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
