My mates Victa Super Catcher with BS 550ex started and revved OK........ but he had problem .
Anyway I cleaned airfilter as it was full of gunk, blew air around engine to get rid of dust. Sharpned blades and cleaned buildup of grass/dirt underneath.
I mowed the backyard to test it and it was OK......
I just said use 91 unleaded, not 95 or 98..
So he's happy and a six pack is on the way.

I'd like to get a spare carb from tipshop to check the other engine........
speedy

........................Keep your blades sharp......................
