G'day Daryl,
I've had 2 stroke mowers run like that when the spark plug is no good ,even if it's new, I always test a mower with a spark plug that runs well in another mower
They run like that if there's a spark problem ,fuel problem ,air leak (port covers, crank seals,gasket problem)
The points and a condenser can be used from a later 160 cc Victa 2 stroke ,they all interchange.
I converted a seventies Victa 2 stroke from points to electronic ignition and used a coil off a side pull 2 stroke but the coil
had to be put on the core backwards ,I put images on this site but can't find that post.
Sometimes you need to remove the muffler and make sure the port isn't restricted with carbon and the muffler isn't blocked.
Cheers
Max.
