Seanoss Offline OP
2-stroke mower addict!
So while on lockdown the place I had to go get my Pace had a few very dodgy mowers auctioned on ebay I won 3 cheap. This one has had a plate welded to the base with a different engine attached and the lower parts to the mower with some sort of either corrosion or something has stuck to it because it's bubbled up. There is a serial number on the upper case but I'll have to use some abrasive cleaning to bring the bottom of the case back to a normal look but I think it's stuffed but im just interested because of the sides the carby and tha button exhaust are on. Help

You can change the way the carby and muffler are oriented by turning the cylinder 180 degrees..... it may have helped in some way with fitment to the chassis maybe.

Hi Sean’s,

As Joe said but if you rotate the cylinder be sure to rotate the piston as well. Not sure of the orientation of the piston ring pegs to ports but just to be safe.

SENIOR TECHNICIAN & HISTORIAN
G'day Sean ,Joe and Paul

I haven't seen my pace mowers for a couple of years now so can't help with the engine number code ,hope
to get a few out of storage one day.

Yes the Piston needs to be in the correct orientation to the barrel so the ring gaps are not in a port.

Victa / Pace put the carby and exhaust on the wrong side around 1960 ,other than the Pace a quick
mention of other Victa backward motors would be the Sheerline , Viceroy and Cadet.

It's like Victa looked at Pope mowers and said lets copy Pope mowers (early Pope mowers are wrong) but Pope in the early
sixties changed to having the carby on the same side as the earlier Victa mowers and Victa
decided to follow suit.

The major thrust side of the piston should not be on the exhaust port side ,I did a quick test of temps
today ,I quickly started a 2 stroke and measured 16 degrees on intake port side and 68 degrees on exhaust
port side (motor not warmed up) so clearly it can't be good for piston skirt wear on the hotter side of the
barrel.

In a car engine the surface temperatures of "Cylinder Head" and "Piston" can reach 260 degrees Celsius ,I would
say the warmed up 2 stroke mower would get hotter than 260 on the exhaust side and some 2 stroke exhausts can get to
620 degrees ,obviously not a great idea to run the major thrust side of the piston on the hot side of the barrel.

Cheers
Max.
