Had some luck yesterday, a neighbor gave me this old Masport..... He just put a new spark plug in, didn't help. It would have been better if they gave him the right plug. The arm electrode was bent to the centre electrode and the ceramic was smashed........
Anyway I emptied the oil and held it verticle plug hole down and flushed it out with petrol to try to wash any smashed ceramic out.....
It had good spark, but I decided to take off cover, lucky I did as heaps of gunk around coil, and I put wire wheel on flywheel and checked gap...
Flushed fuel tank. Put old oil back in to right level... Put sharpened old blades on....
Started it with Bosch electric drill....without throttle cable just to see if it ran.....
It ran sweet, so I mowed the back yard. Just go it to put it together....

Oooooo! A vertical pull spinning top model.
I recently read that surface rust on the coil and flywheel doesn't affect starting performance.
Best make sure no fragments got in there as it will mean sure cylinder scoring.

Glad you got the chugger running.


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

The old put the OHV plug RJ12 in place of the LM19 plug will do it everytime.

And Mowerfreak yes the rust doesn't affect magnetism but if someone tries clean off the rust on the flywheel magnet with a powered wire brush it can de-magnetize the magnets. The rust on the coil to worry about is where it makes contact with the crankcase (ie the grounding of coil).

The only time I clean off the rust is it is impeding the rotation then it is sandpaper only.

Wish I knew about contacting the crankcase when I refitted the coil to my two stroke Victa recently AVB. It's a bit temperamental to start but that might be the carby needing a clean.

speedy, a quick brush of Aldi black metal care paint on the top surfaces of that motor lifts up it's appearance.
I did mine months ago and it still looks better than when it was coated with surface rust like that.

Noted AVB about the wire wheel....
And good idea MF, got it sorted.
I put my Wifi bore cam in for a look, couldn't see and porcelaine pieces, but you can see the dent in the piston from the sparkplug.... I put up a few pics just for show and tell.
I took off the cable which was broken at the throttle handle end. I took out the inner and straightened it, taught by old school gent. cut outer to match .....
Set it up , got ignition cutoff working.. did a short mow, forgot to put oil in, put oil in and oil treatment... mowed front lawn.... nice little mower.....
I'd have it as my main mower...............but it's got to go.....
Lucky I'm in Bundy with warm weather and a bit of rain....... equals lawn growth......
equals.. mowers wanted...
I mowed today, every week
cheers
