Hi Stephen,
Welcome to the site, there are some really top guys here, they have never let me down. I have a similar problem except I know even less than you. Never had a reel mower before and just picked up a Victa, I had a bit of luck with the motor, Victa 2 stroke Mark II 125, cleaned the fuel tank and carby and started second pull. For me that's where it stops, also mowed the lawn running behind it, I only have a small lawn about 8 x 6 by the time you catch up with it after the first turn its time to turn again. I don't know if the reel part is Victa or something that Victa put their name on.
I will try to find some info on the bottom part and if I have any luck I will post it back here.
Regards Byomarimba

If I can get a large enough hammer it will run for awhile just trying to get away from me
