Hey Unkie,
You cannot buy the snorkel for the Rotos unfortunately. They come up on ebay occasionally or you can use the A/M new for the specials. Dont worry Im short a few as well. I saw a few listed a while back,straight roto ones that were new,I msg him and got no reply,so I scoured the sites and couldnt find anything,so maybee his were old stock? Others may know of other sources.
The tin wheels came with a brass sleeve.and yes they are usually worn down as is the axle. You can do it one of 3 ways. Ream or die grind out the old sleeves ( there are 2 in each wheel) You can replace with brass,which usually have a thin wall or copper slightly thicker wall and often a nicer fit. The 3rd while some may think a bit bodgy is STD garden hose. This has 2 advantages.its a perfect ext dia' fit and you can drill the centre to size,which is almost accurate any way. It gives a tighter fit on the axle and is quieter and also does not cause any wear to the axle.
The Cable should be straight for your Roto 2 It was in the 60 thousands right? The bent cable sleeve came later in the roto run.
And YES 100%....The WHOLE mower chassis was painted GREEN,Including the axles and Flywheel Cover and Tin Wheels.
A million more questions?...lols ok a dollar a question and Im All set!...
