Don, I know what you mean about trying to find cub parts in this area. I'm across the straight in New Westminster, B.C. I spent a whole day running around the valley trying to track down the original dealer in the area - no luck. Just when I told I had hit pay dirt in terms of who now has all the old cub parts I found out that there were only IH push mower parts.
You can get real Hy-Tran and filters from Central Valley farm (Case IH dealer in abbotsford).
As for your carb...my 129 did the same thing - I took the carb apart carfully and cleaned all the little passage ways - pay clode attention to the float needle as they seems to get gummed up with old gas and cause the gas to run out as you describe.
You can get gasket material from princess auto to cut yourself a new float bowl gasket.
The sponsers (boxes at top of forum) have complete kits listed.
