Thanks Tyler and Max.
The reason I asked was because of advice given about the Masport Whirlwind tiller gearbox on ODK the other day, just thought the HTB I've been using for almost everything for years might not be suitable for the b/c gears after all.
I have about half a 500gm tub and an unopened tub so it might be a while til I try the teflon stuff ;-)
Doubt those gearboxes would work with the Honda which has a much thinner rectangular end on the driveshaft. Haven't priced a new Honda gearbox but suspect it would be a LOT more than $22.
