You could try one of these.

I bought a .325 X 7t kit for a Zenoah 3800 from this guy and it's been great.
Thanks for the link. My problem is now that while the sprocket I have (Oregon as above) takes a rim in 3/8 (or .325) there does not seem to be a 3/8 x7 low pro rim available to suit. The Chinese seem to ignore the difference even from new, but the fact is a low profile rim really needs to be a bigger diameter than its 3/8 standard equivalent, other wise all drive is taken by one drive link at a time ,rather than 3 or four, which is (technically) very incorrect. (but in practise works)
I do however have a Chinese spur type clutch with 3/8 low pro rim to suit for a Stihl 018 etc. However its 3/8 low pro rim (bigger dia ) does not fit my Oregon spur sprocket. BUT, would you believe, the 018 spur sprocket fits the 2036, bearing and all. the od of this clutch drum is however around 2mm bigger, so while clutch shoes have a little further to travel but seem ok, it would be necessary to doctor brake band to get clearance.
I have sufficient experience to notice that the actual spur is bronze welded into both but if I swapped them over the heat I would need would undoubtably trouble the tempering of the surface for needle rollers........
But maybe not ! Right now I don't have the inclination to be bothered, so it is running a 3/8 low profile chain on a 3/8x7 Chinese rim (with 19mm hole) as they handily advertise. (as suggested previously, it seems to be fine), so I shall feign ignorance. Fortunately, there are not likely to be any smart Alec's pointing out my error where it is currently at work, and if there were, they would be put to work regardless dragging blackthorn and sloe branches (with unusually aggressive thorns prone to staying just under skin till good and swollen) up a steep wet bank to where I can get to them with a tractor sweep.
Good chain speed, light and cheap however, with room in handle for good gloves.
For me it still begs the question, why no 3/8 low pro rim for this particular hub ?
