Walbro HD, K-10 HD, K-20 HD kits

[shawn022]

I need to order a few carb kits. Specifically for ms 290 and 440/460 saws. I'm pretty sure I've used the straight HD kits in the past but now see some sellers listing the K-10HD kits for these saws.
So what are the differences in these 3 kits?

I've always used the k10hd kits for those saws. I've been geting all my kits through @Definitive Dave he's got great prices and ships super fast.

Both come with the same basic kit parts, but the k10 offers a couple versions of the pump side gasket, the k20 offers an extra metering side gasket with a different thickness.

Checked out the carb application chart at carbtech21. Looks like k-10hd is all I need. Thanks for all the info.
