The Fel-Pro Kerro-Pak gasket material was ok. It looks durable, but it is hard to cut with razors. It is a paper like substance, not like the hard rubbery type gaskets on many small engines, but better than the cheap happytime corks.
The Tanaka33 fired right up with my boost bottle, idled a little high, but maybe because of the cold weather. When I pinched the hose, it settled down. It was just high enough to grab the clutch some, but it was SMOOOOOTH, and it hauled the bike hard from 5mph to 25mph, didn't get to do over that but it felt like it had some more. It usually does about 28 with this roller, maybe 30 with no wind, with gusto at 20-25mph. Throttle response was instant, rolling it on and letting off.
