Would air in fuel lines before the pump cause issues with carb? see photo for reference. Engine is a Honda BF5 I picked up. 

This is for an outboard engine. it seems to have a bad idle and die under throttle, and wouldn't start the last few days until today. After running for a while it seemed to be a bit better and could take throttle. 

New aftermarket carb (original had damaged idle screw stuck inside and broken, but seemed to have same issue), plug, and fuel lines. Tank is old so possibly that.

Thinking of picking up these advans, owner has them as RSii. Trying to figure out of if they are legit, the shape and details look good to me but they don't have any stickers in the barrel. I also can't see any Yokohama branding. Any opinions? 

Avan RS -reps or legit?

1959 construction, board around HVAC registers (supply side). Ontario. Wondering if there's any reason to even test this or just presume it asbestos and save the money testing.

Wall coating I've also tested (PLM) and was negative which kind of surprised me.
