The tank that I used was brand new, bought it as I tanked the gas. Mixed the oil and in it went. But as said, its working now (I believe) although not anymore under my feet so I dont have to worry this anymore.

Just wanted to explain thoroughly what I experienced and stress that although this happened to me, Im not complaning Beta in general as I have always find it being one of the best. My friends bike was perfect from the beginning, many though have had problems with carb settings and float level as the bike stalls when in angle. Actually I noticed my problems first time when I pumped the front suspension and in a second it just died... every single time it was either in angle or suspension was pumped and not like after a while but not more than than a blink of an eye. Just simply stopped running. We cleaned the carburator several times, checked the needle position and adjusted the float level. Changed different gas, even drained the fuel system and filled it from another gas tank. And also changed the oil mixture from 2% to normal 1.5%. Nothing helped. We opened the reedvalve, changed carb throat just to be sure (btw, this is so thick that its hard to even imagine it would brake under stress of taking the carb of or putting it on. Maybe after many years or when -20 frost but not in normal conditions). Im not that technical, but I believe we did almost everything there is to do with my bike. We also checked the crankshaft gasket and timing. Local importer was very helpful as said, so I believe nothing more I could do about this.

Well it sounds like you worked the problem. Sorry you couldn't get it resolved. Here's where you get an idea of the engineer's mindset. For me that sounds like an irresistible problem. The kind of thing I find fun and can focus on to the exclusion of almost everything else until I have it figured out.

You can access the clamp nearest the airbox from the side by positioning said clamp so that it faces the triangular cut out on the frame just above where the rear brake assembly bolts to the frame. Put your hand underneath to hold the clamp as it is loosened to stop it rotating away from your screwdriver. The other clamp nearest the carb can then be loosened and the airbox to carb rubber boot slid back towards the airbox and clear of the rear of the carb.

Squirt a bit of WD40 (other lubricants are available) on the joint betwixt airbox and boot to aid slideage.
