HELP! I i've just bought, what I think is a 305, but really not sure and don't know how to tell.
The problem is that it starts on choke but the runs erratically, revs quite high and then cuts out unless I can give it a bit of choke. I't's been stood a few years. Can anyone help? Does anyone know how many 'turns out' the slow running screw should be? Any ideas??

Have you given the carb a good clean out. With it being stood a while the chances are the pilot jet has been blocked up by the fuel going off.
This a common problem and once cleaned out the bike should run somewhere near. Screw should be around 2 turns out.
Good luck.

Mmm, thanks, I'll try that. Any idea what grade plug it should have?

Save or print these, 305 info sheets, http://s292.photobucket.com/albums/mm22/fa...c5seriesmanual/ I have my air screw out at 1.5 turns on my 305.

Brill, got that. Will print them off. Forum is excellent, wouldn't know where to start otherwise

Also check that the inlet manifold is not cracked or perished - it can give similar faults

Carb is clogged the only reason it runs on choke is that its letting fuel in to the carb. Clean the carb and change fuel line, I had black hose do that exact thing on a 305.
