I have my 450 running, which is surprising as it was seized when I got it, but not very well.
New plugs, points, condensers, nice bright blue spark at the right time.
Carbs are spotless, all primaries etc cleaned out, and rebuild kits inc floats.
The bike is difficult to start, will run nicely at highish revs, but as it settles to tickover it dies, seems to need air which leaves me thinking its float heights.....
Can someone confirm is it 20mm to the gasket face or to the body flange?? I have them set to gasket face, which seemed the most common advice, but looking at the card tools they must set it to body flange, which is a 2mm difference.....
