crud
Yuh, I removed my tank & washed it out with 5 litres of acetone, which was harder than it sounds. My reserach suggests that alloy tanks need no liner (steel do) but someone had put vast amounts of sealer in there, most of which had settled in the reserve area of course. I got flakes & chunks out but some remained even after 2 weeks of this cleaning.
I blew out the lines by mouth & tyre compressor, probably not very well. Rebuilt the fuel pump, cleaned the gauze filters in the pump & to each carb but did not strip the carbs. New coil, condensor, contacts, leads, plugs & plug caps.
It fires up better, and runs sort of OK to about 60mph but gets pretty fluttery then, misfires a bit, smokes too much & the plugs oil so I have improved things but not fixed, dammit. The oil makes me feel my next task is a compression test to see if I can work out, is it rings or is it valves? Great.
