Hey Gadge,
Thanks for the referrals man, I don't really belong to too many other forums but will check these out for sure.
Compression on the AKB is terrific and as I've said before, the carb is drawing up fuel well too. I reckon when we have this maggy sorted, it'll all be downhill form there.
I'm definitely a little concerned about getting into the head to check valves etc as the interior of the hopper is so corroded and with that mess is the bolts to disconnect it

Well, everything else has come undone so far with only gentle persuasion so I remain hopeful that continuous treatment with diesel will suffice until I'm ready

Your school project sounds trerrific .. not enough of it today I don't think. It would certainly keep lads interested rather than sitting still and being quiet lol
