The rebirth of Lazarus
mickwinf:
Will re check timing but was spot on, will keep looking.
K2-K6:
From the plug colour it does seem like its possibly rich enough to knock the edge off response and crispy-ness.
Worthwhile turning the idle adjust screws out half turn ...... to judge if there's significant change or not .... as experiment and investigate evaluation.
Quick and easy to assess effect, free too :)
mickwinf:
so I have gone back to basics, timing is perfect with new Honda points, and reset the valve clearances. There is an occasional spit through the exhaust so I have taken the carbs off to clean again and check float heights. only done one carb up to now, but float was wrong and also the needle was set in the second to bottom groove, am I correct it should be second from the top? that would explain the richness. Carbs are 627b mains 100 slow 40s.
Bryanj:
I seem to remember middle notch for needle which is 3rd from either end
McCabe-Thiele (Ted):
Both my 400 & 500 needle clip is in the middle position 3 counting from either end.
