Just finished rebuilding my comet NWB 101 after it being in bits for a number of years, although it runs nicely(i think) It seems a bit lacklustre after 50mph I feel
the valve timing is out as on tickover a thin mist of fuel comes out of the carb bellmouth.This is what i did to time it with unmarked pinions.
1, find tdc firing stroke 2 ,turn engine back and then forward to42 bTDC,3 after
slackening tappets and ensuring breather pinion was in correct position turned
camwheels so inlet valve was just opening.4 fitted halftime pinion and key into
nearest aligned keyway.5 turned engine back to38 deg BTDC,spragged ATC to
full advance with points just opening and fitted same to Mag.
What have I done wrong if anything your comments would be appreciated before
i take the timing cover off again. alan
