Finally got my N15cs running. Engine has been completely done, a lot of the work by Norman White. The mag has been rebuilt by NOC magneto specialist Paul Wolf. New monobloc carbs, cleaned and blown out. The bike starts easily and ticks over nicely. However, when put under load it misfires and splutters, hardly able to pull the bike along. On blipping the throttle it will over run. The timing is set (and checked) at 30deg. The AAU seems very stiff and is reluctant to return to its retarded position. The chain goes tight and loose but even in its tight mode there is still slack. If I remove the chain and just put it on the mag taper it snaps back nicely, as soon as the chain is on it is stiff. I've put on new springs and cleaned it as thoroughly as I can. Any ideas? Even how to dismantle it would help.
Thank you in advance.
