To much advanced timing initialy yes. way beyond 20 mark. Today got it back to 15 std. I think it is ok. Knock/chain noise still there on about 2.5 and 3000 revs when throttle off. Oehh and the hydraulic lifters dance up and down through the bonnet. Horrible. But then again I am happy on the Adj FPR that sorted the big choke situation. Great improvement there. Thanks Jon again. Now the idle problem and that other knocking/chainsaw noises must wait. Will get to them later.
