Hi,
Please see attached photo of spark plug after going out today, colour looks better than previously. This is with 45 pilot 128 main & 5899-2 Atomiser from Allstyles. Tried a 50 pilot ran too rich spark plug well sooted up. 48 pilot was better but still felt too rich at low revs. 45 pilot gives crisper throttle response after reseting mixture screw so will leave that as is for now. I am going to do plug chop next as mentioned in previous posts. Have not checked for leak around manifold yet, but will check this also just in case. Thanks again for all the help.
