Thanks, mate
The jetting needs work. It’s a Chiselspeed Stage 4 tuned 200.
PHBL25 - throttle valve 300 or 350, pilot 48, slide 45, AQ270/ D29 2nd clip, 102 main. Filter is a bgm elbow with Marchald filter. It feels good, revs up and down crisply except for occasional bogging when accelerating. Plug colour on plug chops all the way through the range are pretty chocolatey brown.
At this point, I am torn between (a) at some point in the throttle progression, it is too rich and the excess petrol is hanging around in the bellows to then be sucked in when I accelerate, or (b) the slide is too lean. If I had an easily accessible dyno nearby, I’d get the air/ fuel ratio checked out.
Next, I am going to try a 40 slide which, I suspect will see me leaning the atomiser, at least.
