Fitted a new Dellorto 30mm PHBH but only rode it a couple of miles to my sons garage where it has been for 2 plus years.(medical reasons)
Got it out recently, new petrol, cleaned carb, fired up, rode home, went to cafe and back next day, 12 miles round trip pretty good, however it bogs/chokes smokes when pulling away under load, needs a lot of revs to get going but goes well when on the move!
It is a Mugello 200, 42mm expansion and carb is set at 50 pilot, AV266 atomizer, 70 choke, 118 main, x2 needle 3rd clip, remote air filter(sweetbreathe type) which I would like to keep but it does seem better without it!
Checked choke and it looks fine, not sticking. Air screw out 2 turns. On stand it starts first/second kick, ticks over, revs up fine but a bit of smoke at low revs!
Would appreciate any advice, not sure if is it rich/lean? I have other jets/atomizers and needles I can use but not sure where to start.
Thanks
Apologies for long post!!
