I've just swapped from a 24mm pwk to a 30mm PHBH on my gt 186 kitted special, I realise I may have more than one problem here....
When I get it running it's running ok(ish) but if I wack the throttle open quicky it dies. It's a bit of a bugger to start again as I think it's flooding, I checked the plug and it's wet! This will probably be the float valve, but will that cause the dying? Currently AV 268, 124 main, 47 pilot,40 slide and x7 needle, second clip down, no filter. Any advice appreciated.

I once had a carb that was massively over jetted. My scooter had no power and wouldn't go up hills. Wouldn't pick up either. I don't know if that's the case with yours, but it's food for thought.

Sorted the flooding issue, and have gone to a 55 pilot and that seems to have stopped the dying issue.

my ts 240 runs a 129 main and av268 atomiser albeit utilising a power jet , so you may be a bit over jetted ......have you looked in the carb section to see if anyone else is running similar

Only on the stand at the minute, but I have looked at what others are running and I may well come down main jet size, just waiting on a new throttle cable.

Try an AV 266 atomiser and a 120/122main you should then be somewhere within the ballpark I would try a 52 pilot X7/X13 needle 2nd clip AV266 120/122 main as a base setting An AV268 is too rich for a GT186 kit.

Having put the 30mm on, it sits on the right hand, but doesn't leave room for my ram air when the panel is on.Doh!

Having just done 10 miles and checked the plug, it was light brown, a little too lean, I think. So I changed the needle from an X7 to a X13, when I started it up it wouldn't tickover and was very smoky! I take it the X13 is a richer needle? Should I have dropped the clip on the X7 rather than change forn a X13? Advice appreiciated. Dave

Needle shouldn't come into it at tickover should it?

Well, Ive put the X7 back in and dropped it down to the 3rd clip, and it seems alot better! So I'll test it and see.
