imola jetting problem

[smoore-gt225]

Hi done search but cant find a lot on my problem
just fitted a imola kit it has a 28 spaco open mouth, 55 pilot, 125 main x7 needle 3rd clip from top av 264 atomiser and a stirling pipe the problem is it will start but as soon as you throttle it dies, now if i start it and then cover the mouth of the carb a little with my hand it revs great any advice would be great

Dunno owt about spaco carbs although those settings look like dellorto, I'd move onto a av266 as I holed two pistons and only stopped when I moved up to a 266. Did you get the piston sorted?

hi i cut the windows in the piston with a dremel and its fine
i took my delly 30 off my other scoot that has a av 266 atomiser and with a bit of playing it is all running fine now although it is miles out on what camlam and others say on jetting it is now 30 delly open mouth, 55 pilot, 148 main, x7 needle 2nd clip from top, av 266 atomiser does this sound about right

148 even the biggest expansion wont run that 125 tops I'd say

it is pulling like a train with the 148, i tried with a 125 and my plug chops were white

id say your fuelling an air leak with that main jet , i had 1 the same with a reed/inlet that needed lots of sealing up

hi looks like a srip down today and recheck everything and plenty of sealant on inlet manifold

hi right i have gone back to my 175 kit for now as i couldnt find what was wrong with the imola i stripped it down twice and couldnt find where an airleak was but it must be from the inlet and all seemed to seal up ok it was always running lean, could it be the mugello piston that i cut windows in be the problem?
