I have a splutter when the throttle is fully open?

Hello
I have just swapped carbs on my Rapido 250. My phbh 28mm was leaking fuel, so I went for a VHST 24mm. I thought I ordered a 28mm version, but one too many Stella's last Friday and, hay ho, it ended up being a 24mm. I am not complaining though, as it seems to pull just as well as before.
I have had a reed valve (LTH) fitted and a bgm clubman V2. I have increased the main jet to 155 now from 140 and swapped out the needle and all the other jets from the old carb, except for the atomiser, because it's a different size.
It runs great and I have done a few plug-chops and all seems nice and brown, although it's maybe a little too light in colour for my liking.
The only problem I have really encountered is when I was pulling out into fast traffic, I opened the throttle to the hilt and it spluttered. When you back off a bit it runs great again, but it got me a bit worried.
Any ideas?
