so i put a different, less worn 30 pict2 on my 1600sp today.
the new carby has one size up on the jets from the old carby.
i figured this was prolly a good thing as my engine tends to run out of puff in higher revs and the stock jets are for a 1300 and not a 1600.
anyway the engine feels a little less sharp on take off now.
would this be the idle jet? if i put the 55 back in instead of the 60 would it help?

Nicko,
Plagiarised from Rob 'n' Daves :
Rob notes -- I have a 1500cc single port engine with it's original 30PICT/2 carburetor. The carburetor has a 55 idle, X125 main and 125 air correction jet. I've used this particular carburetor with a 1600cc dual port engine and it works fine with the same main jet, but seems to like a fractionally larger X130 air correction jet (it runs a little rich with the X125 air correction jet). Others might find that the 30 sized carburetor on a 1600cc engine works better with a larger X127.5 main jet. There is enough variation in fuel types, wear and tear on engine and carburetor, altitude and so on that you might need to experiment a little. All suggestions here are just that - suggestions.
To get you started......
Enjoy

thanks ctefeh, yeah from memory i think the new main is 130 so maybe thats a little big, ill try the stock main and idle jets in the new carby and leave the larger air correction jet and see how that goes.
it does seem like its rich.

I had a 32 pic carb on my L BUG and i put a 130 main jet in it and it goes great now. But not sure of what your problem is.
