What jet should I use??

I have an '85 spree and recently ordered the mlm side bleed pipe and polini cp 15mm carb. I feel I should re-jet the carb straight away. If this is true, what size jets should I use?

I can't tell you the jet size.
The important step is to take time to do plug-chops and adjust according to the results.

Ok thanks, as soon as I receive the carb and throw that on I'll for sure do that. I only ask because with the stock carb it's recommended to upjet with the mlm pipe. So I wasn't sure if it was needed with the new carb.

Nobody knows what size jet size is in that new carb.

A 15mm carb is 2mm SMALLER than the stock carb which is a bad move on a Spree. Go back to original carb.
