Asking for a buddy of mine, hoping to get a good starting point .
150 super engine (totally rebuilt)
Std crank (with electronic taper)
DR180 (just chamfered ports no more)
Sterling pipe
Std 20/20 carb
18° static btdc

What should we be looking at jetting wise, as we built this engine from bits from collective garages and are a bit unsure where to start?
Thanks in advance
Tony

I`ve done a few with SIP Road pipes, standard jetting apart from an increase on the main to 108.
With the Sterling maybe start a bit higher 112 and work down.
