I’m running a Polini top end on a T5 motor with a flowed crank, Simonini and 21 tooth Clutch. I’ve the 24mil carb on and it’s way too weak top end. I’ve now got a 130 air corrector, be2 atomiser and a 150 main jet, I’ve tried a 120 ac but it’s way too rich and I just don’t get the delivery.
I know it’s a huge main jet but it seems to need it and it’s still to lean top end as it likes to seize.
Timings on factory setting and the plug is well hot.
I’d appreciate some help as Hollands getting way too close.
