I pulled the 145 main jets today and put 150s in it. More mid range torque now.. must try some 155s tomorrow...
This 1310 motor is like grandfather's axe- it's had 3 blocks, 2 heads, 2 cranks, 4 camshafts, 2 Weber manifolds and 2 LCBs. Would you believe the
same carb jets have been in it since I bought it 10 years ago.. until today!
<edit> I put the 155 mains in this morning and it goes even HARDER! Seamless power all the way from 2500 up..
Now where are those 160s...
