Can anyone help me. I have a Stigma 1.6 150 H.P engine in my caterham and anything below 3000 r.p.m the car kangaroo jumps and the only way to stop it ,is to dip the clutch. I find it very difficult either driving through towns or in traffic. I have just had the carbs balanced but that has not stopped the jumping.

Ballistic orange 310sI have the same problem with my Sigma 125 engine. Just learned to manage it. I'd be interested in how you get on.
Hi, Same problem with a 2012 140hp Supersport. I was advised by someone who'd built a Blackbird powered 7 which had a ridiculously light throttle spring to increase the spring tension. I added another coil spring to the top of the throttle pedal and bingo, it reduced the kangarooing quite a bit. It's still there which you have to manage but it's much improved.
