Hi guys, I’ve had a set of 34 ICTs fitted to my motor a little while back, the engine is over revving between gear changes and when I stop the revs sit between 1500 and 2000 rpms. I had the timing and the cards checked out and all’s well. It just looks like the springs on the carbs aren’t man enough to return the revs back down. So when I stop I go round the back and turn the Bellcrank slightly and that does the trick. So I’ve got myself a CSP return spring as I’ve read that should sort the problem out. So my question is how difficult is it the fit, does the Bellcrank part as it looks like the spring sits between the non moving part and the moving part, any help appreciate guys. The engine is a Type one with twin carbs
