Your idle issue just seems like the anti-stall spring isn't tensioned enough, and its relying on the actual throttle cable to maintain the idle which is a bad idea because it can move about and stretch when the engine rocks adjusting your idle. Have you tried to adjust it on the back of the pump? If its not got the spring in, then that will be the cause of your idle issue, but if it has make sure your main throttle is slackened right off and adjust up your idle using the anti-stall which will keep it stable.

makes me think I should have kept the forged rods out the last engine ?

I'm gonna guess at about 159hp/265ftlb.

Great to see you are back on the XUD scene, buy Toms remaining set of forged rods!
