Soprry about all the confusion. Let me try to explain a bit better. The bracket that mounts the high speed idle adjustment to the back of the engine broke off and the fuel nipple going into the the adjustment peice broke off as well. I was able to get the remaining piece of the fuel nipple out and replaced it with the nipple from the muffler. The reason i did this is that the threads are different from an OS to and Evo. So i glued the broken piece of bracket together and took off the Evo muffler and put on an OS muffler i had so that i had enough nipples for all the hoses that needed to be hooked up. However i am having problems with the engine now as it will idle pretty rough and as soon as i increase throttle it bogs badly even with the high idle adjustment screwed in all the way. is that any better?
