The filter was off but I dont see how that would make that much of a difference. I'll put it back on & try it. Also the spring is on there. I did give it gas while it was running to see if if that was a problem but obviously that did not help.When it's not running the throttle moves back & forth as it should no problem. I will ck. the linkage again but I'm pretty sure it is correct. It's 12:30 am here so I will not ck. it out till the morning. Thankx for the suggestions. Will let you know.
