Thanx a bunch for the replies. I didn't record the needle settings when I got it. You know me, Mr. Newbie. Don't know why I didn't. I have on a few other engines. And I'll find out what the carb looks like today. I didn't realize that Novarossi carbs didn't open that much. I'll get a little more aggressive with the settings. Seems like too much though. My truggy will almost pull wheelies with this motor, so I thought I should leave the needles where they are at. I just can't t get the thing to idle. After blipping the throttle, it will idle down in about 5 seconds, hold for about 3-4 and then stall. Thanx for help.
