Bigger jet is back in. I just looked at the plates, both have a completely flat bottom, my original had a little smaller taper for the idle screw so I put that one back in, no change. I’ve been riding it good the past 2 days, runs great except for idling. As far a compression I don’t think it turns over too easily. How would I tell decompression leaking? This is pretty much my first dive into things like this so forgive me. Thanks for the advice!
