Hey Neil, so I ran my cre b6 pro this past weekend and it dropped it's nut's.
WOW! It's a screamer for sure! I'm running a 2058 with 30/9 byrons and a p3 plug. My issue is the idle is hanging high to the point of the clutch almost engaging with 1.1 springs. It hangs for about 30 to 40 seconds. My idle gap is proper (.5mm) and the lsn is flush. I stopped at flush(I was richening to get idle to come down which did nothing) cause I figured if I had to go beyond flush, I have other issues. When it comes off the high idle, unless you catch it with the trigger, it dies. I'm thinking it dies cause I'm so rich on the lsn. I also think its a leaking front bearing that's the root of my problem. Can I get your .02?
NOTE: It runs great other than the high idle. 220f

Hey Shane, I had the same problem with a Werks B5. It wasn't Clocked but a similar engine nonetheless.
It was a leak indeed but after I replaced my front bearing and it was still happening I had to look elsewhere. I found it to be at the carb/case joint. New O-rings + proper assembly the problem went away. I did end up needing a new front bearing anyway so no worries there.
I'd go ahead and check to make sure the carb is seated and everything else it tight then check the bearing.
Neal has a good way to check for front bearing leaks. With the engine idling on the box spray a little brake cleaner between the flywheel and case. If the engine stalls there's your leak.

I've done it. All oring's where good, not saying one didn't get scarred or ripped when I put engine back together. I will check it out. Thanks for the info...

Linkage is good. Im anal about proper set up. It's a leak, pretty sure. It started doing it after a few tanks of fuel and the outer air filter element was getting pretty dirty. I was thinking, maybe it was starting to choke the engine for air and that might have finished of the seal on the bearing(air took the path of least resistance). I thought the seal was suspect last summer when I ran it cause it was pretty wet around it, but I was running a bit on the rich side yet so I shelfed it and thought nothing more of it. Anyway, new bearing on the way and will inspect all orings and replace as needed.

how much space do you have on your stop collar at neutral ?
