SH 37 engines
I just picked up this brand new engine off of ebay - of course...
It's an ABC constructed engine with a cool blue head, runs pretty nice, the only problem is I can't get the blasted thing to idle slow enough that it won't engage the clutch! I thought I had it once, but after reving it a little and spooling the blades up I found I was commited to running the tank out.. Wow that sucked, specially since I was just in the back yard and didn't want the thing leaving the ground.. Seemed like forever before it ran out. Oh well. Any ideas anyone? It seems that the throttle lever doesn't close the carb totally, leaves a tiny gap. I'll try to post some pics tommorow after I charge my camera up.. I did mess with both needles quite abit, it wouldn't even start when I adjusted the main needle all over the place. The company who makes this is Golden Lion Enterprise.

Adjustment stop?
Does it have a screw stop like the older OS engines? If the screw that is removed to take out the throttle barrel has a lock nut, then its adjustable.
Oops...

On the bottom of the page you have a pic of the carb, I can't see any stop screw. Maybe you just need to adjust your servo throw.

The servo throw moves the carb as closed as it will get to the point of binding and no dice..
It's actually this one.

If it's an ABC engine , you may not get a decent reliable low tickover until the engine is run in - it could just be too tight to keep going at low speed . That is why I always run ABC engines in on a prop , preferably in a fixed wing model , until they will tickover reliably . However , if the carb won't shut , then that's another issue !At the end of the day , it gets dark .

WooHoo, thanks rf_reggie!!
It does have a stop, I had no idea what that was and thought it was another needle or something. Here's some pics finally and thanks to all who replied and helped me out. I haven't started it yet, but I did adjust it. Here is the before pics.

Here's the adjustment screw

And finally here's after I adjusted it so the throttle will be closed..

Thanks again..Wheeww maybe I can use this sucker after all!! I wanted to make sure pics where up in case anybody else had this issue.

Wow, thats some "idle" gap
that looks at least 25% open. I bet that was real exciting starting up the first time.
