Default Turnigy 32 Running Rough

I've got a Turnigy 32 that I bought new and am having an issue with it not wanting to idle and when I can get the rpm's down it runs very rough (quite a bit of vibration). I changed the carbuerator out from the original Tillotson to a Walbro thinking that may have been part of the issue, it wasn't. Mid Range to Full throttle it runs very well but at idle it vibrates excessively. The prop is balanced and I am using fresh fuel so those can be eliminated as the problem. I am also using a rear dump muffler that I bought for another 30cc but it fits perfectly. Sort of at my wit's end on trying to figure this out so I thought I'd see what ideas you all have.

Happy Flying!

Thanks, the plug is fresh and gapped at 22. I thought about the ignition as well and may give that a try.

Happy Flying!

These things, not just the RCGF, but all of them in this size range, vibrate a LOT more than what some are prepared for when getting into gas. So not meaning to insult anyone, just wondering if this is your first gas engine?

Are you running the plane without the wing installed?

You might need to set the timing. There are videos on YouTube that can guide you.

Nope not my first! The engine at idle is way too rough. Mid range and top end are fine but will not idle without shaking the bejeezus out of the airframe.
I also suspected the timing but after checking it's not the culprit.

Is the engine on a test stand? What about the wing? Post an image of the engine mounting. Dan.
