Hello and welcome to the forum. Where in Colorado are you?

You problem might be the chain jambed in the sprocket and clutch actuator cover. If the chain tension is too loose this can happen. Remove the cover, the one on the left side where the clutch cable attaches, and take a look at the chain/sprocket.

We suggest against using the advice given in the kit instructions regarding fuel/oil mix. 16:1 is just a little heavy on oil. Try a 24:1 mix then move down to 32:1 after break in.
Get back to us with what you find. We're here to help.

that happened to me on a pk 80. the needle bearings broke.

I rode the h3ll out of that engine so the damage wasn't surprising.

Yeah, the instructions that come with these kits are crap, all the info you need on installation and running is right here. :) Good luck on your problem, sounds like something is locked up in the engine, but not the clutch. Have you tried taking the spark plug out and doing it? That would help us figure it out easier, but sounds like something is locked or jammed. That can happen in these little engines, you might have gotten a dud. :(

We all posted at the same time it looks like. LOL, the fact that it is so new leads me to beleive the engine was a bad lemon. It happens...

It depends what is wrong, usually if they lock up, something is wrong, check the magento for jamming, then the to gear on the right side for any visual jamming. Check the teeth on it. If it's not that, then try taking the head off and look for damage, then the jug, if you can not get the jug off, it's the rings, I assume the piston is not moving. If the jug, piston, and rings are OK, then it could be the bearings inside the case, like vtec mentioned. Just search around and get a basic knowledge of the layout of the engine and start tearing down until you find the problem, if you don't want to dig that deep, you can always get a new one. Somewhere on here is a 3D animation of the engine, if someone could post a link on it, that would be great. Good Luck.

Sorry,
I misread your original post. You're right about the clutch.

How old is the engine? Is it in warranty by the seller? Don't start taking it apart until you've contacted the vendor you bought the engine from. Disassembling it might void any warranty you had.

If no warranty then take Vista's advice. Remove the cylinder head first and look for damage in the cylinder walls. Broken piston rings are not uncommon. If the top of the piston and cylinder look okay inspect the gears on the inside of the cover on the right side. If all looks normal there go ahead and remove the cylinder from the case. The piston rings will expand when the come out and will need to be carefully compressed again to put things back together.
Check with your vendor first...I hope you bought your kit from a reputable one.
Let us know what you find.
Tom

Just because it was running good before doesn't mean something was wrong, a bearing or similar could have been made wrong and it didn't break until now. Anything could have happened from what we know at this point. Just do what I said earlier, take your time, and come back with the results. Good Luck.

Okay, cap'n obvious here. . .spend an evening pulling the engine off and pulling it apart. if you've been having problems with the wheel locking up it's gonna get really obvious. I recommend a fresh pack of smokes and a fresh pot of coffee. A camera for a few photos along the way wouldn't hurt a thing either.
