Thanks I appreciate that. Mine came so worn out an really loose I'm thinking someone put the wrong one on it

The belts for them are no longer available. What I did on mine was measure the center to center distance of the drive and driven and the diameter of the driven. I found a Comet belt length chart on line.
They don't have one that fits but I got the one that was a tad shorter than needed.
I drilled new engine mounting holes further back on the plate to get the center to center distance correct. It worked Great.
You can't move the engine too far back as you run out of room to get the right rear bolt in. I used an allen head bolt and inserted it from the bottom up and put the nut on the engine side. It worked well that way.
Sorry, I sold the bike so I can't get the belt number for you...

I could not find the correct part # on mine to match it up with,but other than it being somewhat worn it still worked ok so I would be willing to send it to you to match it up with a new one as long as I got it back. Probably only a few dollars each way to send it.

First of all... the clutch isn't fully closed. The the buttons need to be touching the helix at the bottom of the helix

The driven clutch needs to be dismantled, cleaned, inspected , reassembled and checked for calibration. That's when you will know weather your belt is the right one. Obviously you can't do all of this without doing the drive clutch at the same time.

I'll be needing to research these parts a little bit and figure it out. Not much info on the web about trail flite. I'll look up clutches as well

With the belt removed the driven clutch should close much tighter. Also, and this is important, when the belt is off the outside sheave of the clutch should have a rotation tension also. If you turn the outside sheave clockwise, it should spring back counter clockwise with a snap.
When you take it apart to clean it you have to wind the spring a little bit. You just need to wind it far enough theat the buttons will stay in contact with the three towers. perhaps 120 degrees of rotation when you put it back together.
The way yours is in the pictures your minibike will have good top end but really slow out of the hole. Correct the driven and you will notice a big improvement in acceleration and low speed riding.
Your belt should be loose but now where near as loose as shown.

It is definitely going to need to be taken apart. It has very little spring back tension and actually feels a little loose
