Hello,

I have an American Sportwork Trail Wagon 265 with a Subaru engine. The rear clutch CVT (Driven Clutch) is rotating while the unit is sitting still, in neutral. It is causing putting the unit in gear to be difficult and even shut off at start off.

What is the best possible solution to resolve this?

Thank you for any advice!

Not familiar with that engine or machine.
Some of the ASW small machines used a "GY6 style" engine and/or CVT
The GY6 CVT is different than let's say, the Comet style

Comet doesn't have an actual clutch.
The drive pulley functions as a clutch

The GY6 style does have an actual clutch
It is a centrifugal clutch piggybacked on the driven pulley

A big difference is that on the Comet style the belt does not turn at low rpms.
The drive disengages and spins without turning the belt.
On the GY6 style, the belt spins all the time that the engine is spinning, regardless of rpm's.
Because the clutch is after the belt.

So, what kind of CVT do you have?

According to the American Landmaster site, I have the one with the CVT Driven Comet.

Yeah, that sure looks like Comet
The belt shouldn't be spinning at idle
So:
High idle
Broke drive pulley not disengaging
Wrong belt
Wrong pulley spacing c-c

Sometimes if the load is removed, like the driven key sheared, the CVT might have enough grip to weakly spin the belt.

I have a Bristers chuck wagon 265cc. The engine has been changed to a powerease 420cc just bought it. Iam having the same problem. It had a A-300668 on it when I got it and the driver pully didn’t turn but the belt was stretched and frayed and when you put it in gear it would jerk you real hard and dies. I called landmasters and they said the belt that goes on it is a 2.20693 so I ordered it and know the driver pully turns when idling. I did idle it up some before I put the belt on but Iam going to idle it back down to see if that helps. The distance from the driver to driven is 15” and the driven pully is 7 1/2” it’s the same set up when it had the Subaru engine in it. Maybe some of this information might help. Could you let me know if you come up with anything. Thanks Steve .

I have a bristers chuck wagon 265cc. But the Subaru engine was replaced with a Powerease 420cc engine. Having a problem when putting in gear . The belt turns all the time and when putting it in gear it jerks hard and dies. It had a old belt on it comet: A-300668 that is stretched and frayed. But the driver didn’t turn with it . This new belt I ordered from Landmasters replacement the comet (asw2.20693) . This new belt the driver turns at idle. Also when pushing on gas peddle it back fires. Can you help. Thanks.

I'm not sure how a Landmasters part will match up to an engine swap?
And I don't have knowledge on the proper part numbers.

There are several factors dealing with a CVT setup.
They involve the clutching function as well as the various belt/pulley ratios
I wonder if Comet covers things like this in their in-depth service manuals?

Here are a couple of the adjustment/setup specs from Polaris.
The numbers might not be good, but you can get the idea.
The side gap has a lot to do the clutch function.
A gap equals clutch disengaged, no gap equals clutch engaged
Belt deflection (tension) affects belt creeping.

I have the same Subaru 265cc trail wagon, I need the driver clutch, or parts for the driver clutch. Any ideas where I can get that pretty reasonable?
