Default coaster brake issues.

I have this onyx 29 inch moto-bike.

My question involves the coaster brake. For some reason after I took it apart the it has started making the pedals turn just by moving the wheels. Nothing so serious that it's like a fixed gear, but when I put no pressure on the pedals they will move with the wheels movements. lightly and they will stop if i have my feet on em.

Did I tighten the coaster to tight or something? Do I need to have the coaster set in a certain position before installing? (I have the internals of the coaster brake assembled correctly, at least in the correct directions/placements) I'm sure I could have solved this by now, but this extra chain and the inability to put my bike on a stand is kicking me in the face.

Just post me a link of a youtube video that shows the do's and don'ts of reinstalling the rear wheel, cause I seem to be screwing it up.

yeah I've loosened the entire assembly a bit and it stopped the issue but it cause the rim to wobble on the bearings. Maybe I need a bushing/washer or something...

Maybe now you are just too loose, you may just need to find the sweet spot?

yeah, you gotta find the sweet spot.

when the cones are too tight it puts pressure on the drive sprocket, and that causes it to pedal forward. cones too loose and it wobbles.

it just takes some patience.

Check to see if the dust cover cap is pressing on the bearings

Find the sweet spot and get the adjustment bolts tight against one another.

Get the wheel on the bike, then before tightening it into place, turn the whole deal until the brake arm is up where you attach the band around the chain stay. Now Move the wheel back to tension the chain. Finally tighten it all up.

Do not move the brake arm into into place with the axle nuts tightened.

A bike shop, if you bring in the wheel only, charges about $10-$15 for an adjustment.

Mount the brake arm loose, so it doesn't spin. then adjust the wheel for chain tension .

Cone adjustment wrenches are an almost must have when trying to get this right. I finally had to break down a get a set for mine.

Good luck!!
