Review: Happy with product - install the driven the correct way. - Due to the direction of the spring on the non-engine size (driven), imo it should be installed as I have in this image. Otherwise, the belt may pull the driven open too soon making the spring seem weak. The balance seems to be fine on both clutch and driven, no wobbles noted. I updated the three springs in the clutch driver to be the comet red series so that the engagement is at 2000 rpms instead of 1600 rpms. Everything is working well.
Review: 40 converter - Good quality worked perfect.

### ⭐⭐⭐⭐ !!!Easy fix for sticking drive clutch read!!!
*by J***N on October 9, 2025*

First off to everyone complaining about the drive clutch sticking I know how you feel. Took me about 10 minutes on the internet to find out why. These drive clutches need to be taken apart and sprayed with a dry molly or graphite spray on the roller surfaces and rollers before use. I had the same problem as everyone else before doing this. I think even Comet has instructions to do this as part of servicing them. Not sure why Blackhorse doesn't do this upon assembly? The only complaint I have, is the clutches wobble slightly do to the clutch halves being distorted in the stamping process when they are made and the belt size provided does not work with the recommended spacing at 9.75 center on center. I had to purchase a Comet 203788A belt. Also, if you plan to run the driven clutch (large diameter) with the spring facing away from the engine you will need to install a yellow reverse wound spring. From someone who was new to this the picture for the listing shows it pictured for a reverse spring which it doesn't come with. If you plan to run it without spending money on a reverse spring the driven clutch needs to face the opposite from what the picture shows in this listing. Hope this review helps.
