I can see no reason to start another thread, the other one could have been added to.
The 185 pulley has been nothing but trouble from day one as a search would have shown, the search would have also stated the need for a tune etc.
I would have heeded Woodys warning and not proceeded to use it, and the early SC pulleys were a disaster waiting to happen.
Some of the after market pulleys, both the 185 crank and the early SC pulleys have caused a lot of damage to the cars.
