I finally sent the converter to Coan , they found a broken sprague , fixed it
Result - car fast again! These bloody things will really make you chase your tail.
Try a converter from a friend ,hopefully a known good piece, I think you might just find the "cure".

This is my thought it could be!

Thank you! You’re absolutely right and although I had the converter cut open and looked at but I know people who said they didn’t take the sprague apart - probably worth shipping it again!!
