    Somebody must've dinked around with the clutch linkage when they replaced the clutch.

    I thought Prostars had hydraulic clutch linkages.

    Sounds like it’s not adjusted right. Free play should be 1.5”- 2”. Clutch brake should engage about an inch off the floor. Maybe they turned the flywheel, or swapped it with a thinner one, and you need an oversized clutch brake. Adjust clutch, getting proper gap, making sure clutch brake engages. Check linkage for slop. It’s either going to work right, or need a thicker clutch brake, or has worn linkage parts.
