Not good
Hole for linkage too small and diaphragm rubber poor quality. Dry cracked and had a hole in less than a year.

Poor fitment
Hole is drilled off center and wouldn't fit over the secondary lever pin. Had to carefully drill out the hole in the rod oversized as the hole wasn't centered. So be prepared to do a little work to get them to fit.

Poorly made
Cheap cheap cheap! Picture in post doesn't match actual product. Had to file mounting hole for throttle shaft bracket before it would fit will not purchase again. Cheap Chinese knockoff. Spend the extra $5.00 on a better product. Cheap Cheap Cheap!

Junk
Super thin hard to get to seal. Not like the original that has a fat flange made up of multiple layers. The hole in the shaft was too small and needed drilling out.. JUST RUBBISH
