Excellent

Excellent service and support. Sales person went above and beyond any expectations I had in helping find proper part for my carburetor.

Have been looking for these needle and seats everywhere. Eric could not have been more helpful. Knew exactly what I wanted, my mechanic is over the moon as he can now rebuild the carburators and I'm happy as we're closer to completing the project. Excellent all round. Thank you
