Piston uses pump or race gas. We stock parts that are the same quality, price, and have the same specifications from different manufacturers so that when back orders occur, like they have been for the last couple of years, we have an alternate part to send you. That is the only reason your order may arrive looking slightly different from the photos.

We never substitute a cheaper part for an original and if you want a certain brand just ask and we will make sure you get it. Over 99% of people in the world are not qualified to build an engine.

We ALWAYS STRONGLY recommend parts be installed by a qualified, experienced mechanic. If it can not be fixed we will supply you with a new one. The truth is that 99% of failures result from the parts not being installed correctly.

Positive reviews and feedback are greatly appreciated. That could be hundreds or dollars for 1 minute of your time!
