oh come on, you should know what it is, it's painted black and says it's 6HP with OHV's....And people wondering why I am so nitpicking about having all the equipment numbers. With all the replacements of various parts it can be a small wonder if we even get any thing 100% right. IF oem carburetor it came with a soft seal float needle valve which can be even more prone to trash holding it at a point of seepage.
