i am having a problem with a 52" belt driven Bunton w/b and was wondering if anyone has a suggestion before i take it to the shop. Here's the deal: The mower runs wells at idle. However, when the blades are engaged there is a substantial loss in power. If the mower even touches light grass it boggs down almost to to the point of stalling. When this occurs there is also a strong odor of gas. I'm no mechanic but i have taken most of the mower apart and am stumped so far. We have other mowers, but this an essential spare for my other crew. Any suggestions would be greatly appreciated cause i'm trying to save a buck by fixing it myself.
