I recently picked up my first v series mower, a 10301, steel deck self propelled. This is my first experience with a v series and I have a question about the carb. It is a plastic carb and definitely does not have a slow jet like what I've heard the dura forces do. It was warped like the plastic bodies do but it was relatively mild and sanded flat without too much work. My question is regarding the crazy surging this mower has and how to fix it. Since there is no slow jet the typical dura force fix doesn't seem the correct way to go. Another thing is that I'm not sure it has the correct main jet in it either. The jet that is currently in the carb has no shoulder and screws completely into the body, this doesn't seem to be correct based on pics I've seen on the parts breakdowns. Anyone have any thoughts.
