A few months ago I picked up an 89 Mighty Max. She ran great for a while and is now showing telltale signs of carb trouble. I'm taking it off the engine to rebuild it and I notice a huge pile of what seemed to be bondo on the back side of the top layer of the carb. As it was coming off anyways, I scraped it off to find that it covered a few oem holes. Attached is a picture before and after I scraped the stuff off.
My question is this: Do any of you have any clue why someone would put all this on here, over these holes? According to my carb rebuild diagram (which admittedly isn't very detailed), it doesn't look like those holes are supposed to be covered. Even if they are, theres more effective ways to plug a hole like that than slapping bondo all over the side of the carb :l Any advice you guys might have would be greatly appreciated.
