Ugh. So just got the snowblower back from sears yesterday. We brought it in to get the pull cord replaced (I broke it somehow, don't ask lol) and to have them fix the surging issue the engine has had since it was new. It's a Craftsman 26" (MTD) with the 208cc OHV "Craftsman" (Chongqing Vision Industry is the MFR) engine. Well, they replaced the pull cord, but it still hunts and surges at full throttle. The only way to eliminate it is to adjust the low idle speed screw, which means it can't surge, but there is no idle. It's full throttle or off. I managed to pull the carb off (Hyuai or something like that). And the gasket between the carb and the cylinder head is destroyed. Mutilated. Thinking maybe it was a vacuum leak issue, I made a temporary gasket out of a cereal box. Fixed? Nope. There is no mixture screw. There are two screws on the bowl, but both are strangely for draining the carb. Dunno why it needs two, but anyway. I wonder if it's a governer issue, but I can't see how. It's a few springs and linkages, and haven't been touched since we got it initially. I finally called sears parts and just ordered a new Carbeurator for $28. In the meantime, does anyone have any advice? I'm at my wits end with this thing. It blows snow great, but the hunting surging is an issue. One, it's just REALLY annoying. Two, it hurts snowblowing ability, especially in heavy stuff. Three, It's annoying. Four, I can't imagine it's particularly good for the engine, or belts for it to be doing this constantly. Five, did I mention it's ANNOYING? I've tried carb cleaner. Like I said I ordered a new carb so hopefully that will fix it, but if it doesn't.... Anyone have any advice? Addendum: Oh yeah, and for whatever reason, it ALWAYS needs choke to start. Even if I just ran it for twenty minutes, and I shut it off... It needs at least half choke to start. When cold, it starts first pull. When it's warm it takes two or three, and it backfires the first couple times. Ideas? Related?
