I wouldn't automatically assume the engine is bad. I had the same experience exactly as @mrotto with my first truck mount which had an 18hp B & S engine. That engine was very problematic for me though. If it hadn't been for other troubles with that machine I would likely have just replaced the engine. Nobody I could find could fix it and it was beyond me to know how to do it. I've run into at least a couple guys in my life who were just superb at diagnosing and fixing small engines. Many small engine mechanics IMHO are back yard mechanics who really don't know their trade. I'd look for a good small engine mechanic who has a good reputation in your area and let him check it out before you do anything else.I have a blazer gt truckmount and the engine start smoke bad and lost power , do I need replace with the same engine or there is a way to replace for another ?
The engine I have is and wanguard 16 hp
Know and thanks
