Why you think I would give estimates without see the equipment. I got though Coleman generator that was brought for repairs they want me to give them a firm repair cost. I couldn't be I had find what was wrong first. Luckily in this case it was just bad fuel and a very badly gummed up carb but it can be worse at times like with the broken deck belt. Ended needing an idler pulley, new spindle shaft, Spindle pulley, and new blades (old ones bent and worn out).
