The only shop I could find in 100 miles that works on these (2 stroke) just told me water Got in engine. Would not turn over for me even with new battery, neg would start smoki g. Mechanic said he could not hand crank it, looking inside saw h2o around pistols. It ran good last fall, had in garage where temp never fell below 45 degrees. What to do? Shop said they know someone who may buy it for parts, and are trying to sell me a new one... Any constructive advise is welcomed.
