Guys- Went to crank up my Honda Harmony. Refused to start. Took apart the carb cleaned it put it back together. Replaced the plug. Still no go. Has good spark and clean air filter. I Took it to the shop and was told the mower has no compression. I have a hard time believing this. It had no prior symptoms, oil burning or hard starts. The failure was sudden. The mower is about 7-8 years old and I have no idea how many hours are on it. Thoughts???? I hate to part w/ my H\onda Harmony- been a good mower and very reliable.
