Hi John yes these are Vertical shaft ones that have had ethanol in them so the carbs are all rusted up so replacement was the only option and at about $12 each well worth the risk. I have both of them working now, so at least in the future I know what has to be done. There was also choke issues but I won't go into that at the moment. BB should be happy I have a couple more Lawn Beetles up and running
