I found a couple (2) of used Homelite weedeaters for sale locally for $20.00 for both. The seller says one runs and the other needs a new fuel line and should run. I have no expeience with engine conversions but am facing a long boring winter. I have no idea what size the engines are but I'm thinking they're worth the $20 no matter what . Shall I go for it? Where might I find prop hubs/adapters for these? Thanks in advance
