This is the Featherlite I have. Straight shaft. Runs okay sometimes and sometimes I have to run it half-choked or shorten the lines about half way. Should have taken it back since it has done this since new.I have had the carb apart numerous times and cleaned. Need to be able to adjust the settings, but they are the type that they don't make a wrench for yet, and are recessed where you can't get anything around them to turn them.
