Years a go my dad gave me a HF 800 watt generator to use boon-docking with my travel trailer. It sat in my garage for 6+ years with 3/4 of a tank of gas. A few months ago I drained the gas and thoroughly cleaned the carb (took everything apart) and put in some of my 2 cycle boat motor gas (mostly fresh). It started right up and ran well (I only tested it with a light) but it seemed to rev high. I would start it every few weeks to keep it from gumming up but the longer between starts the more difficult it would be to start (figured it is/was carb getting gummed up). In anticipation of needing to use it this summer I began starting it each week. A few weeks ago I spray cleaned the carb (no disassembly) and tried to adjust the RPMs. It got to the point where it would not start without starting fluid. I have drained the old gas and put in fresh non-ethanol 91 octane gas with a 50:1 oil mixture. The generator starts well now but will not keep running. I am at a loss for what I should do! Please help.
