I had similar problem with my generator was surging and after watching your video I was able to fixt it just replied the oring Thank you for your video legend
Thanks so much - same issue here, however I notice it smooths out when it warms up. My last shop class that had small engine repair was in 1983 - may be time to take a refresher.
I have a Honda powered Homelight. The only problems I've ever had with it are gunk in the bowl, courtesy of our fine legislators, and a broken governor spring (fortunately makes it run slow vs. blowing it up).
I love em when it's a Honda or Chonda with low oil cut off switches and only the oil is low because most don't read enough to see you literally fill the oil to where almost runs out. Otherwise, yep... it's the air, fuel and/or fire (fire never seen an issue) and the one rare exception was the Champion 4000W that needed the valve lash adjusted. Seems the same outside of H/Chonda'ville designs. I like my type-2 form-a-gasket also when using bad gaskets since amazes me how I can save on that expense that's really only more a time thing if in a pinch.
The best thing to use in Generators if they're being stored is True Fuel or VP Small Engine Flue, no ethanol and it has a very long shelf life. Just wish it was available at the pump, at a decent price.
Long term exposer yes it would. But it is diluted to only 60% and flashes off long before harm can be done. Pure Acetone with out question will swell seals in a matter of minutes but they will shrink as it flashes off.
Acetone burns like a mother. Unfortunately I speak from experience. Before they banned tricolor that was also some nasty stuff to come back at your face.
