The generator ran a rough test cycle yesterday with lots of backfiring so I did maintenance today. Replaced the plug and changed the oil and filter. I also adjusted the valves but when I took the exhaust cover off to turn the crankshaft by hand i discovered the fan was broken. I don't know how long it has been like that. Ordered a new one for $88 from a place in Alabama. I hope to get it here next week. i also ordered an air filter from AutoZone which is in the store formerly occupied by Apex Ace Hardware. We picked it up after our dance lesson and i installed it. Picked all the tools up and put them in my lawn cart and moved it to the shed until the fan blade gets here. The generator is temporarily out of commission until i get this fixed. In the meantime while playing with it I discovered that i could smooth out the rough idle by playing with the governor. It may be that the idle is set too slow. I have more playing to do. We had a good dance lesson with Robert picking out our music for the Winter Ball . We also learned thhe sliding door Rumba routine as well as forward and reverse twinkle of the waltz. Dinner was Spaghetti, cheese and a hoppy Wheat beer from Sierra Nevada. After dinner i moved the ladder and adjusted the second light. I'll see if this is an improvement. it should be.
