Another first for me today. My oldest unit, now 4 1/2 years old, is a Vanguard 18 hp with a 5.6 gpm @3,500 pump. Just had unit tuned up in Feb. Today after 5 minutes of work, it shuts off. It doesn't restart at all nor does it comes close to starting again. Checked oil, gas, air filter, fuel filter -- all right where they need to be and all recently changed or new. Decided to pull both plugs to see that they are VERY worn and black after only a couple of months work. I changed them out with a couple new Champion plugs and it cranked right back up. Sweet!
Not so fast -- after 2 more hours of work the machine had hard time starting back up after I turned it off and when running it sputtered badly and I see a little dark smoke from exhaust. I pull both plugs and the 2 hour old plugs are all black at the business end. I clean the new plugs up a bit and it fired right back up until an hour later and it sputter time again.
What is going on here? Thanks!
