I bought a Ridgid 3300 yesterday. I used it for 4 hours yesterday and 6 today. It worked great for these first 10 hours, but then the engine went into an oscillatory state where the throttle backed off, then went full bore, then backed off, and continued doing this for about 10 seconds, backfired a couple of times, and died. (Normally, I think the throttle is at idle until you squeeze wand trigger, at which point it goes full bore). I could not get the engine to start again until allowing it to rest for about 3 minutes. After restarting, it ran fine for about 3 minutes and started doing the same thing again. The next time I tried, I released the wand trigger when the engine started doing its idle/full/idle thing but this caused the engine to quit almost immediately. This same thing happened about 4 times at which point I let it sit for 30 minutes, came back, and tried again - to no avail (same problem). Anyone else have this problem? Anyone know what might be causing this problem?
No announcement yet.
