Customer Question
Hi, I have a...

Hi, I have a generac 6500 watt generator with a Briggs 10hp gas engine. Has always run fine. Cranked and ran it for about 10 minutes the day before we got a big storm and it ran perfectly. The next day, I tried to crank it, and it only backfires and will not crank.

Mechanic's Assistant: What's the make and model of the generator? And can you guesstimate how old it is?

It is around a 2003 model. It's called "Power Storm", I think. It is either 5500 watts or 6500 watts with an 8500 watt surge.

Mechanic's Assistant: Do you plan on doing the work yourself?

If possible. So far, I've drained the carb and checked it for visible debris, and I've changed to a new spark plug. The gas was shut off and I let the engine run out the gas in the lines the day I checked it to make sure it was running fine.

Mechanic's Assistant: Anything else we should know to help you best?

No, just advice on what could be the problem. Thanks
