I purchased a power stroke 5,000 watt generator about a year ago. Only recently there have been some power issues in my area, which made me decide to take it out and get it ready. I purchased new gas & oil, but it would not start. I tried spraying gas in the carb, and still nothing. Any suggestions?
Most engines don't like to start after extended storage. One cause is a dry cylinder bore which prevents compression.
Solution: pull the spark plug and squirt a generous amount of oil into the cylinder. Like 25% of displacement. Turn the generator so the cylinder is vertical and leave it for a few hours so the oil can flow into the piston grooves. Return it to upright for 30 minutes (so fluids can drain to the proper position).
Very important: Cover the spark plug hole with paper towel and crank for 5-10 seconds. A considerable amount of oil should blow out of the plug hole. Now replace the plug and try starting again.
Three things are required: spark, fuel, and compression.
Some generators have a low oil pressure cut off switch. check if the wires are on it. Check it for continuity with a meter. Look again for a stop/run switch.
I have never seen a generator without a fuel shutoff valve, so carefully check again. You could also take the fuel line off the carburetor and see if gas is making it that fare.
Compression: does it take force to pull the starter rope, or is it electric start? If electric, do you hear the compression strokes. Or does it sound the same as if the spark plug was out.
There are some shade-tree ways for checking for spark that I'm sure you can find on the internet. Don't want to mention here because I will get negative reps for suggesting something dangerous.
Pull cord. Does cord pull or just stop stuck? If stuck, then pistons or cord are jammed.
Disconnect spark plug. Pull cord. Does spark appear? If no spark appears, problem is electrical.
Only thing left is fuel. Cylinders could be flooded, or carburetor is not working or fuel line is blocked. Clean everything.
