I purchased a 22-kw generac generator and it worked fine for about 3 years and at some point it wouldn't start. I had 3 different authorized dealer repairmen work on it. The spark plugs were changed at least twice, plug wires once, carburetor, was changed out, the choke assembly was again changed, the magnetic pick ups were also changed and still after all of these changes it still ran poorly.. During a repair service call, a service tech noticed a diaphragm which had openings to allow air the activation of the fuel to flow to the engine was clogged with dirt and he removed the mud and the unit started up immediately. The air diaphragm is located on the right side at the very bottom of the unit with air vents allowing water when it rains and dust from mowing the grass to enter. To prevent the system from clogging I cut a plastic gallon water bottle in half and placed it over the diaphragm and it has run great ever since. I called generac numerous times when the unit wouldn't run so I felt it would be the right thing to do as to inform them what they were able to cure the issue and wouldn't you know it, they voided my warranty. I would estimate that generac had spent an excess of 5 or 6 hundred dollars for the tech and several hundred more dollars for parts. This is now the 3rd year sin I used the plastic bottle and the unit is and has run great every time we have had a power outage.
I purchased a Generac generator about a month ago and the purchase and delivery were easy. Factory Pure was the best price out of 5 vendors I shopped. Delivery was about 7 days after I purchased the generator and a date and time was set by the shipper.
Easy to talk to and explain everything
Was packaged perfectly and not one problem, delivery company was also exceptional
Great service at great prices!!!! Thank you from Hanover, Ma
