Rated 3 out of 5 by from Good product but part issue needs to be corrected Bought my Cosense GP 6500 in October 2018 after Hurrican Michael knocked out our power for 2 weeks. Fast forward 2020, I went to start the generator to let it a run a few mins. Did the pre start steps, opened the fuel valve etc...and as soon as I started pulling on the crank, fuel began to flow out of the bottom and sides of the carburetor. Did some research and find it is a common issue with Generac generators...the culptlrit appears to be the float and the needle valve pin. So now I have to decide to try and fix it myself or take it to someone. Very frustrating especially with this being a common part issue....

Rated 5 out of 5 by from Easy to start! Bought when power went out in early august. Ran 2 fridges and a chest freezer without a hiccup! Recently had a transfer switch set up so now I can power the whole house if I want to. Starts on first or second pull every time, and has enough power to not strain at all.

Rated 5 out of 5 by from This product is very easy to use Just purchased this product a few weeks ago and me my wife love the easiness of use and performed as advertised. Would recommend it anyone that faced the same situation as we were, going thru two hurricanes back to back three weeks apart. Thanks Generac for such a great product.

Rated 4 out of 5 by from Great value BUT ... Great bang for your buck! Typically starts on first easy pull, runs smoothly, and produces enough back-up power to run my whole house ALMOST normally! Would have been 5 stars EXCEPT for the sensitivity of the COsense system. Placed outdoors parallel to the building at a distance of 6 feet, the unit runs for 5-7 minutes and then COsense shuts it down! Need to place the unit exhaust away, perpendicular to the building and at 9 feet away! Also, the assembly instructions, while straightforward, lack detail. Three holes for handle mounting but no specification while one gets the bolts and what are the four plastic washers for? NO mention of them at ALL!

Rated 5 out of 5 by from Trusted Power Just bought gp6500. Didn’t take long to set up. The power came back on before the generator was ready but I did shut power back off and tried the generator for backup power and it worked just great. I will have to do a follow up review the next time the power goes off. I have worked in the industrial industry for forty years so I know that Generac can be trusted. I’m sure I will have this generator for many years.

Rated 5 out of 5 by from Definitely one of the best purchases I've ever made ... I purchased this Generac during the aftermath of Hurricane Laura. Pro's: Very little assembly was needed before it was ready for service. Excellent quality of construction. Has a good set of features to make it easy to use and keep it in service as long as it is required. (Fuel gauge, hour meter, and quite a decent sized fuel tank) Con's: Pull start only. (Not necessarily a "negative" as there's no starter system/circuit to worry about going out, and no battery to maintain in the off season) The engine can be a little noisy, but with proper/common sense placement of the unit this can be mitigated. The COSense system can trip itself if you place the unit's exhaust near a wall or if the unit is in the corner of a building where the breeze could keep the exhaust from drifting away. (In other words, it's quite sensitive ... so keep that in mind with placement). Overall: It's not the cheapest generator, but in this case... you honestly get what you've paid for. If I could go back in time and have the choice of buying it again, I absolutely would. So far, I'm 100% satisfied after the very easy initial setup and figuring out the best way to place the unit to keep it in service. The unit does what it's supposed to, and has been worth every single red cent since it's purchase. Keep up the good work Generac, and please ... whatever you do, don't stoop to cutting corners like some of the other manufacturer's whose generators I've used before have in recent times. Sincerely, A satisfied customer named Stephen

Rated 5 out of 5 by from This product has great features This product works, quite noisy for such a small engine but it ran perfectly for more than 2 days.

Rated 4 out of 5 by from Worked Louisiana doesn't require the emissions control features this generator has. The only reason we bought this generator was because it was the only one available that day. Would have preferred a less features, however it worked like a champ.
