re: Converted my generator to natural gas in about 30 minutes

I’ve converted three generators with kits from US Carburetion. All were easy to install and works great. No more chasing gasoline as long as Atmos can supply natural gas reliably!

I have the same light plant. I did mine like that for Gustav and it's been kicking arse since. I ran my whole house for on it for 16 days for Ida without issue. Breaker tripped one time because my wife was trying to wash clothes with 2 window units, 2 freezers and 2 ice boxes running.

Great post, thanks for sharing. Well worth it. What is the guess as to what the lower output will be?

Just an update on my conversion. I ordered a new air intake manifold gasket, air filter, etc. and so had to wait until they got in and I had time to mess with it.
My generator doesn't have as much clearance between the air intake housing and the frame. Adding the natural gas orifice insert pushes the air housing into the frame itself once fully assembled. I had to trim the left side of the housing so it would fit without damaging the screw hole so I could still tighten it up. So, the 'open lip' might allow more air to enter in on the left side but it was the best I could do.
Mounting the regulator was also a pain because there is a heat shield that did not allow me to directly bolt to the outer plate metal. I may be a shorter bolt and see if I have enough clearance to get the nut on, but I'm not optimistic about that. I just drilled through the heat shield and bolted it to that on one side. I'll probably be revisiting this, but we'll see how it goes.
The PVC tube to extend the vacuum tube was loose when inserted so I bought a couple of hose clamps for that and it I think that'll do it.
My kit didn't come with quick connect gas fittings so I'm going to have to buy some of those along with a hose and give it a try. Will report back, but might be a while.

Whar generator do you have? I didnt have those space issues.
I added this adapter to test fir leaks with a shorter hose. It fired up on the 3rd pull and no leaks. This guarantees no more louisiana hurricanes this year since I am prepared.

Troy Bilt 5550. The air intake extends past the frame now and you can see where I had to trim it. Every video I watched they had plenty of room. I guess mine was an earlier model.

Great post.
For those folks out there who have smaller generators...I just converted my dads older Generac 5500 to run on NG. I bought a carburetor off Amazon for $33...swapped it out...plumb it up and it fired on the 3rd pull.
Seemed to run smoother. It can also run on propane or gas.
Not knocking anyone else's kits or setups, just pointing out another option. I don't think this will work on the bigger models.

I'm still waiting on PE piping to come in to test the generator. I did install a new 3/4" full port valve downstream of my meter. Materials purchased from Supply Warehouse. Nice that I could get a 3"x3"x3/4" tee direct.
Deciding on what hose/piping from the 3/4" valve at the meter to the generator was a difficult thing for me. You can get an approved 'above ground' shielded hose for a few hundred dollars or you can get a 'below ground' PE hose for about $25 plus fittings. Since this will always be a temporary set-up, I opted for the cheaper solution. Sure, I'll have to be mindful of how it's routed and put up some physical barriers to ensure no one can accidentally damage it, but it will work.

Me too....and they run like a champ!

Have converted 3 generators successfully with the motor snorkel. A Snapper, Generac, and a Predator. Works great. Can run on NG, Propane, or gasoline. Can have it out and running in 5 minutes and feed thru my welding machine breaker.
Electricity doesn’t fail often enough to justify a stand-by. After converting my first one it was seven years before I needed it! One great advantage is that you don’t have to drain fuel for long term storage!

Hose and connectors came in. Took me a little while to get the fuel to air ratio right, but it was running steady without issue. No more waiting in gas lines for me, hurricanes... Bring it on.
