Follow up to my own post. I think I misinterpreted the function of the throttle. It makes more sense to say it admits more air to the intake, which sucks more gasoline (or propane) in for acceleration. The governor, connected to the throttle also, does the same thing to maintain a constant speed. I do notice a lot of posts dealing with carburetor and gasoline problems. Many of the responses advise rebuilding the carb, using carb cleaner, cleaning jets, even getting a whole new carb, and throwing out stale gas. Also cited are possible seal deterioration from ethanol, and other problems/solutions. I am surprised more people don't try the propane option. By the way, there are several manufacturers of conversion equipment, some of them much cheaper than Altfuel. I only went with them because other websites were almost impenetrable to navigate, and confusing when trying to figure out whether their system would work with my situation.

Dear FPerkins- Unbelievable to read your message. I have almost identical problem. My husband desperately wanted a Weber (silver Genesis)and I wanted the Virco. He claimed that if we bought the Weber he would learn to grill with it, and become a "Grill God". Since I do about 98% of the food prep for our large family (four kids) I was incredulous, but to the Depot we went, and bought his dream grill. That was last month, during which time he has grilled twice, and I have grilled about eleven times. He hasn't touched his grill since mid May, and last week in a fit of frustration I purchased a Virco since the local Costco happened to get three of them in, and experience had shown me they would not be around for long. We now are the proud owners of "his and hers" grills. Ridiculous, and takes up lots of space on our back porch, but alas, compromise is the foundation of a truly good marriage. I agree that once you hotrod the Weber with a cover, stainless grates, rotisserie etc. its obvious what a value the Virco is. Another compelling argument is that the Virco cabinet which houses the propane tank is a much more childproof (and attractive) feature. Still, it is comforting to know I am not the only conflicted multiple grill owner out there in cyberspace!

I also have a natural gas grill that we push around the patio on a 12ft hose. I have been previously told by someone who knows that we couldn't extend the hose. After reading your post I decided to get a more definitive answer. My father-in-law, who was in the gas business for many years, says that adding more hose will reduce the gas flow a small amount. The grill will still work, there are no safety issues, but the BTU output will be reduced somewhat. Perhaps an imperceptible amount depending on the length of the hose. Unlike the pipe that brings the gas to your patio, the NG hose has small corrugations, or ridges, on the inside that slightly restrict the air flow. This results in less gas to the burner. How much less? Dunno.

Thanks for the quick response. After posting my initial message, I called my local gas company and explained what I had done. They told me that I needed to remove the regulator on the grill. They cited the reason as the regulator that is currently on the large Prop. tank will regulate the flow of gas to the grill. They mentioned that if I left the regulator on the grill, that the flow of gas would be less than needed to operate the grill correctly. Does this sound like it is correct to you? Thanks again. -Scopas
