I've got an old Generac 2.5KW generator with a 5HP Briggs and Stratton motor. Over the years, the fuel tanks has rusted and gunked up the carb. I'd rather not rebuild it but switch to propane and/or natural gas instead. Propane would be nice to use this unit at a remote work site while natural gas will let me run it non stop off my house supply as a backup generator.
Does anyone have any experience/advice on doing such a conversion?

They have a couple of options which re-use parts of the old gas carb. But I got thinking that if I machined a block of aluminum to fit, I could save the throttle plate and linkage, fit their kit to it and not have to worry about doing a hack job with RTV sealant on the old carb.
