I have a Champion 6500/7200  watts generator 439 cc eng. which i recently modified to run on Natural Gas with the MSK3101 snorkel kit. 
 It sits 12 feet from the gas meter on a 1" line reduced to 3/4" at the on demand regulator.It is equipped with auto start, and has the RSK-AC auto primer and the 2036 uscarb engine meter.
 
 It starts reasonably well,and runs at 3600 RPM at no load

 At 3200 watts of load the RPM's drop to 3350 the voltage and cycles drop to unacceptable levels and i can open the load block all the way and it makes no difference.
 However if i hold the prime button in slightly it will pick up speed. The fuel is obviously available but the snorkel does not seem to generate enough vacuum to pull the regulator diaphragm open far enough to deliver the correct amount of fuel.
 I measured from the carb intake to where the ( gasoline ) jet enters  It measured 1 1/8 inches  the snorkel is  1 1/8 inches long so it sits at the same place as the gasoline jet.
 What am i missing ? This unit should put out 6000 watts with ease.
 Any ideas?

Hi,

   It definitely sounds like you are on the right track. If you PM me your phone number I can have them send you a new snorkel and see if that solves the issue. The snorkels have a lifetime warranty.
