thanks again ,

What's your name? Not that it matters to the carb but it does to me!

You are going to find that dramatically reduced jets will help to further increase your mpg's. But the first thing I would do is increase the gap on your spark plugs. Look under Service Bulletins to find the method for most effective adjustment.

As far as any "adjustments", those should be done with a 5-Gas Analyzer connected to your exhaust.

Does this help?

Barry,

To find out what your carburetor manufacturer recommends for re-jetting is the best practice to follow.

Just tell them you want to reduce the flow rate by at least 20%. Then, contact me with your current jet size and your replacement options and I'll make some recommendations on the sizes.

One key factor is does your carb use metering rods?
