Woo Hoo! I just did the 40 mile round trip mileage check again today.
Last week I asked my neighbor to lend me his skill and knowledge to help do a tuneup and set the carb. He came over and brought a vacuum guage, timing light and a sheet of facts and figures. He showed me how to do all the tuning and adjustments to get everything tweaked out to the optimum.
Well today I did the 40 mile thing and I'm proud to say I achieved almost a 45% increase in fuel mileage!!!!
Instead of 6mpg I'm now getting 11!
