Well I just did something that I have been holding off 'cause I knew it was going to be bad. I did the math for milage ... 3 mpg ... 3 good God I knew it was bad but 3 - jumpin' jehosifats ... It's like there's no jets ... a 1/4" hole would be about right ... oh and by the way this is the second carb as the other one was shot inside. I think I may replace the carb with a garden hose ...
