Thank you, I knew that. It’s a 650 cm model number 1805. It originally came on the car when I bought. The stock jetting on that carb was 98/95’s Which is very rich. I since installed 92/89’s. It’s pulling a lot harder now. But, I’m pretty sure I can downsize both one more time. I was just wondering what the generalization is. At one time this carb had 104/101’s. I mentioned what it has 92/85’s now. Can you believe the gas mileage never changed a bit at 11mpg. That’s a huge jump in jetting. Average 9-12 mpg regardless of any conditions. Everything is tuned properly and new. It runs great. But, she’s a drinker. That’s for damn sure.
