Just a quick question. I am in the middle of a rebuild and boring 20 over on the cylinders. Do I need to worry about re-jetting the carbs?

On this model yes!!! Its the big bore and sleeves are already thin stock..jump at least .002 bigger

Thank you for the reply. Do you have any idea where to buy them from? I have been looking and can’t seem to find any but stock.

What is the stock part # here.

 

[Wayne65]

0320661 is the part number I found.

 

[racerone]

320661 is a 61C----You would want a 63C and that part # is 321559
