Quote: The 4160 series 600 on it now seems to work pretty well. I was just thinking of going for one a little bigger.
You will be impressed up-grating to the 3310 over the 600 1850 on that 383, not that the 600 won't work, but you'll get power all around with the 750. Obviously you must have noticed an improvement with the larger Eddy carb despite its issues, thats why your wanting more CFM. If you go on e-bay, you can find a bunch of good used 3310 750s for cheap, I got mine for 113.00 to my door, & it was hardly used, its alot cheaper going this way then buying new.
