12.9 13.0 n/a
12.8 better to be safe then sorry
you can tune they spray be air/fuel and your plugs to see how far you can go with the tune
does not need to be a pro to tune it
carbs need tunning
That 3310 isnt fully open until 5600
Yeah I've tuned the spray to make sure the fuel ring is in the right place and there is no black specks on the porcelain either. It seems to be at just the right spot for the spray at least. I'm gonna work on the carb this season with Inertia to try and dial it in a bit better but up till.now I've been trying to get the idle afr up as it's pretty low. Need to mess with the fuel transfer slots or hopefully just restrict the air bleeds a tiny bit.
