Gidday Guys,

As the title suggests, Im putting a 28 motor in my 21 with my 21 carbs. Am I safe to leave the jetting as it was when the carbs were on the 21 motor, or would I be wise to change it? I see from the specs pages, the 2 models have the same compression ratios. Maybe there's more to it than that.

My intention is to put it on the dyno to get it sorted after I get it going OK. Am I right to use what I have for now?

If you have any other comments/advice regarding this swap, I'd be keen to hear them!

Thanks
Richard
