Jetting spec for one of your F/A

Va Superjet · 06-10-2006, 11:29 PM

Do you guys have a jet spec for adding a flame arrestor to a SeaDoo 720 single carb motor? I found one (new)in a box of stuff I had in the garage and since I have to pull the carb apart to replace the needle and seat i was going to install the F/a too. I need high, pilot and Needle/ seat. Most have told me to go up by two points on the jets and put in a bigger N&S with a lighter spring since the manifold pressure(vaccum) will be a little lower. Any thought?
Thanks,
Brad

Va... should meter with screws... Bn38I series unless you have alot of other things done to it. Power tune it you shouldn't need much more than 1/2 turn over stock.
