This kit includes a mere six O-rings -- two for the needle jets, two
for the adjustment screws, and two for the bowl drain screws. The price
is $7.50 shipped. If you pay via Paypal, it'll be $8.03.
For convenience, I also offer the '450 Combo', which includes the carb
kit, the intake O-rings (40mm) and a set of stainless intake boot
fasteners
(20mm) for $14.20 shipped. Again, with Paypal, it'll be
$14.93.
