SU HIF Carbs 120-130

I sure hope they are HIF6s. That is what they look like.

They are good carbs but the temp comp may be a little overrated. You may or
may not be able to tell the difference in extreme cold weather. If properly
adjusted you probably would not have to use the choke for as long after
startup.

Be SURE you get the right heat shields for them (individual small ones that
go behind each carb float bowl). The double one as used with HS6 carbs is
ineffective for these. You will probably need a set of new air seals for
the throttle shafts, cute little rubber bellows things, as well as top dampers.

You might want to convert to the single plastic airbox with rectangular
air filter too. You'll probably have to drill some holes in it for bolts
and vents and make some gaskets for it. I used green reinforced file folder
material and it worked OK. Be SURE the mounting bolts are in there to stay.
I had to pull a head and a valve to get some of them out once.

I was once sold on Grose Jets. I'm back to regular needles and seats.
Long story.
