Project Fat Nikki

Oh well, a year later or more and I'm playing with this again. Put it on yesterday after
going through it again. I smoothed down the spacer gaskets on both sides and I think it
wasn't sealing well and causing vacuum leakage. I was able to get it to idle down around
1100 or so but it wasn't always stable. I wish I could remove the old gaskets on the spacer
and use the new ones that come in the rebuild kit, but those things seem to be glued on
and the space is plastic, so no bueno.

My float bowls are sticking and after shutoff and restart a lot of times it just pours gas
down the intake until I get them to settle down. So I need to pull the top and doctor
the float needles a bit or reuse the old needles and seats which I kept. When the floats
are working the level is on both bowls, so floats are adjusted good.

Also, I have the fuel inlet dead headed into the carb. I'm going to run the lines for the
return and hook up the return line and see if that helps. I think with the inlet dead headed
it is bouncing the float needles and sometimes sticking causing issues as well. Anyway,
it was a lot of fun playing with it. Had to stop when the engine started to overheat
cause I turned off my electric fans as I was trying to conserve battery. DOH!

I will say its very smooth on accel compared to a big 2 barrel like my Dell. I should be able
to just smash the go pedal without thinking once I get it idling good.

What kind of fuel pressure are you running? I've heard the Nikki likes a lot lower fuel pressure than most carburetors at 2 - 3 psi. Definitely following your progress.
