Forget the specifics (it's been discussed here and the 311s.org forums), but
water flowing through the intake manifold is good.
Did you check the inlet screens in the carb banjo bolts?
Are you running a fuel filter/multiple filters? If not, why not? If yes, are
they fresh and/or showing clean petrol?

Subject: [Roadsters] cooling the intake?
Ok...Dead Betty ROLLS :-)
She runs for like 30\45 minutes...then it leaves me stranded
It feels like vapor lock...like she's struggling to get air or fuel.so I put
an electric fuel pump on.(as if that's a cure).and shortened my tubing to
the carbs.but still.being left stranded 'till she cools down. (darn
redheads)
My operating temp is roughly at 190deg.and I did modify ('cause I'm such the
genius) the water pipes to the intake.actually.I omitted them. As I did the
interior heater box.
Is it possible I'm getting too much heat at the carbs? Is that water flow
thru the intake manifold necessary? And this is indeed my problem?
Any input would be greatly appreciated
Thanks
