Re: Fuel pump on 85 GW
Be sure to carefully check and set your float level and be careful with the
needle valve.

Re: Fuel pump on 85 GW
Hi Group
Finished up the carb rebuild. It really needed some
attention it seems. Lots of leaky gaskets. Basically
a clean job. Almost fun! No more leaks so the gas stays
in the float bowl and it starts up cold fine again.
One issue with the carb kit. The carburetor seems to have two gaskets
under it. A smaller one right under it and a larger one
between that and the manifold. The larger one looks like
its main job is a spacer on my engine that makes the carb sit higher off the
engine. The new kit contained the proper smaller gasket but a much thinner
spacer gasket. Since the spacer gasket
on the engine looked in perfect condition I reused that
one. The new gasket would have changed the carb height. That didn't sound
right. Running like new now.

Re: Fuel pump on 85 GW
Hi Group
Finished up the carb rebuild. It really needed some
attention it seems. Lots of leaky gaskets. Basically
a clean job. Almost fun! No more leaks so the gas stays
in the float bowl and it starts up cold fine again.
One issue with the carb kit. The carburetor seems to have two gaskets
under it. A smaller one right under it and a larger one
between that and the manifold. The larger one looks like
its main job is a spacer on my engine that makes the carb sit higher off the
engine. The new kit contained the proper smaller gasket but a much thinner
spacer gasket. Since the spacer gasket
on the engine looked in perfect condition I reused that
one. The new gasket would have changed the carb height. That didn't sound
right. Running like new now.

Finished up the carb rebuild. It really needed some
attention it seems. Lots of leaky gaskets. Basically
a clean job. Almost fun! No more leaks so the gas stays
in the float bowl and it starts up cold fine again.
One issue with the carb kit. The carburetor seems to have two gaskets
under it. A smaller one right under it and a larger one
between that and the manifold. The larger one looks like
its main job is a spacer on my engine that makes the carb sit higher off the
engine. The new kit contained the proper smaller gasket but a much thinner
spacer gasket. Since the spacer gasket
on the engine looked in perfect condition I reused that
one. The new gasket would have changed the carb height. That didn't sound
right. Running like new now.

Re: Fuel pump on 85 GW
Fred,
Back in my drag racing days we tried all sorts of 'tricks' to get an edge in
performance.
One of those was spacers between the carburetor and manifold for two reasons
heat insulation and addition space for vaporization.
One thing is certain.... an awful lot of problems were caused by improperly
set floats and improperly balanced venturi.
It surprises me sometimes that guys with the older Jeeps live with their
carburetor problems....sometimes they are stuck because they live in a
socialist run state (like the kommunist koalition of kinky kooks and
knotheads of kalifornia) that go spastic if you want to make a change to
make your vehicle run better and pollute less..
Rebuilding carburetors used to be something that was commonplace and done
regularly but I guess that all the people who knew how are probably
retirement age now...

Back in my drag racing days we tried all sorts of 'tricks' to get an edge in
performance.
One of those was spacers between the carburetor and manifold for two reasons
heat insulation and addition space for vaporization.
One thing is certain.... an awful lot of problems were caused by improperly
set floats and improperly balanced venturi.
It surprises me sometimes that guys with the older Jeeps live with their
carburetor problems....sometimes they are stuck because they live in a
socialist run state (like the kommunist koalition of kinky kooks and
knotheads of kalifornia) that go spastic if you want to make a change to
make your vehicle run better and pollute less..
Rebuilding carburetors used to be something that was commonplace and done
regularly but I guess that all the people who knew how are probably
retirement age now...

Re: Fuel pump on 85 GW
Fred,
Back in my drag racing days we tried all sorts of 'tricks' to get an edge in
performance.
One of those was spacers between the carburetor and manifold for two reasons
heat insulation and addition space for vaporization.
One thing is certain.... an awful lot of problems were caused by improperly
set floats and improperly balanced venturi.
It surprises me sometimes that guys with the older Jeeps live with their
carburetor problems....sometimes they are stuck because they live in a
socialist run state (like the kommunist koalition of kinky kooks and
knotheads of kalifornia) that go spastic if you want to make a change to
make your vehicle run better and pollute less..
Rebuilding carburetors used to be something that was commonplace and done
regularly but I guess that all the people who knew how are probably
retirement age now...

Back in my drag racing days we tried all sorts of 'tricks' to get an edge in
performance.
One of those was spacers between the carburetor and manifold for two reasons
heat insulation and addition space for vaporization.
One thing is certain.... an awful lot of problems were caused by improperly
set floats and improperly balanced venturi.
It surprises me sometimes that guys with the older Jeeps live with their
carburetor problems....sometimes they are stuck because they live in a
socialist run state (like the kommunist koalition of kinky kooks and
knotheads of kalifornia) that go spastic if you want to make a change to
make your vehicle run better and pollute less..
Rebuilding carburetors used to be something that was commonplace and done
regularly but I guess that all the people who knew how are probably
retirement age now...
