Solex
These are copies of pages from a Porsche Workshop Manual Supplement for Solex carburetors. This
information applies to all Porsches using the Solex 40PII-4 carburetor. If you don't have a copy of the
manual you will find this information helpful when installing, tuning, or trouble-shooting your carburetors.
There are a number of other issues to consider before having your carburetors restored:
Do you have a fuel filter? The "stuff" from the bottom of your old gas tank may be clogging passageways
or jets, resulting in intermittent performance. And that will continue with your restored carbs!
Check your fuel pump pressure. This is particularly important with the Zeniths
VERY IMPORTANT, check your distributor! Timing, most importantly, consistency of timing, to making
sure your engine is performing correctly. A petronix addition to your distributor may help if you have a 12
volt system, not with a six volt.
linkage connected properly, from the fuel pedal to the carburetor.
Valves, rockers, pistons, all functioning well
Click on the specific page for an enlargement. You can always print the page out if you need to.
Do you have the right carburetor set up for your engine? check these specifications to find out what is
correct for your original engine.
"Exploded" parts diagrams of the carburetors are available here, so you can see what parts may, or may
not, be missing, need to be replaced, or are broken. Those diagrams will also help you in ordering parts if
you want to repair or rebuild your carburetors yourself. Most of all, these diagrams are essential in making
sure all parts are re-installed in the correct order.
Remember you can call or e-mail 356 Carburetor Rescue if more help is needed.
