help - gicleur - 1776cc - solex 40 kadron

[rafaelzampieri]

good afternoon, I would like the help on which gicleur (jets) to use.
 I'm putting together a pair of solex 40 eis kadron and I needed help with the gicleur/jets to use. My engine is a 1776cc, with w110, Heads cb 044, 40x35,5, with rocker 1.25, 8 per 1 rate, petrol, with exhaust 1 5/8.
Which gicleur/jets measurement should I use as a main and slow injector, floa, needle?
in addition, some modification do you advise?
Thanks Very much

I think I ran 130/60 main and idle. I had Mr. Kadron re-bush the throttle bushings with sealed bearings and installed ball needle valves from Gene Berg. The dual port manifolds were ported into the heads and the stock valve heads were ported by Mick Wooten.
A huge improvement in idle smoothness came when we switched the manifold balance pipe to a larger diameter, similar to the one used on a carbed Type 4 powered bus rather than the 7mm fuel injection hose supplied in most kadron kits.

A huge improvement in idle smoothness came when we switched the manifold balance pipe to a larger diameter,.....

The way to get a Kadron engine to idle on all 4 cylinders is to remove the wall between the runners of the manifold almost all the way to the head.
All of the available manifolds were designed by people who know individual runner carburation and don't understand the need for a plenum.

Good idea Bruce. The Engle 110 is not helping the idle either. 

[Bruce]

When you switched to a larger balance pipe, you increased the plenum.  By cutting away the wall in the manifold, you can toss the silly balance hose.

If thats true Bruce, then why would VW use the tube on the T4 carbed bus engine? Manifolds too short? They could have saved a few parts without the tube.

They had no height to play with.  They couldn't make a plenum big enough if they tried.

Look at a V8 with a single 4bbl carb on a manifold with a giant toilet bowl under it.  Volume is needed in the plenum.

Interesting. That would be good to try OP.
