The
Lectron Metering Rod
Thank you for buying a LectronŽ Carburetor. We at Lectron believe
it is the finest carburetor that money can buy. With a basic understanding of
the Lectron system and with these instructions, you will be able to tune your
carburetor in a very short time.
Understand that Lectron uses a single fuel metering device. This one
simple device takes the place of a pilot jet, intermediate circuit, and main
jet found in a conventional carburetor. This one metering rod is equivalent to
approximately 10 main jets in a conventional carburetor.
To understand this fuel metering rod, see this picture below:
Dimension (B) will vary according to the number of the metering rod. A
higher number would mean the dimension would be smaller, making the metering
rod richer. Just as a conventional carburetor, a smaller number jet is leaner
than a larger number jet.
Dimension (C) these are the adjusting threads, which will remain the
same on all metering rods.
Basically, you dial in the low speed by turning the metering rod.
Turning the rod up, or into the slide would make the low end speed richer. By
turning the needle out of the slide, this would make the low speed leaner.
(SEE METERING ROD ADJUSTMENT CHART).
When the engine will start, idle and take throttle, you are ready to
make a top speed plug check, to assure proper high speed mixture.
If the low end is satisfactory but the top end is too lean, change to a
richer metering rod, setting the richer metering rod at the same distance as
the previous one. If the top end is to rich, go to a leaner needle, setting it
at the same distance.
Be sure that your engine is in good condition, the ignition timing is
set correctly, the valves are adjusted and the compression is up. Make sure
there are no obstructions in the exhaust system. If all these things are
correct, the carburetor will be easier to tune.
NOTE: BE SURE THE AIR CLEANER IS BIG ENOUGH TO SUPPLY THE AIR REQUIRED.
