Lectron carbs

Recommended Posts

Do you know if they are set up for gas or alky. I'm interested in a set of gas

All you have to do is change the needle to go from gas to alky. Sometimes people drill out the "main" orifice on alky but I think you can still get gas to work with a needle change. I've never tried it.

 

Those don't appear to be the typical Packard PE1 needles but Lectron makes their own alky needle too. I'm not sure what it looks like. If OP can take a better pic of the needle or read the numbers in it that would answer it.

These were said to me that came off a bike with regular Gas not Alki. I will post pics of the needles in a few minutes.

And to add to my comment (this should make Claude happy)

 

The 4 is on a scale of 0-10. 0 being leanest, 10 being richest on the TOP END jetting. The 3 is on a scale of 1-4, 1 being the leanest, and 4 being the richest on the MID RANGE jetting. The XL just indicates that it's a later model needle that will work in carbs from 34-44 or something along those lines, I forget. The early ones just had numbers. I have seen 2 other variants of lectron needles (metering rods). One was PE (Packard Ent.) And the other FBG (Fast By Gast). The PE have a VERY different look, the FBG however wasn't so different to the eye, but tuned quite different. They both have their own tapers etc. With the PJ you do not need/want a super rich WOT number as that eliminates the need to use the PJ for the fine tune dial in.
