    lectron tuning
    Posted by mutantboy699 on Sunday, January 18, 2015 12:45 PM

    Had 44mm lectron om my pump gas htg 1000 last year and they worked real wall with 8-1 xl needles, over the summer I swapped them for some 48's and I tried it out with some 8-2xl needles and it wouldn't even take throttle... idles great but any input from 1/4 throttle and up it ran like *** and fell on its face... I was thinking of dropping to a set of 7-1xl and see how it runs... any input?

    Change your power jets.  Needles are for Idle circuit.

    I know the needles control more than just idle on lectron carbs....

    Yes and no.  Needle is for the slow speed.  If you aren't using the adjustable power jets, when you are tuning high speed, if you max out on power jets then you would go to the next size up needle.

    You should call Lectron and ask for their recomendations.

    I would think if you needed 8-1XL for your 44mm lectrons you would need something like 10-1 or -2 or even 11-1 or -2.

    Remember they are taper-bored and flow almost as much air as 52 mm carbs, you need way more fuel

    i called lectron last night and they said that i should be somewhere near right if it idles good and the change in carb size and needle profile shouldnt have a profound effect on my running issue... going to check my ignition and wiring... does anyone have some 10-1xls?

    I think you guys  are over estimating my motor... it's just a pump gas 1000 with trail xcr 800 pipes... 8600 rpm, both lection and fast by gast said it shouldn't be a needle issue... gonna look into my wiring some more.. thanks for the input fellas.

    In my experience when going from 44 s to 48 the needle has to increase about 1-2 steps ex. 8-1 to 9-1 this is for trail engines.

    To what needle lenght do you have them adjusted in the 48mm carbs? Are the Carbs old, I have fund that in some older Lectrons the needle orifice in the carb wears by the needle and takes the shape like a  D ( when taking throttle away and look dow). This causes the needle to draw towards the engine closing the venturi in front of the needle and therefore decreasing the fuel flow.

    So tried it out again today no big changes... slightly better but still falling on its face. If it needed richer needles shouldn't it at least run now? Doesn't ever recover just falls on its face and burbles until I let off. Where's the best place to buy needles? I was gonna try some 9-1's or 10-1's. I think I'm starting to understand the need for more fuel now...

    If its gurgling wouldn't you want to lean it out and not make it richer?? Gurgling to me means rich if were talking about the same thing.

    did you pressure test the needles & seat? did you check the float level?

    Would it change any thing if my old carbs had the long power jet tube and these have the short tubes?

    Or

    You could call Kevin or Dave at Lectron. Very helpful people.  They will take the time for you.

    Lenght of the power jet tubes determine where they start to come on. longer tubes come on around 1/2 - 3/4 throttle shorter tubes come on later. this should not be part of your problem.

    Try adding a touch of choke input. If it reacts better then you need to raise those rods by turning them clockwise into the slides. 

    If it gets worse with a little choke input then lower those needles.

    if you run out of adjustment then go to the next metering rod.

    I guess I'm still confused and maybe its cuz I know nothing about lectrons but why would you want to richen an already gurgling (rich) motor??
