Title: cant figure this out
Post by: udontknowme on September 24, 2013, 01:49:38 AM
anybody got a idea whats making the stutter sound ?  everything i tried and  cant get it to go away. not even sure if its the needle or pj causing it. running out of ideas. almost thinking to throw a ton of fuel at the needle and pj then see what happens.

Never hurts to add fuel when trying to solve a fuel issue.

There is only the needle and power jets to adjust usually the needle will solve most part throttle issues so start with it.

Make half turns on the needle unless you are really off then you can go full turns, just always remember the flat side of the needle faces the motor.

There is only one way to learn and that is to keep making adjustments until it gets better or worse.

sounds like to much fuel to me.I would look at the plug to confirm that

it may be over fueled.  what i dont understand though is why no smoke ?  after that vid i checked the plug but i dont know if it was accurate because i rode it back to my truck. at any rate it wasnt burning any plating off but that hill is short so maybe there wasnt enough time to build heat. if i turn the knobs enough eventually ill figure it out. then ill start in with the timing which im alittle confused about aswell. one article i read you should put the timing as much advanced as possible and still be safe then retard it until it meshes well with the carb tune. but how do i do that until i get the stuttering problem fixed. i think theres several ways to go about it and everyone finds the method that works best for them. im sure its not as difficult as it seems. im new to alky and this is my first lectron so im battling two unfamiliarities at the same time
