I took it out for a 7-10 mile ride. No stalling, idle was great, at one point I it was so quite I thought it stalled but it was running. I had no issues getting up to 50+ MPH. Only issue is a little lag on the pickup, so I need to mess with mixture screw some more. But, I can do that tomorrow, for now I'm going for another ride!

FANTASTIC!!! And you notice the rear wheel is NOT SPINNING and holding idle beautifully RIDE THE SUCKER.
If it takes throttle leave it alone, give it some revs see how it takes throttle.

Do I really want to go as low as possible with the idle? I was able to get it to idle at 1100 and it was fine, but the wheel doesn't spin till like 2300-2400....should I bump that up when I readjust the mixture ?
EDIT: I guess I could always put the smaller belt back on too? Going for another ride, brb.

Set the IDLE around 1500 or so that is what the 150 motors like to idle around making good even explosions inside , you don't want it idling low even if it will take it. Temp changes will effect it and if idling to low it may die on you.

No the wheel starting to turn around 2300-2400 is PERFECT, you have enough rpms to pull the weight from a standstill.

I really think it was the CDI that was bad and messing with the timing, seeing the rpms jumping all over the place.

your mixture screws about ready to fall out? the tach is showing half the tachs as befroe? what all did you fix on the tach? and you dont want your mixture screw to fall out.
how can you just get a carb, and it be tuned for your bike? it has the same jets in it? did you swap them out? you can check for right pilot jet by doing that deal with the mixture screw and your idle. when you tune it. its justs sort of a check to see if the pilot jet is the right one, and not too lean for the idle. and pilot also sort of controls down low throttle too. youll be around the right area when the mixture screw gives the highest idle, at a fast idle rpm. if you go, out more it drops or in more than it drops. if its before or after 1 1/4 or after 3 1/2 or something, like that turns, then you need to readjust the idle jet.
the tach is showing half the number of rpms as before, but the scooter sounds the same. except for when it happenned to drop, under 3000 it would die.

The mixture screw is only out about 2 turns it takes about 8 turns out before it falls out.

I didn't open the carb, took it out of box and put it right on, I have no idea what size jets it has  All I know is I put 35 miles on the bike today with no issues, so I'm happy! |

i thought i heard you say that. im just saying how to tune the idle and mixture screw off throttle. itll keep you from blowing it, ive said this like, a million times. itll set it right so its not running the wrong jet. if it revs back ok, then your all fine. might want to fine tune. real test is snap the throttle back and if it doesnt quit on you, and has good pull. its good. you can set it on the stand to do this. if it cuts out snapping back there, theres no load and its really lean.

Your scoot sounds awesome man!! As soon as I heard it on the video I knew it was FIXED,,you should plug the old CDI,and coil in just to verify which one was the problem,,if it runs good with your old CDI and coil then you know it was carb,,make sure to do only one at a time...
Awesome!!!
