losing power i think

1. How many miles on your motor?

2. The thing on the top of carb is for slack adjustment, not idle control

3. 2nd grove from top is a good place to start with carb adjustment

4. You using synthetic or dino oil?

If you could number your questions it'd help some, kinda hard to decipher a wall of text.

K,

Well, I;d say go back to 32 to1 since it worked better (i run 32to 1 synth oil myself, some guys will say its too much oil i dont) keep clip where it is, adjust the slack only out of the cable via the top of carb and coupler on the throttle. Check the gap on the plug (should be say .028 to .030) also as far as getting up to speed if you just go full throttle is it slow or do you gradually apply throttle? i have to ease the gas to mine as it bogs kinda if you go wot all at once. also when riding turn off your petcock and see if the acceleration goets better for a few seconds as thats the sign of a misadjusted float. hope i helped some, let us know how it works

Some good tips posted above but it sounds like your main problem is your throttle cable adjustment. Remove your air cleaner and look through the carb and make sure your slide can go all the way up and then returns all the way back down. The idle is adjusted with the screw on the side of the carb, back it all the way out and make sure your carbslide can bottom out, then turn in the idle screw 1.5 to 2 turns in, fine tune it by riding and making small adjustments.

Make sure you get the throttle figured out before messing with everything else.

Most likely the reason you feel you are slower switching from 32-1 to 50-1 is the lower oil content gives the gas a lower viscosity and it flows through the carb jets easier making your fuel mixture richer. For what ever reason these engines are shipped with the carb set rich.

When you get your throttle cable linkage issues fixed put the needle clip in the top groove of the needle. This should lean your part throttle mixture. You can tell if the needle is too rich is if the engine misses and four strokes at part throttle flat ground but cleans up and runs better when you open the throttle If you can find one get a smaller main jet to try. thescootershop.com has jets and I believe Sick Bike Parts now have jets. The stock jet will be a 70. That is .7mm. I am running a 68 and it helped. They were out of 66 jets and I think I need one to try. The jets are 5mm Dellorto jets. I am running Opti-2 oil at 100-1 and it seems to work well.

If it runs a new plug wire won't change anything. I small amount at least of mechanical ability is needed to work on a engine. If you have none you are going to have a tough time.
