50cc Tao Tao Help  By  dezzymew (Read 9,100 times)

There is also a hose that runs from the bottom of the carburetor. It used to have an adjustable screw in it, but it feel out. What is its purpose?

Thanks for all the help in advance!

Should that drain be plugged or open?

Ill pull plug tonight

Mkay I cleaned the jets and found the screw for the drain and no change. Maybe I didnt cut my cdi enough. Is there a wire I can disconnect vs cutting into the cdi?

I have a carburator for a 150cc scoot. Think thatd give me any benefit?

The only wire you should have cut should have been pink. If it wasn't pink then you just messed something up. Most cdi's don't have rev limiters. Your weights are too heavy. If the engine is stock you need around 5 or 6 gram slider weights. The screw on the bottom of the carb was the drain for the float bowl where all the gas sits before its distributed to the air/fuel mixture. Make sure that wire u cut was pink or else u need to reconnect it or get a new cdi. Get lighter weights. Check you spark plug and see if its dark or light. If its super black its gettin too much gas. It its white its not gettin enough gas. Did you adjust the valves?

The top valve(intake) should be.004mm

The Bottom exhaust should be set to .005mm

If it tapps then try

Intake-.003

Exhaust- .004

Mkay I looked at ebay histroy and the weights are actually 5.5

I swapped the carb for a more adjustable one off a different scoot.

After some tinkering she runs a solid 30-33 on flat.

But once I get going 35 it maintains it for a long time.

Went down a really steep hill and got going 50. Was scary as , this scoot is just not made to go that fast. I need fresh brakes and a tighter suspension before I do that.

My only problem is it has a bit of trouble on the very steep hills. Its been at a friends for all of this and I rode it home and back today and found that for the steep steep hills I had to kick my way up.

I'm thinking I can fix this by swapping for some slider weights.

I have some of the small clutch springs, but not the big one. The small ones are blue if that makes a difference. What spring should I go for?

Im happy with 30-35 but need a little help getting it over the hills.

Now onto body work.

The body is cracked and ruined. I was thinking about ripping it all off and just welding a bracket for the lights. Mine is one of the ones with the huge flat front, will removing this help with speed?

I would think that itd help with aero, but maybe it helps to hide behind it?

I also put a big 35w fog light in a 3x5 off roading light and mounted it where there should have been a headlight. I lost the old headlight :/ Its super bright, but I need to figure out a low beam for when traffic is coming. I have another of the same light so I might mount it below and point it down.

I havent regaped it yet, but its on the list.

Thanks for all the help getting me up and going! ;o ;o ;o ;o ;o ;o ;o ;o
