Loss of power By churchy (Read 867 times)

It has been long since i have last been on here...I had bent the conrod in my scoot, so have rebuilt the bottom and top end and changed the variator and torque spring.


HOWEVER, now it runs but it isnt running properly, it will build revs, then slowly take off, then go faste, then make a funny noise, and lose revs and slow down, and continues like this..... white smoke from exhaust, any pointers?

If this is a 4 stroke and white smoke it sounds like it is running really RICH that is fuel spraying out to much fuel.

What motor is in the Scoot?
Which Variator Did you get?
What GRAM WEIGHTS did you put in the Variator?
Which Contra Spring did you get(1000, 1500,2000) ?

What sound does the motor make?
A BOGGG sound
A BRAT sound
A POPPING
A BACKFIRE

2 stroke
Minaralli engine
Stage 6 variator
5g weights
1500(came with variator)
Brat sound

Ok, 2 stroke it should smoke that is not a problem.
GOOD you identified the sound
It is running LEAN it needs more fuel, If your carb looks something like this it has a AIR RATIO mixture screw on the AIR FILTER SIDE. Turn that screw about 1/6-1/8 turn CLOCKWISE to cut off some air and richen up the fuel flow.

OK so didnt have any more jets so i poured some oil into the tank to make sure it was rich and problem persists, p.s. can i make it richer/leaner with the a/f screw, or just jets? x
