The problem,,how would the timing move? Maybe there is so much dirt on the flywheel/stator that it's effecting it???
You did check the reeds?

 

reeds are fine.took out the rollers they were clogged up with dirt no grease at all,they were really worn so was the pully and the cover plate.will i need to replace all of these?cheers pain.............................................. ..........

 

The piece that holds the rollers (sliding face)::Look where the rollers run,if gouged,then replace it.Other than that it should be fine.
Also check the llil plate that contacts the rollers for gouging
The fixed face::This can get awfully abused,but look at how much it is worn with a strait edge.If you know a machinist,you can have him re-face it (13 degrees).
Yes you need rollers [img]i/expressions/face-icon-small-smile.gif[/img]
Check the bearings in the rear clutch while your in there,sand the contact pads "LIGHTLY" [img]i/expressions/face-icon-small-wink.gif[/img]

 

the sliding face and the fixed face are badly gouged.i'll get those and the rollers replaced and let you know how i get on.cheers for your quick response and much needed help,PAIN......................................... ..............

 

Thanks for all the help and this weekend I got the quad fixed. After trying everthing else I swaped the drive faces and it worked like new. It was the drive face with the rollers that was bad. The rollers kept turning sidways. and it only took a year . I see a new posting today with the answer to all the troubles I had. I hope it will help someone else. I packed the rollers with a heaver grease to help keep the rollers in the right spot to see if that would work and it did, I'm hoping this will keep working untill my new parts come in. thanks Doug

 

got the new parts and got it back together.it's alot better on pick up,but there is still a prob on top end real spluttery.i moved the sirclip on the carb needle to the top and it ran quite a bit better,as i was going i disconected the pipe from the airfilter to the clutch casing,and went better still.Carn't really run it with the pipe not on, any more suggs?Running on premix 32:1 RUNNING OUT OF IDEAS HELP.....................................

 

Your problem may be in the carb somewhere,BUT,I'd try taking the flywheel off and sanding it and the stator.This has fixxed this type of problem before.
If thats not it,,then I think the carb "MAY" be bad. A bad carb does what you are expieriencing
I'd like to know what size jets you have in. I looked back and seen that you inspected the reed,so thats not it.[img]i/expressions/face-icon-small-confused.gif[/img]

 

flywheel has been sanded.new 92.5 jet.i noticed on a carb diagram there is a tinyrubber washer under the sirclip on the carb needle this is missing,is this important to the carb?could that make such a differance?cheers lt80,steve........................................ .................................................. ......
