I'm having a problem with the auto/clutch engaging while ticking over it keeps tryin to engage i try to keep tick over as low as poss but if i go to low it dies

i've had this engine about 18 months and is still a good engine to say i give it sum stick pulling my little trailer.

i've not used it for a few weeks and now it's playin up it ticks over ok but the clutch keeps juddering by that i mean tryin to engage while waiting at trafic lights and ands up cutting out just as the lights change to green it's so embarrasing.

any ideas why guy's ??

Lower the idle speed, or raise the clutch engagment speed with slightly stronger clutch springs.

as i said idle speed is as low as i can get it, so as you suggested i'll have a look at springs as they must have worn as it's about 2 yrs old now so , Thanks

Clutch bushing needs lube

Well i've opened up the clutch housing and i think i've found the problem the clutch plate is badly worn and the pins too which has caused to badly wear one of the clutch plates too so looks like i'll be needing a new clutch assy ?

see attached pics

anybody any idea where i can get these parts from ?

i dont think this is the same clutch assy as mine ? but i have sent bicylce-engines an email with a pic of mine to compare with the one on there web site but i think the one they are showing is for a skyhawk box. thanks.

I have attached a side view pic of my g/box. + a pic of my C/clutch & a pic of bicycles C/clutch. Please note the difference

There will be a little drag when idling at a stop. That's not a problem. Mine does it too. If it does not cause the bike to take off or kill the engine, it's fine.
