I bought a 50cc kit from this Chinese co. which includes a muffler and pull start.

My problem is I have a very rudimentary knowledge of mechanics and an even more rudimentary knowledge of interpreting Chinese English into English English. eg Having worked out I needed to remove a cover to fit the chain I then discovered the chain was too big to fit on the sprocket, so I e-mailed the question and received the reply. 'Hi friend. Remove the cover.' I solved it by breaking the chain on the master link.

There was no advice on how to fit the throttle cable and nor the clutch cable. What it fits to and how it operates. So I asked them. This time the reply was. 'Hi friend. We can replace cable for 25 USD.' (I'm English BTW). This and a few other problems not covered by their scant instructions has left me in a bit of a quandry.

Is there anyone on here who has successfully fitted one of these beasts and if so can I pick your brains please?

Thank you in anticipation.

Ant.

If you have problem just ask specific question and someone will come riding up on a white horse to save the day. At least it works that way most of the time.

jasonh kindly directed me to a wonderful site that gives a blow by blow account of how to fit, but I've run up against another seemingly unfathomable problem.

'Reach into the space below the clutch lever and
spin the small chain sprocket with your finger.'

It doesn't spin. This appears to be because it's in gear and I don't know how to get it out of gear. I've fitted the cable and springs correctly and the two controlling levers I have operate ( one takes it from 1 to 3 and the smaller one takes it back to one again) but this sprocket seems to be constantly engaged.

Any suggestions?

Anthony, If You Have The Kit That I Beleive You Have, There Is Only I Gear (speed) There Is No Neutral. Only Clutch Engaged Or Disengaged. The Little Arm Above The Motor Sprocket Is The Clutch Release Arm. The Clutch Is On The Other Side Of Motor, Under The Cover. A Rod Runs Thru A Hollow Shaft To The Other Side. Take Cover Of Booth Sides And Study It. You Will Have To Learn How To Adjust Clutch. Be Careful So You Don`t Break Clutch Arm. Its Basic Clutch, Once You Understand It. When You Take Cover Off Rite Side, You Will See Small Gear On Motor Crankshaft The Drives The Big Gear On Clutch Housing. The Clutch Drives The Chain Gear. Study It And Read The Pertinate Posts. It Will All Fall Into Place For You. Take Your Time And Enjoy Your Build. They Are Great Little Motors, They Love Attention, And You Can Not Holler At Them. Ha Ha. Ron
