Zongshen timing chain

It's from Mel Brook's Young Frankenstein.

2 pronged question, which bolts will give me access to bottom of timing chain and 2 turning it over with kick starter has the top of the chain shuddering but not turning, do you think the problem is the chain ?

Your Honda cloned engine is different from my Yamaha cloned engine. However, I suspect you need to remove the flywheel in order to replace the timing chain. To perform this task you will need a flywheel holder, and the appropriate flywheel puller.

If the kick start won't rotate the crankshaft, something is wrong. However, this problem could result from a frozen piston or crankshaft, as well as the timing chain.

The kik starter is moving the piston and flywheel normally, could the chain only have derailed or something, anyway are the flywheel pullers and holder a standard size to order ?

I'm wondering if the tensioner is causing a problem. Perhaps Spud could chime in on that, since he knows the automatic version better than I do.

I was rolling down a hill with the clutch in at the time, the engine was idling and went dead.
I've only had it a month so i wasnt familiar with its normal sound but the middle man that sold it to me said something was noisey.

If you actually need to replace the timing chain, you will need the appropriate flywheel puller which fits that particular Honda engine. You can purchase a generic, flywheel holder on the internet. Here's a link for one such flywheel holder.

If the timing chain had derailed, you would not be able to start your engine.

You can check the automatic, cam chain tensioner (ACCT) in the following manner.

1. Rotate the engine to top dead center (TDC) on the compression stroke, as if you were getting ready to inspect the valve lash.

2. Remove the ACCT, and inspect the plunger spring and mechanism.

3. Retract the plunger, re-install the ACCT, and then release the plunger.

The cam sprocket cover is located at the top, left side of the engine. You can remove the cam sprocket cover to see if the timing chain is under tension. You can also remove and inspect the ACCT as I explained in a previous post.

If the ACCT is defective, and the cam chain is loose, you will need to get another ACCT.

I am not too familiar with your engine. However, a previous post indicated it is a clone of a Honda CB200 engine. You need to verify this is accurate. If accurate, you will need a flywheel puller which fits the Honda CB200.

The cause.
I've got one in my spare motor

So when i press the tension lever with my finger and rotate the engine with the kik starter the timing chain will turn the cam sprocket. Is the timing now out from when the flywheel has tirned and the cam sprocket hasn't ?

[NW1]

Mabey before i replace the ASST i can get tdc on the spare engine and check its cam sprocket markings and repeat them on the engine i'm fixing.
