Peugeot Elyseo 125 Scooter Repair: Troubleshooting Timing, Ignition, & Camshaft Position Issues

Hello, at the outset, I immediately say that I am new to this forum, and I may have a problem with punctuation, but to the point.

Not long ago, a friend brought me a peugeot elyseo 125 scooter for repair,
apparently something shot in it or something while driving and from that moment the scooter would like to start but could not, I started with checking the spark, the fuel is charged, I thought that maybe the ignition changed and here the stairs began,
I found a service shop on the net for this model, I did everything right, i.e. set the magneto in the position it should be, then the camshaft position, I put on the chain, tightened the screw and put the tensioner on, but then you have to do an activity that I do not understand, see the attachment to this service.

There is a picture on page 21 and it is described in English what to do, if someone had contact with these motors, please help.

It is a valve lash adjustment.
You turn the engine clockwise so that the cam on the shaft is on the other side of the "pusher".
You measure the gap with a feeler gauge and adjust with a screw.
Suction valve 0.10mm
Exhaust valve 0.25mm
The correctness of the adjustment is checked by the inability to insert feeler gauge plates thicker by 0.05 mm.

So after setting the timings, I turn the motor clockwise so that the cam is at the back of the pusher?
The photo shows the suction valve or is it just about setting this valve?

You set up the engine (shaft) for the intake and exhaust valves separately. the job for everyone is the same, but different shaft positions (cam on the other side of the follower).

So I do this: after setting the magnet and shaft, I turn the engine to the right and set the intake valve after setting the suction, turn the shaft again so that the cam is at the back and set the exhaust valve, is this to be done?

Exactly.

Thank you for your help, tomorrow morning I will try to set it up and let you know if it helped.

What bullshit ... you never set valves like that. You set the exhaust and intake valves simultaneously, the magnet wheel to "T", the camshaft with the cams in the opposite direction of the tappets and that's it. Such adjustment will ensure correct setting of the clearances when the piston and valves are at their highest pressure position during normal engine operation ...

Gentlemen, in my opinion, first I set the timing "book", then valve clearances.
In addition, I notice that the valve clearances recommended by my colleague above are too large in my opinion, it is better to stick to the manufacturer's data. Perhaps 0.10 - suction and 0.15 mm - exhaust.

The valve lash can be adjusted in two positions of the camshaft. At crankshaft T position, or at the cam position opposite the follower In the case of this Peugeot, according to After service, the matter is not entirely clear, but minor differences in regulation will not affect the engine operation here.
Worse in the case of Honda, because in the case of multi-cylinder engines within one motorcycle model, but in another year of production, there may be differences in the method of making adjustments. For example, for one position of the R4 engine shaft, the valves in two cylinders are set, after turning by 90 ° in the other two ... When setting the standard method, it turns out that there is a difference of up to 5 hundredth of a millimeter in relation to the recommended one.

Hello, I forgot to write back if the regulation helped or not, I set everything as it is in the service center and the valves, as my friend explained to me, but nothing of the scooter when started by the starter, as if it would like to be caught, but that's where it ends, generally with this scooter it is worse than I thought when turning the starter, the engine locks up and you have to reverse it, in addition, something rubs on the crankshaft. I wanted to disassemble it, but this engine is not worth overhauling, the cost of gaskets for the cylinder and heads is PLN 100, let alone the rest, you write that you need to set the timing through the marks on the magnet, but there is no reference point on the crankcase as it is in the Chinese.
