Let us know if it is a good product

So is the lamp doing what it's supposed to? What's the timing on your motor now?

It hasn't arrived yet, only yesterday it was shipped...
I also ordered the anti-flood membrane for the carb, it arrives in 10 days, from peugeot (10EUR)

Now I am searching for a clutch kit, it seams that it is 145EUR here (valeo), clutch disc, pressure plate and bearing. From what I understand the flywheel isn't necessary to change right? (usually), because it would be another 70EUR...

BTW: gas consumption seems to be constant at 13-13.2 l/100km now, 100% city

So if it'a any comfort, my carb is so messed up it uses 13.2l of gasoline on 100km in the city. I stress it's normal driving, no shifting beyond 3500rpm. But that is a consequence of my driving only on LPG. On LPG i do have a heavy foot and it comes up to 10l/100km but that is really sports driving. As far sports as the 1.3 allows.

The flywheel doesn't need changing if the surface to the pressure plate is not damaged. If it has grooves then it needs changing. A piece of advice. If the grooves are minor and the flywheel is not bent in any way, then using rough sand paper to give it more friction does the trick. the clutch gas a far better grip then and it does not harm the clutch disk.

In order to lower your consumption you have to respect the 1500-2500 rule (change up at 2500 and change down at 1500). If you change up or down at higher or lower rpm, you will automatically get a higher petrol consumption.

[missa91]

Yeah, but my engine simply hasn't got the power to handle a hill that's 8% steep. So for the entire hill I've got to put it in 4th and rev it around 4000rpm. any less, there is simply not enough power. And there are a lot of hills in my region.

[alargeau]

Oh but you didn't tell us that! That changes everything.

[missa91]

What does it change? I mean here half of the country is flat and the second half is in mountains. I live in a region called "Sumadia" which means hills of forests. And every way I turn I have to overcome a lot of hills. When I travel alone the situation is best, but when there are 4 people in the car, then I think I'm driving a 49ccm scooter.

It's the same with mine, it is not powerfull

It changes consumption of course.
I have the same feeling when driving in mountains, sometimes I think the accelerator cable is broken.

today the timing light arrived.

first i set the idle speed because it wasn't stable at all. I couldn't find the idle mixture screw, only the idle speed screw. So i turned it and fortunatly the mixture screw wasn't in need of change. Now the idle stays at 750 and oscilates only very little above and below this line.

With the timing light i saw that the avance was at about 5 degrees. From the 405 book i saw that it should be 7 for unleaded 95, so i set it like that (youtube video).

The I took a drive through traffic to check where the oil temperature would reach (photo).

I think it has a little more power now, but i am not sure, as for the oil temp, it is still to high I think...

What do you think?

[thefunkyboy]

Do you try it in the same condition as before? It seems to accelerate better?

It does accelerate better, but the clutch slips so I can't really be sure. And the oil temp problem still exists.

*Note: If unleaded fuel is used in the following engines, the ignition timing must be retarded by 3° - check with your Peugeot dealer.
a) TU3 (K1A)
b) TU3A (K1G)
c) XU92C (D2D)
d) XU9J2 (D6A)
e) XU9J4 (D6C)
f) XU52C (B2A)

But I am not sure about those 7 degrees, is that setting correct? Did you see the video?

BTW: I use EFIX95 gas from rompetrol with cleaning additives, benzol I think. The gas comes with it. It's 5% ethanol, E10 isn't available here yet.

I would do the following: replace the temperature sender for the oil, change the oil, oil filter and maybe remove the oil pan and see if there is any dirt, so it can be removed. And I personally think that you have a quality oil, so, such a temperature is no problem for it.
