Hi Roy. I forgot to mention that I did check the position of the slipper pads. They appear to be set correctly. In fact there was very little slack for the tensioner to pick up. I am confident the setup is good. Thanks for the warning. Regards. Jon.
That's good then Jon. It's always best when the slipper pads are close and the tensioner has less slack to take up. Regarding the spring from the tensioner, please keep it safe as it is always something that could be difficult to obtain if anyone needed one. I have the tensioner from Herman and will be using it later but I have another tensioner that has the spring but another part broken so I will be making one good one from the two. ![Smiley](http://www.matrasport.dk/forum/Smileys/default/smiley.gif) That spring you had left over from the carb. is definitely NOT an original part. No Murena ever had anything like that. I suspect someone had fitted it to try to get something that was too stiff, to return. When you say 'adjust' the carb. Jon, do you need to adjust the idle mixture screw? These are buried horizontally in the flange on the Solex 34 CIC. Let me know what the problem is and how you think it needs adjusting and I'll consider it. These are a 'fixed jet ' carb. so generally should need very little adjustment. You only have an idle screw and the idle mixture screw, and it is rare that the idle mixture screw needs adjustment. It only affects the idle setting and the transition to main system anyway. If you have an emission problem it is often something else that is causing the problem. Roy

Hi Roy. Herman send me drawings of the carb that shows that the idle mixture screw can be in two places. Mine is facing the engine. When I first got the car I kept looking on the side where there is a hole matching the other location. My car has always smelled like it got too much gas at idle. At the MOT I was told that the CO in the exhaust was ok, but it was running very rich. I will try to adjust the idle mixture while measuring the exhaust with a lambda probe. Also I need to replace the choke cable. It is very hard to push back, so perhaps that is where the extra spring was used. Will check to make sure choke is fully open with the cable pushed in. Jon.

Jon.
Yesterday I replaced the choke cable. The biggest challenge was removing and reinstalling the clip that holds it in place in the centre console. I also had to bend the clip a little bit in order to hold the cable tight, since the new outer cable sleeve was thinner than the original. After attaching the cable to the choke lever and feeding it through the hole in the bottom of the console, I taped the ends of the old and new cables together with gaffa tape and pulled on the old cable from the engine compartment. After a little bit of tugging and twisting the new cable appeared. Got it fastened to the carburettor and adjusted. It now is smooth and easy to operate. Cranked the engine on the third try and drove a short 10 Km trip to the gas station and cleaned the windows. ![Smiley](http://www.matrasport.dk/forum/Smileys/default/smiley.gif) Pulling in to the carport I had it almost in place when the engine stalled. No power to start it again ![Huh](http://www.matrasport.dk/forum/Smileys/default/huh.gif) so it is sitting there waiting for the next challenge: Finding out why it did not charge. I have a new alternator, but the battery is 5 years old and has not been regularly charged for the past 2 1/2 years. ![Sad](http://www.matrasport.dk/forum/Smileys/default/sad.gif) To top it off, my electronic battery charger quit working. Taking it apart and measuring the components it appears that the thyristor is blown. ![Angry](http://www.matrasport.dk/forum/Smileys/default/angry.gif)

Last summer I had both Murena's the battery bad. I bought 2 for low price (conventional calcium battery 45 aH). ![](https://lh3.googleusercontent.com/-0xwr9q6bRqk/UmqD681JWcI/AAAAAAAAD00/ND2sdLUZkuw/s800/P1060551%2520%2528Medium%2529.JPG) ![](https://lh4.googleusercontent.com/-SBjFGVoW2Ss/UmqD6p9visI/AAAAAAAAD0s/np50ZNbZeNc/s800/P1060550%2520%2528Medium%2529.JPG) They last about 4-5 years because of periods standing still. My 2.2 it last longer because of electric fuelpump. After 2 months standing still it takes 2 seconds to start the car. It saves the battery in the long run. ![](https://lh5.googleusercontent.com/-ijobcezuHYs/UmqD6FRmMII/AAAAAAAAD0k/nh-weBBFCzo/s800/P1060549%2520%2528Medium%2529.JPG) Herman
