Hi all again,
i thought it would be usefull to tell you a story about the distributor replacement in a Fiat 1108 ie engine, since i replaced it before 1 month and had some strange problems.
For the last 3-4 years i knew that the distributor centrifugal weight springs had problems and the ignition advance wasn't correct in all rev range. I tried to change only the springs and i thought it was fixed. But... the problems appeared again
So, i decided to replace the whole distributor with a new one. After searching the market they told me that there is one for the 1.1 ie engine. It was a Marelli ditributor with cost about 130 Euros. I bought it and the replacement was easy with instructions from Haynes manual. Then i went to a local fiat garage and asked them to set the correct ignition advance because i don't have an ignition strobo instrument.
But, they couldn't set the correct advance because if they set it at the correct advance degrees (13-16 BTDC) the engine idle revs were at 1000 - 1200 rpms instead 800-900 that is the correct idle revs. So they decided to set the advance at lower degrees and the car wasn't going well as in the past.
I started searching and i found that the distributor model was Marelli SE101AB but the model that the 1.1ie engine uses is the Marelli SE101C. I asked about this model and they told me that Marelli produces now only SE101AB now and SE101C has stopped. I also found that that the SE101AB is for the 1000cc engine.
I was lucky i had a fiat mechanic friend and he told me to keep the SE101AB distributor and change the vacuum advance diaphragm with one for the 1108 engine because it has a longer plastic driver, then the one that came with the SE101AB distributor, and a little harder diaphragm.
I did it and it was possible to set the correct ignition advance with no problems.
PS: I hope you understand my english writing
