Vrally 4L

Please Help!
I have renault 4 GTL 1988, 1108ccm engine
I put Solex 32DIS from renault 5 956ccm
a have problem with top speed, acceleration is good, but top speed only 120km/h
Distributor on car is Ducellier with curve R298D61
also have Femsa with curve R244D61
and Magneti Marelli with curve R335D83.
On full throttle I loose power with Ducellier.
Which is the best? Or I should put original Sev Marshall form 956ccm engine?
Contacts are on 0.42mm, vacuum is perfect and new from Dacia 1300
Thanks!

Bon mon anglais est naze !

Fesma distributor is the worst distributor.

I prefer R335D83 curve for 1108cc

Thank you very much. I use Google translate, so you can answer on French )=

I put MagnetiMarelli r335D83 and car was lazy, then bought Ducellier r244d61 (with only 50000km) and now everything is good

R244D61
centrifugal:
0@1200-1400
14-18@3000
32-36@5000
vacuum:
105-474mBar
20-24 max

R335D83
centrifugal:
0@1300
11-15@2500
26-30@5000
vacuum:
93-266mBar
12-16 max

That was a problem, too late ignition with R335D83
