Just grease the ball joint once again after 300-500 kms. It should be free by then.

I bought a grease gun hoping that I can do the greasing myself, but its a messy affair. I used it on Bajaj Classic SLs front suspension and managed to break the grease nipple head inside the greasing socket. And the places that do do greasing still, the grease quality is suspect - feels like maida paste

DID- 26-30 xxxxxx is all what I could figure out. 26 mm - dia of the primary side air passage, 30 is the dia of secondary side air passage on the throttle body. I am not able to locate any number for the carburetor body piece. Probably they are common across Zen, Esteem and 118NE. The Maruti carburetor is numbered DID - 24-30, meaning dia of primary side is 24mm. The jet sizes are 92.5 and 155 for Zen. However these values need to be calibrated while using the same carburetor on a Padmini. My 118NE seems to run lean with a zen carburetor with the above jet sizes.

That would be Lucas 700 with Right Hand Drive written on the glass lens. The original bulbs will be spherical double filament 45/40W P45T.

Many thanks to the Fiat Guru for all his valuable inputs in my endeavour towards developing an adaptor for installing a Mikuni carburetor in a Premier Padmini.
With the preparation done during my previous vacation, I was left with only the installation job. The adapter, carburetor and accelerator pedal with cable were installed in no time with my cousin giving a helping hand.

Hoping to install a crank case ventilation system I picked with the push rod inspection cover from a super select engine lying with my mechanic. Swapping it was more time consuming than I had expected. I had to remove the distributor and the compressor bracket. Again, setting the distributor with no timing light was yet another zig saw puzzle.
Went under the car and installed the fuel return line.

With 4 days of work inside the bonnet, I totally relished the fruit of success. For now all crank case ventilation ports are plugged. Installed new spark plugs, new gasket for rocker arm cover and side door.

The starting, launching and cruising was super smooth. Loved every bit of driving with this mikuni system.

To do, during next vacation.
1. Relocate the fuel pump inside the spare wheel well.
2. Use metal hoses and reduce the length of rubber hoses used for fuel lines.

That's all folks.

Dear ilangop
Why are the additional holes drilled in the air filter of your car.
I think it's not right to plug the crankcase ventilation system , rather you could have left it open for the vapours to escape.

Hi Arun,

The holes exist in all 118NE air filter boxes. Part of Nissan filter box design. No idea why they are present.

The Premier Padmini side door does not have any holes for the gases to escape. Only the Italian Fiat 1100 had them. So I believe there is not harm in shutting the holes for now.I got this cover from the scrapyard and swapped it here in place of the Padmini side door cover. When I find time, I ll install a PCV and route the hot gases back to the intake manifold.

While browsing through some Australian Millecento's, I came across these two pics that show some additional parts (circled in yellow).
Fiat Guru's: can you throw some light on what are these parts?

The bottom circle on the first picture is the bottle coil that feeds the distributor.

Second one I think is the valve to control coolant flow for a heater core in the cabin. There is a coolant line coming out from that valve and going into the cabin. Looks like this model had hot air blower in the cabin.

A comprehensive equipment list with differentiation between variants. Unfortunately not dated.
