Query for fiat experts -

(A) -

Had attempted to tune the vehicle yesterday using a timing light, dwell/tachometer.

Gap between the CB points was too large, after reducing it, the dwell angle achieved was 58 degrees.

Gap between electrodes on spark plug was set to 0.7 mm using a feeler gauge.

Idling RPM was set to 720 and ignition timing 10 degrees BTDC @idling.

The car drives much better now but when I checked the spark plugs later, there was a substantial amount of soot deposits indicating that the engine is running rich.

What could be the problem?

The air screw has already been opened up as much as possible (a) to allow steady idling (b) max engine rpm was attained after which it tapered off when rotated in either direction

I am using a 102 main jet.

I suspect the float setup to be problematic, any other thoughts?
Despite cleaning the distributor and and another tune-up, the problem still remains. Will try using a 97.5 main jet.

Probably oversize bushings are called for - any other suggestions?
Oversize bushings were installed. All noises are now gone

97.5 main jet was procured from Jay Motors @ Nanapeth and was duly installed. Hopefully, this will ensure correct metering of fuel.

Damaged exhaust pipe has been repaired. Am on the lookout for a new one.

Car drives like rubbish using a 97.5 main jet. Had taken it for a spin last night and it was sputtering all the while.
It felt downright horrible

Am experimenting with a 100 jet. Performance has improved somewhat but still not in the same league as a 102.5.

A slightly rich running engine was probably not such a bad thing after all....

Updates -

102.5 main jet is back in use. Have added the missing breather pipe to the intake manifold (which had been blocked using a bolt earlier). The car drives/feels much better now.

Thanks a ton Mr. Dhabbar sir

Have replaced the muffler which had been patched up earlier as it was badly corroded. The familiar growl is back.

A few more things on my to do list -

(a) replace self starter bendix assy
(b) doors / glass winders need adjustment
(c) steering gearbox has developed a lot of play, needs backlash adjustment
(d) wheel alignment needs to be checked as all bushings have been replaced at the front
(e) gear box is leaking oil, needs to be fixed

etc

Done. Had visited Shri Ganesh Auto Electricals (Lucas TVS service centre @Gadital) and the defective pinion was replaced.

Updates as of 25-Dec -

Added 220 ml EP 140 gear oil to steering gear box. On draining out the existing oil, it was found to be barely 50 ml :

Steering feels much smoother now.

After briefly experimenting with a 97.5 jet, am back to using a 102.5 main jet again and re-tuned the engine this morning. Switching to a 0.5mm gap in all spark plugs have resolved all driveability issues. The car handles like a dream now.

One of the rubber straps holding the exhaust pipe in place had snapped and was causing a constant rattle. The strap has been replaced and the vehicle is truly noiseless now.

All four doors were adjusted and annoying rattles are now gone.

Damaged paint was sanded off, the areas re-primed and painted.

The car finally looks and drives the way I have always wanted it to.

Had checked the compression in each cylinder this morning. The results were identical in cylinders 2,3 & 4 (@130 psi). Cylinder 1 showed up as 125 psi which isn't too much of a difference anyway.

Nice to hear that you are finally able to enjoy the drive. Also I really admire the step by step approach of yours in tackling all the issues car's throwing at you .

Yes, after a really long wait, the car can sustain 80+ kmph for extended periods with ease. Acceleration is smooth and doesn't require any effort.

I can now keep up with (and at times do better than) modern day traffic.

Testing included a to/fro trip to Wakad on 25-Dec around 10 PM (a total distance of ~90 km).

The temperature needle didn't even touch the 1/4th mark throughout the journey.

Glad to know it passed the test & is a good cruiser in modern traffic, speaks volume about the quality of work carried out.

BTW in normal circumstances the temp. needle should be at half mark, do check if its working fine

It does work

I have seen it touch the half-way mark whilst driving in bumper to bumper traffic during rush hour.

01-Jan -

The timing pinions & chain were replaced. The car now idles like clockwork even at 620 rpm and exhibits no hesitation/flat spots during acceleration.

Both wheel cylinder assy's at the front were replaced with new TVS Girling units. The brake linings were replaced all around.

The car now pulls slightly towards the right on hard braking.

This would be corrected with minor adjustments over the weeked.

Wish everyone a very happy new year !

12-Jan -

Had driven the car down to Mumbai over the weekend in order to check for possible reliability issues.

The car sustained 80/90 kph throughout the journey on the Mum-Pune E-way without any issues/over-heating. At one point, the speedo had touched ~115 kph but engine felt strained so did not continue at this pace for long.

Visited Sion Koliwada for some spares.

Picked up an used bonnet from a scrapped PP taxi which would come in handy (the one on my car had suffered some accidental damage in the hands of it's previous owner).

Also got hold of an old two spoke steering wheel & air filter housing for the PU paper element type filter.

Though Elofic filters proved hard to come by, it seems that the filter element from the modern Royal Enfield 350 cc bike is a straight fit.

I attach some pictures of my car after the minor "plastic surgery".

This morning I found that the master cylinder is leaking brake fluid after a brief local trip. Will have to send the car to Javed's garage next weekend.

At Koliwada, came across an establishment where an old gentleman had quite a few restored fiats of different vintages on display.

The restoration seemed rather overdone but it was a lovely sight.

The shop was named J K Auto.
Address:Shop No. 555, J.K. Basin Road, Sion Koliwada, Mumbai - 400025.

Wonder whether anyone else has had a chance to visit this place.

Dude, what a lovely car you have got! my bad luck I just left pune, else would have surely come to have a look at this beauty.

Was a happy owner of a Padmini for 7 years! miss those days badly, but its threads like these which make me happy again.wish you the best.

In case you wish to make it a bit more comfy , can easily fit padmini S1 bucket seats. I had them fitted in mine and it was very comfortable. Can try kurla for 2nd hand seats.

Hi silverado,

Thanks for your comments. In case you happen to be back in Pune, you would be more than welcome to pay us a visit.

I find old S1 parts to be a rarity these days and people are quoting really absurd prices for trivial items.

Hence, I have decided to stay stock as far as possible.

On the same note, I find the bench seats to be quite comfortable (and my daughter prefers it as it allows us to be seated three abreast).

But many thanks for the advice anyway.
