aha ! that makes sense .
So , unless I'm using the car in really cold weather (unlikely ...) I can replace the silencer etc with a "Sports Exhaust" with no impact on any performance / starting .
Really appreciate your response and didn't realise there is a Parts Catalogue on this site !
Cheers

Fiat 126 Mechanical Problem Solving / Strange noise from the speedometer
« Last post by bertvb on July 18, 2023, 11:20:32 PM »Hi all,
I've recently installed a 5 speed kit from Nanni Ricambi.
When I installed the speedometer, I noticed an unusual ticking noise while rotating both driveshafts in the forwards direction. However, when I rotate them backwards, the noise disappears.
I've attempted to resolve the problem by re-installing the sensor, but unfortunately, it hasn't made any difference. Without the sensor, the noise completely disappears.
I'm perplexed as to how I could have incorrectly installed the sensor, as it seems straightforward. If anyone has experienced a similar issue or has any suggestions on how to address it, I would greatly appreciate your advice.
Best regards,
Bert

« Last post by Minijohn on July 18, 2023, 07:19:00 PM »Hi
I don't know for certain (my car is air cooled) but that sounds like a system for feeding warmed air to the carb in cold weather to prevent the carb from icing up.
Later.......
I've just been looking at the parts catalogue in the Subscribers section ...
the reinforced hose which you say is vented to the atmosphere is the air inlet
the air travels along that tube and then passes over the hot exhaust manifold
the heated air passes to the air filter box along the 2nd reinforced tube you mention
The flap is for you to bypass the exhaust heated air and send "normal" air to the filter.
You'll only need the heated air on cold/wet days - which is when I guess you won't be driving your 126 anyway !!

Fiat 126 Mechanical Problem Solving / 1990 126 Bis - exhaust box + assoc hoses .
« Last post by PeteB on July 18, 2023, 06:48:19 PM »Hi - Just joined the forum having just bought the car .
So , on looking at (and removing) the existing silencer I noticed that two reinforced hoses are fitted , one going from the exh manifold to the air filter box , the other going from the opposite side of the manifold “tube†to the rear quarter of the car and simply venting to atmosphere .
The air filter box has a mechanical flap (hand operated) to either allow air to enter or not .
My thought is that this hose arrangement is some firm of vacuum system , but am struggling with “why†!
Also , I see that a replacement “Sport†exhaust doesn’t have this arrangement on the silencer - so presumably it isn’t really necessary (?)
Would like to hear from anyone who could shed some light on this - have attached some pics .
Many thanks !

Check the ignition coil also.Check the contact set on the distributor and check the bolt where condenser is connected with the wire from ignition coil.The bolt must be fitted with plastic washer inside the distributor, but he can't have contact with any metal part from the distributor.

I did not see a plastic washer.

« Last post by Njkip on July 09, 2023, 07:51:39 PM »Is the coil an oil cooled one? I know that when they start to break down they will work until they get hot then you'll have ignition problems, and back firing etc....when it's cooled down it will work fine again until it warms up until it finally packs in.. I remember having the same issue when I had my old mini...in fact it backfired that bad it blew a hole in the exhaust. Soon as I put a new coil on problem solved....
