[prkahrvat]

Hello everybody, long time no se, hope you all are well.
There was one fiat 126bis standing, and ready for making a cube of her. Fortunately i found her one day before.



there was a little work:



new front wheels and tyres 135/65 12 from my 126p
new back wheels and tyres 155/60 13
recharged battery

movies:
first movie is starting her after long time
and second is she is working alone without support battery, and without choke

thats it for now

and now problems:

she was working just fine, but other day when i come she dont want to start again. it is very hard to start the engine and if i start it it is very very noisy (and i know how noisy she can be) and she is working like its 2 tact engine. could it be ignition distributor? ill try to fix it today
second problem is, someone whos was that car before forget to put screw on water cooler, but that one screw what is beneath cooler, which is used to sluice water. there is no shop in Croatia selling this screw so i try to find replacement. i tried 13 M8 screw but it was too small. does anyone know what screw can be replacement?

thank you all!
