Hi Guys ím trying to fix the old mans 500 C topolino (1950)
My native language isn't english so to translate into specific mechanics jargon is going to cost me some effort but i'll give it my best shot.
The car used to run fine, a bit neglected but fine. Untill my brother(not techincal!) took it for a spin, the car started to make noise and he drove it home.....
Afterwards me and my dad diagnosed a broken piston pin sleeve on cyl 1, I replaced this sleeve myself and put everything back together and it worked again. Afterwards we never took it for a drive for the next 8 yrs and it became stuck in the garage.
Than we wanted to drive it again and brought it to a garage because i lacked spare time.
Its had a complete overhaul from a specialist garage:
- Compression check
- Engine oil
- Gear oil
- Replaced the ignition, sparkplug condensator, rotor contact etc.
- Fuel pump
And also everything to make the car safe to drive(not mentioning details as they arent engine related)
The problem:
The car (cold) starts fine and runs like a charm. Once it gets to the temp range of 70-80 celcius (158-176F) the car start to hicckup, lose power and fire from the exhaust. As the temp rises further te car becomes undriveable due to lack of power. (176F+)
I find it weird as this is related to engine temp.
I sprayed around the carb with some engine start spray and the engine doesnt seem to be pulling in 'false air'.
Checked the spark plugs and they were black.
the carb is a Weber 22 DRS, using needle: 45 and 92.
Looking for some advice as where to look.
