Fiat 126 Poor Runner :(

[Blonde126]

My 126 started to run a bit rough, and I noticed that there is a lot of oil seems to be getting sucked into the carb after a few minutes of running. The engine won't idle without choke, and it seems to have an inconsistent misfire to the point where it feels like it's on running on one cylinder.

Also someone has fitted a temporary washer on the spring of of the oil filler cap, could this allow oil to be sucked through to the carb?

Here are some pictures of inside the carb:







Could anyone be of any help? Thanks!

Hi,

Not quite with you but sounds like you need to have a compression test done on the cyclinders.

That happened to me on the M1 and all because the disc was missing from the filler cap. been fine with a new cap plus their cheap enough

Thanks I'll give a new oil filler cap a try and fingers crossed that cures it!
