Hi,
(Fiat 126 652cc engine fitted in a 1970 Fiat 500.)
This car had sat for over a year and it started immediately, although with an erratic idle (kept dying unless foot on accelerator.)
Drove it about 5 miles and it ran OK although it kept cutting out at lights but started again OK.
Then, the next day, driving along about 50mph, it started spluttering and coughing, revs dropped and it cut out.
As I had not tool, I called the AA who removed the carb, cleaned all the jets, put it all back but it just wouldn't start for the AA man so he towed me home.
Today, I removed the carb, cleaned all the jets again, checked the needle valve is cutting off fuel and it's all fine.
Removed the plugs, cleaned them and checked they spark which they do. It's a Weber carb- see attached picture.
But still it won't start! Checked plugs after trying to start it and they are wet with fuel so it's getting through to the cylinders.
It has electronic ignition so no points.
What could be wrong that it was running and then spluttered cut out and now won't start?
One other thing I noted: the fuel return from the carb to the fuel tank has been blocked off so there is no way for excess fuel to make it out of the carb.
Could it be flooding the carb due to this?
But that's how it was for years before when it was running fine so don't see how it can be that?
Any ideas?
Thanks
Peter
