Engine stalls...

Post by Pete »

Bit odd this but I'm posting this on behalf of a mate.....

Ok, he's got a pokey 1275 S lump with split Webers and every time he goes out in it the bloody thing stalls when coming to a stop at lights/in traffic etc once warmed up and will not restart for a few minutes. It always starts fine from cold. I borrowed it once a couple of years ago and it did this on me, restarted after a five minutes.

I thought fuel, either it fouls the plugs when idling hot (is that possible ??) or more likely it's boiling the fuel once hot ?

I know ..'how long's a piece of string'.. but any suggestions welcome.

Hi Pete,

Does it need choke/throttle pumping to get it going from cold? Sounds like it could be lean when hot....maybe :?: Have you had your string calibrated recently.

Im guessing it's too rich at idle.... So you are flooding when coming to a stop. A wide band would tell you this for sure. Then you need to find out why...
