Petrol smell from exhaust

Neil 244 DL 79 · Nov 14th, 2021, 15:39

My 244 b21A with single SU carb has a fuel smell from the exhaust. Also turning the mixture adjustment screw on the carb seems to have no effect - I'd expected to hear the engine tone change. Therefore I think I'll take the carb off and send it for rebuild. Does that sound right to you guys? I'm far from an expert, if you think you know better please advise.
Thank you
Neil

The smell suggests it is running rich

What have you been adjusting?

You might just have a sticking float, might just need a needle and jet replacing. The only thing that usually warrants sending them off for is a worn spindle

It is probably worth going through the set up procedure before you start taking parts off the motor car (see the link in this post for the green book):
