Running Rough

[steve pring]

Hi

I think I've just experienced exactly the same symptoms as old son had.

Funnily enough just before my mot and after a long lay up.
Sounds as if running on 2 or 3 etc.

I've drained the tank and ran engine till it stopped, then added some fresh fuel.

Still the same symptoms exist. Would taking it for a thrashing help?

Mike suggested blocked pilots and/or idle circuit passages.

Whats the best/easiest way to deal with this and how do you drain the carbs?

Any other things I should also look at preferably in a trouble shooting order?

Many thanks
Steve
