I'm an advocate for DIY auto mechanics, but the one thing I am happy about getting done professionally is my carby.
Got it rebuilt a couple of years ago for a couple of hundred bucks. Has run fine (not perfect) since. Saved me a lot of time suffing around on it.

They are very very complex things. Enigmas (sp?) even.

Sounds like your idle jet for sure, Shayne. My idle jet blocked just last week and after 2 days of putting up with poor running hoping that it would unblock itself I decided to try Brayden's old trick of swapping the plug leads on cylinders 1 & 3 and cranking the engine over until backfired into the inlet manifold - blowing any crap out of the carby.

This fixed the problem initially, but as all this remedy really does is blow anything blocking the jets straight back up into the fuel delivery system, the problem soon returned. I administered this remedy once more and the engine has run fine since.

Give it a go. Run the engine until it's at operating temperature, stop it, swap the leads on cylinders 1 & 3, then proceed to crank the engine with a moderate amount of throttle applied. You'll hopefully hear the occasional pop come up through the inlet manifold. Stop cranking, swap the leads back over, and see how you go... :wink:
