I'm with, "I'm with stupid" previous poster
I've had similar problems with almost every petrol (gasoline) car I've owned
So *might* be just that, and be a co-incidence it's while you've had it to work on
Unlike old carbs, jets sometimes hard to get at to remove and clean, but a repair can usually be effected thus
Take a large cloth NOT handkerchief, but an old tee shirt for example. ball up in your hands, with engine idling and aircleaner removed
temporarily hold ball of cloth overtop carb air intake and rev the engine up gently then ease off, several times, (use hand on throttle linkage) while temporarily choking the air intake with balled cloth (don't let the engine quite stall out)
This creates a MEGA size vacuum which will normally suck through any gritty bits right through the carbs jets. This system can be done for free, and on side of road if necessary, as all you need is a large cloth DO NOT USE SMALL CLOTH like a hanky that might concievably get sucked right in !
ALSO you can use the following AS WELL as the above...........Note that spray cans of **carb cleaner** can be bought at your local auto parts store. Use as per instructions on can, but usually you remove the air filter, and with a warm engine/choke off, run the car at a fast idle (use hand on throttle linkage while spraying down the throat of the carbs air intake, several good sized shots from the spraycan. Then turn off engine, and spray again. Then wait 5 minutes, start up and drive away (allows some of the solvent to seep down inside other carby bits)
I bought a can of this carby spray for about ten Aussie dollars contains about 450 gr/1 pound and gave my car several treatments, plus did several friends cars, one decent large treatment each (heaps of spray). My car needed several treatments to come right, but has been perfect for more than a year since. so a can gives you 10 to 20 treatments easily. And with many older cars fuel hiccups, one treatment would probably suffice
cheers
