Driving my beetle today and all was fine then i accelerated hard from the lights, for the remaining few minutes of the drive the engine was hesitiating alot when trying to accelarate again and also backfiring heaps. Not knowing much is there something stuck in the fueling or anything like that and can someone tell me what to do in the most basic way?
Thanks

Quick eyeball check of the linkages and the spark plug leads is an easy one.
I was on a run once where the Beetle was running rough all of a sudden, but I didn't have a chance to check why, and after an hour of driving and getting to my destination, I had a quick look and found a plug lead off. 1 hour on 3 cylinders!!!
It idles ok when warm even accelerating it really struggles and shakes and backfires every second pretty much. The leads all look ok i think, i couldn't really get my hands around to check the front one but i'm sure they where ok.
Where is the accelerator pump and how do you check whether it's leaking or blocked? 😢

the accelerator pump is located in the carburetor...
its a small square shape with 4 screws to undo to check the square diaphram...
Every time the accelerator is pressed the accelerator pump squirts fuel into the engine...
but - if its NOT idleing correctly...
could be a spark plug lead loose...
make sure the leads are on the spark plugs correctly...
Take the top off the distributor - unclip the two clamps..
spray inside the cap with WD40 or similar and wipe it dry with a cloth...
also wipe the rotor - as cracks can appear in Dizzy caps in which the high voltage spark can short circuit...
the cracks can be not Visible...
it sounds like the engine is firing wrong....
No leaky exhaust or inlets manifolds???
I don't think its the accelerator pump...
You can't really drive without the accelerator pump working.....
I have twin Kadrons, and this is pretty much what happens if the linkage falls off one carburetter. Move the linkage, and check that it is still connected to both carbies.
Have a look at the points (possibly closed) and condenser,even though iy sounds like a classic fuel problem.Look outside the square because it is not always what it seems.

I've double checked the linkages and it seems good. The fuel filter has a bit of dirt in the bottom of it. What do i need to do to clean it? Sorry if its a stupid question but a don't want to do anything bad. Is it just a case of cleaning it out and putting it back on or do i need another one. Will fuel come out while the filter is out? Any tricks to doing it?

I figured i'd try changing the fuel filter and if that doesn't work take it back to Vintage. It would cost more in petrol to get to vintage than the price of the filter so i got nothing to loose and a bit more experience with my bug, plus i wasn't real keen driving that far the way its running either 😁

I tightened everthing i could get to and nothing seemed loose so i'm hoping its just the filter. If this rain stops i should be able to change it today i hope.

The fuel was Caltex 98 octane. Was good for 3/4 of a tank so i'm assuming it's not the fuel. By the way, where do you all get your fuel filters as i went to Supercheap and they didn't have anything for beetles. Does it matter which one you use? There was a ryco which looked like it would fit ok.

Woo hoo, beetle is now running normally again. Not sure what it was exactly as i unplugged all the leads and tightened everything i could but it wasn't the fuel filter as i didn't replace that. I guess it was the leads so thanks everyone. 😀
