Hesitation

Hi all. I'm new to Beetles, so I wonder if you could assist me. I have a

1972 Beetle (South African Edition) that starts and idles great. However, if the car is driven, it reaches about 2500 to 3000 rpm without problems and then seems to cut out or stutter. You can't get above 70km/h in fourth gear. I suspect that it is a carburettor problem. Are there perhaps two circuits - one for low revs and one for high revs? The strange thing about this problem is that if the car is in neutral and I accelerate, I cannot hear the car hesistating. I haven't dismatled the carb, but have used one of those liquid carb cleaners that you buy from spares shops. No luck. Any comments/ideas would be greatly appreciated.

Regards, Elvin

Start with the basics Fuel Filter Air Filter Did you check the ign points, distributor cap & rotor? and those Intake Manifold boots for any leaks? Valve adjustment Fuel Pump fuel pressure Maybe a weak ign coil or bad spark plugs or wires

good luck!

That sounds to me like fuel starvation. Not enough flow of fuel from the tank.

Could be a clogged (in-line) filter, or clogged mesh screen in the tank outlet fitting, or screen inside the fuel pump, or a defective pump.

One test: Remove the fuel hose from the carb. Extend the hose into a petrol can. Run the engine (it will run for 30 seconds or so) and watch the flow rate from the hose. The spec is 400cc per minute, but if you only get a dribble then there is a flow problem.
