i have an old beetle came from my grandfather. It has a 1500cc engine. all stock. I change the cylinder heads with a dual port heads stock from a 1600cc engine. I also change my ignition system with MSD 6a and high tension wires stock exhaust. 009 dist. and a weber carb. 2bbls idf 40. My problem is that it always has too much gas in the pistons or sometimes its ok. could it be the Spark plugs or the carburator??

At a guess I would say the carburetor...

The jets in the carburetor could be any size.....

depending on what the previous owner put in them, or what they came with....

My Sons runs a Holley bugspray carburetor and his exhaust is always sooty, and it uses much more fuel than a standard 1600 engine....

but the car goes very quick....

One of the jets has actually fallen out on more than one occasion...

luckily it falls into the fuel bowl....

 

Also, it may depend on how much You push down the throttle, when You accelerate etc.... or

 

If the float in Your carburetor bowl, sticks or is full of fuel, when the bowl fills up, the excess fuel will overflow into your engine inlet manifold and into your engine....

The original distributor is much better than a 009...

009s are just a cheap replacement... and have to be timed , at 32 degrees with the engine going, with a strobe type timing lamp...

009s cannot be timed at idle....

My Son has just spent a lot of money on His webers, to stop them using so much fuel... 

as they were set up for a much larger engine....

He bought new venturis and jets to match his 1835cc engine...

You need to go to a Weber specialist... or a Weber VW specialist...
