Hi, just got in a mexican beetle that needs some help. it knocks pretty badly and its running way too rich. it is a 2002 mexican beetle. we have worked in this car before. we reset the DME and it started to run much better but now its worse than ever. also, if we find out what the problem is, does anyone here know where to get parts from???? PLEASE HELP!!!
THANKS!!!!!!!!!!!

by mexican, do you mean it is a new original beetle that you imported or a new beetle? Because both are mexican. Also what engine do you have?

it has the 1.6 liter air cooled.

I used to have a really bad knock in my engine, and it turns out, the crankshaft and the flywheel had separated. I had to take it to a mechanic, and he pulled the engine, then reattached the flywheel with some Locktite. If it is running rich, you will probably have to adjust the air/fuel mix screws to get it right. If you don't know how to do these, you will have to take it to a shop, or ask a friend that knows a lot about them.

If it's an aircooled beetle then parts should be pretty easy to come by. If it's got a carb - is it a solex (or a copy of a solex) ??? It could be real rich for a number of reasons - but my guess would be that the idle adjustment needle has backed out and is allowing a load of gas to get into the cylinders.
The knock - does it vary with the RPM? These engines are pretty simple - you should be able to pull it out in less than 30 minutes - at which point you'll be able to examine the flywheel (the clutch will be bolted to it - the flywheel should not wobble at all) - if the gland nut on the flywheel is tight and the bolts that hold the pressure plate to it are tight you might have something going on inside the cases OR the cases may have separated a bit - but before I started into the cases I'd probably pull the valve covers - remove the rockershafts and check the push-rods (make sure they're all still together) - do NOT mix up the push rods or you'll have to re-adjust the valves - then I'd bolt the rockershafts up nice and tight - heck - I might even retorque the heads while the engine was out -
Check the main pulley on the front as well - check the fan inside the shroud (these can make a mighty sound when they come loose from the generator/alternator, by the way) -
Put the engine back in - fire it up and give a listen. If you tightened everything up it should run like a beetle -

Best of luck
