Converting to carbs costs a medium sized bundle up front, plus you are guaranteed to need a lot of tuning and adjusting of jets because the sets you can buy in the aftermarket will not likely be jetted properly for your engine when you get them, in spite of what the people who sell them to you will say. There is also the problem of even FINDING a good source of jets in various sizes these days, and of getting all the parts that you really need to install the conversion. Carbs will give you good performance with poor emissions. If you live in CA, you should not consider this option. Another thing to consider about a carb conversion is that you will not likely be able to get straight answers about things like what your timing should be, because you are likely to have a slightly different collection of parts from everyone else here. Diagnosing and repairing your FI requires that you study the system and spend time asking questions here. You are unlikely to find someone near you to help, because these systems are pretty old now. Once you find the problem, some parts are certainly expensive if bought new, but there are good sources of used replacements here on this list. MOST FI problems can be fixed rather cheaply. The expensive parts are seldom needed. It's also important to understand that many problems initially blamed on the FI are eventually traced to some other system, like the engine, the ignition, or the gas tank, which would have affected a carb conversion, too. I should make it clear that I am a proponent for FI. My suggestion would be to start down that road first. Either way, the first thing to do is to learn how to do a good complete tuneup and do it. Make sure the valves and timing are adjusted right and that the advance mechanisms are working right. Then check the compression. Finally, in defence of the FI. Once you get it in good shape it will be more reliable and smooth under all conditions that a carb conversion. - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- Search old messages on the Web!
