That sounds like good advice Jim.... and It is well taken. But, why does the run on problem go away when the engine is adjusted this way? It does work, if all other things are adjusted to factory spec... I have done it several times. This is to fix the FI run on problem, not to have every engine adjusted this way. Now, valves do expand and contract depending on temp ( just like any metal does) but .002 more REALLY does not harm the drive train... I have one in the driveway that has 47,000 miles on the engine with it adjusted that way. The quality of many VW air-cooled valves are not the best... the garbage that some sell on rebuilt heads is beyond fathom.... and the cooler running valves seem much happier. Any of you ever notice how your exhaust valves are always getting tight after a few thousand miles when set at .006? Remember I said that setting them to .008 HELPS TO SEE if that stooped the run on... meaning set them back to .006 if it does not help. I also mentioned that this is for troublesome cars..... not all cars. I learned this from a man that ran Auto Haus Porsche/VW back in 1975... and he has raced and maintained both types of aircooleds for more than 40 years. He is a trained factory mechanic that started by working at the Wolfsburg plant as a teenager on the assembly line and worked his way through the pack to be a head mechanic for the Porsche Racing team for 4 years. I do have a lot of faith in his background and his talents. Call me crazy...I know many of you do, LOL..... but it seems to work. I am not challenging you Jim, I respect you very much, but I do have those questions. You maintain a level of knowledge on these cars that is amazing. As a second note...... there has been some conversation about putting the gas petal to the floor to start a FI engine. I originally saw this on the back of a FACTORY sunshade in 1969 in Germany. It is also printed in the owners manuals for FI cars under starting hints. I have it printed on page #20 in my 1973 owners manual. It reads" Always fully depress the accelerator pedal first, and keep it depressed while operating the starter. This holds true for a cold engine and an engine at operating temperature no matter what the outside temperature is. The electronic fuel injection system, with which your Volkswagen is equipped, automatically supplies the right amount of fuel that is required at starting". I am not and never will anything beyond a guy that loves these cars and has worked on them for some time...... I just know what works safely for me on my cars. ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org
