This is a very difficult to get item to get! Many have said soaking the existing one in kerosene for a few days will do the trick, have not done that yet as I am still trying to track down a new one. Wondering what the success rate has been with soaking it in kerosene, also wondering would WD 40 do the same thing. Would hate to ruin the one I have, which is original to the car!

Ian did you get your starting issue sorted out? Yes we did Mark, now I can start the car and I let it warm up as it stumbles until I get close to operating temp, then it works nice, pulls strong and smooth. Idle is good if I have been just around town, if I have run it at {hwy speeds plus} the idle is too low and can stall til engine cools a bit. I have never even got close to the m on the temp gauge just so you know I am not abusing it!Thanks to the new heads I think, supposed to run cooler with those. Ian |

Ian I checked but did not find that I have any decel valves. Found this on Brad Anders site Porsche number 022 133 551 Bosch 0 280 160 102 1.7L 1972 - 1973 1970 -1971 1.7L 914's didn't have a decel valve, because their ECU cut off the fuel flow on overrun.
