I spoke with Doug at Pierce Manifolds in California and he was quite helpful. Three sets of rebuild kits are on the way. Thanks for the advice. I will examine these bits closely before installing. The inside diameter of the needle valves was important and they are stamped on the outside of the base of the valves. |

Even Pierce Manifolds can make mistakes. A friend had a pair of 44IDFs done by them for his Fiat (he also owns a TR) and though they looked great, there were problems with the throttle plates, the jets were swapped wrong, etc. Take a close look before using and if anything is wrong, kick them back. I'm sure they'll make it right. |

Thanks Raymond for the tip regarding the fuel scum. The shank of the needles, indeed, is coated with an opaque film. But, the middle carb leaks the worst and it has the biggest horizontal wear mark where it has been seating - or not in this case. So, there may be two problems: the fuel scum and the wear grooves. The needle valve and seat in the front carb looks much newer than the others, so may have already been replaced, but not by me and I have owned the car since 1974. So, somebody a long time ago has been into these babies already. Outside of removing and cleaning the needles every month, what is the best approach to avoid getting this fuel scum problem? |

Hello mr Long,
It is great to read about another PF coupe being restored. Mine was 1415GT. I got a case of the stupids and sold it. Since recovering i have not found another. Servizio did the drive train, the late Al Holbert's Porsche builders did the body and I did most of the rest. If I can help in any way please ask.
We have run into a epidemic of needle valve problems in the last five years. Todays fuel has added new problems to carburetors.
Closely examine the needles with a magnifier. If they do not show signs of wear they could be coated with new gas gum which forms in 30 to 90 days. The fuel in Webers evaporates and the float sits open and wet. The gum forms but not evenly over the surface. Float will not seal. Clean the float and its seat with carb cleaner or spray brake cleaner.
I am sure you realize that care is to be taken so as not to scratch parts.
Besides the gum, the new fuel with alcohol is thinner and leaks a lot faster. This is all a result of EPA agreeing to make Archer Daniels Midland happy people. ooooops probably not legal here.
MrC

If you cant find parts and have a lathe you can use some 1500 grit sandpaper and resuface the needle, I did this once and it worked fine. |

Mike at Pierce is the final word on Webers, they a piecing back together a set for me now, that should by all rights be thrown out due to some horrible work done at a prior time. I have used them for at least 18 yrs now, back to the World Ferrari days, where we ran a whole gaggle of 250 race cars in Vintage racing. If I am not mistaken, 0581 is here in Denver now, gold in color. I did some work to a Boano a few yrs back, and I think that was the number. I am pieceing back together the engine on a Ser.1 PF cab right now, that the Webers that Pierce has, belong to. |

Not a "world renowned Ferrari historian," ???
Come on, Wayne. If it was made before 1960, you know whether the owner was 'Haynes' or 'Jockey'. |

Sorry, Ed. I didn't realize that I was accosting you. No harm intended. I'm no "world renowned Ferrari historian," but I am somewhat obsessed with these old cars their histories and make a point of jotting down notes about them whenever information is avaialble.
Welcome to the board. I hope you find what you're looking for. |

I have Pf coupe s. n. 1747. The build sheet - the factory sent me the original with hand written notes in blue pen - indicates that it was finished in March of 1960. We bought it in 1974. I owned s. n. 581, an inside-plug Boano that I rescued from an auction in Portland. For a time, I was the only kid on the block with a pair of 250's in my garage. It had been painted ugly yellow with a bristle brush. I sold it to an Air Force Major in 1983 so I could go racing again. How would you happen to know that I once owned that Boano coupe? I shall try Pierce Manifolds and Inglese Inductions, many thanks. |

Wayne,
I think you need to explain that you are a world renown Ferrari historian before accosting a first time poster.
Matt
JRV,
I suspect we are going to have the same issue very soon. Would Ferrari be of any help on these older cars?

Ed, welcome to F-Chat. Do you mind if I ask which PF coupe you have (s/n)? Also, are you the same Edward Long who once owned 250 Boano 0581 GT?

Have you tried Pierce Manifolds 800-874-3728 or Inglese Inductions (don't have the number handy, but can get it if you need it) ? |

I have three Weber 40 DCL6 carbs on my 250 built in 1960. The needle valves no longer are seating and they allow too much gas into the bowls. Anybody know where to find replacement parts for really old Webers? |
