Hi,
I have a new car that I'm working on that hasn't been run in at least 3 years (maybe not since '86) It's in pretty good shape but one of the carbs had water enter into the throttle body and sit on top of the carb causing rust. Now it is rock solid and won't move. (IMG:style_emoticons/default/hissyfit.gif) What should I use to brake up the rust? something like CLR? Not many cars in here using the 40 Pii-4's, why is that? I have searched on here for info on them without comming up with much. Most of my info has been comming from 356 sites. |

A lot of folks say Solexes are finicky, but if dialed-in correctly, are great carbs. That's what I've always used on 356/912 motors.
I have a set of Weber IDFs in the same condition as yours (possibly worse). I've tried WD-40, PB blaster, carb cleaner and a U/S tank, all with negative results. Diesel fuel has been suggested as a good penetrating fluid, but I'm going to try some Berryman's carb dip next, since I already have a big can of it around here somewhere. |

I'm gonna try the CLR. My friend saved the heater core on his Audi with it so I'm expecting good results. (IMG:style_emoticons/default/unsure.gif) |
