So, in my continuing fuel starvation saga (another thread), I'm almost ready to rebuild the webers. Rode her hard again yesterday, and she ran pretty nicely for awhile and eventually started to starve very hard at really hard throttle. Took a very good look in the tank, and the walls look pristine, but in the circular baffle area where the sock is, there were many very tiny pieces of black crud, and the sock, though very hard to see well, looked pretty dark too.
Opinions? Also, I'm thinking that since my fuel filter was pretty clean, that the sock might be my real problem...should take care of that before making the carbs clean and possibly getting more crap in them. If I do pull the tank and replace the sock, shouldn't I replace the fuel line back to the engine? Any threads on that? Can I just hook a new line up to the old and pull it through? Thanks in advance, Ken |

Changing the sock and fuel line is a good idea. I'd even change out your fuel pump. Unfortunately, thats not your problem. You can't adjust float level without cracking the carb open. You can assume it's fine and go with larger mains and see what happens. You'll be out the cost of the jets if that wasn't your problem. You will have gotten away with not cracking open the carb if it was. I do have to say a lot of guys with lean transition issues seem to be running a 115 main and a F11 ET. Thats what comes in the 40 when they come from Weber. I always wondered why when IMHO the 125 was the more suitable jet. I guess it's so they can sell you more jets.

Is it sufficient information to order "125 main jets for an IDF 40", or do I need any more specific information like the full carb ID number?
