So, I took apart the carb today and found a hair line fracture on the main nozzle in one of the carbs it's about 1/4 of an inch long. incendentally, that carb is running rich no matter what adjustment I do to it. What exactly does the main nozzle affect? do you guys think the fracture is the cause of it running rich?
It lets more fule in as the slide go's up so it will make it run rich if it's worn or in you case fractured.
Had the crack soldered and put back together. The cylinder is no longer running rich. Interesting though as too how can the nozzle crack. unless it was damaged when I had the carb serviced by a shop <!-- s --><img src="{SMILIES_PATH}/icon_mad.gif" alt="" title="Mad" /><!-- s --> Here's a picture of the crack it looks big, but it's actually thickness of a hair or even thinner, and the length of a finger nail.
hmm so that must have alloyed alot more fuel to enter the cylinder... I dont see how it would have cracked..unless, like you say it was done while being worked on.
Being brass you will be able to solder it up, or silver solder. The trick is not altering the jet size with the molten filler material. Regular solder is softer but will need a liquid soldering flux to get the crack clean enough for the solder to stick.
