I ordered the kit to rebuild my carb, got it, looked at all the schematics for my carb while waiting for it. Got the kit, and started trying to match up all the parts to the schematics, got a little scared by all the extra parts in the kit as compared to the drawings. I pulled the carb off and found that the drawings were exactly right and there are only a few parts besides the orifices. Am I missing something or do they send extra parts so that the kit will fit various carbs?
