Mystery fuel leak...
I have been riding since I got the carbs done, and everything has been great...Until last Sunday. I rode to church (15 miles) and when I got there, steam was rising all around me. As it turns out, I broke a hose clamp under the tank. Rode over to a buddy of mine's, lifted the tank, replaced the clamp, and rode home.
That night, the garage filled with the odor of gas (which permeated the house, thereby annoying my wife and daughter). I thought I had partially pulled one of hte fuel lines off of one of the carbs, but that was not the case. Monday night, I tried to find the source of the gas leak. It appears to be in the rear carb, and it initially looked to be coming from the coasting richener valve, as the drips seemed to primarily be from the lower screw on the cover. I figured that the lip on the rubber diaphragm had come out of the groove on the carb face when I reassembled it. So I pulled the cover, cleaned up the gas, and reseated the diaphragm. Note that it felt kind of tacky when I was placing it, but no more gas seemed to be leaking...Until that night. Again, the garage and house filled with the scent of gasoline. I went out and sure as shooting, the carb was still leaking.
Tonight, I had a chance to look into it, and the coasting richener area was more or less dry, but there were signs of dampness in the pilot air mix screw hole, down toward the throttle cable attachment, basically all of the areas circled in yellow on the attached picture. (Please forgive the blurriness)
Does anyone have an idea where the gas may be leaking from? I haven't seen any problems with the front carb. I would like to get this fixed fairly quickly, because this weekend promises riding weather, plus I really don't like keeping the bike outside. I already intend to replace the coasting richener diaphragms next week.
