I am trying to get my bike to start and I am having trouble. This bike has been sitting for a long time and I am trying to get it back up and running. So far I have flushed the coolant, changed to oil, installed a refurbished carb, Cleaned the Gas tank and installed new petcock and battery. Now I am trying to get the bike to start and I isn't working. I checked the spark plugs and they are working just fine. The gas is flowing out of the tank but it is leaking a little bit from the hoses because the hoses are slightly to big for the new petcock. When I spray starter fluid it sputters a bit like it's going to start but it doesn't start. I think it's a gas issue but I'm not entirely sure how to diagnose and fix it. Is there anything I'm missing? What should I try next?
