I just bought the bike it sat for many years and is in really really good shape. I brought it to the shop to bring it back to life. The shop called me and said the bike was ready so I went to pick it up. when I got there they where having trouble getting it started, they work on it a little more and got it started. the shop told me that they put a new petcock, changed the oil and plugs they also told that you have to put the petcock on prime to get it started and also use the choke. what is the problem any suggestions oh I also put a new battery in. It at the shop now <_<

Does she run ok with the petcock in the normal position after starting?
