I try out this newly bought used motor on the week end, I found out there is a problem on may be the gas line, the original owner had the same problem but he claims was his gas tank leaks, therefore, I use my other tank buit still the problem, when I start the motor, it runs for some seconds and it seems to die and I have to keep prime (pump) the gas at the tank in order to keep it running, actually the motor runs good, I thought it may have some leakage along the gas line, but I could not see any leak any where, I am not sure is there a gas pump on this motor? may be some one can give me some professional help here, and thanks in advance
