Question

Answer
 Hello Sam:

 You should have No Worries about Air in the Fuel Line. If you have the Twin Cylinder Engine with the Pump at the Carburator, you want to make sure that the Gas is Free Flowing at the Carburator. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.

 Good Luck

 Respectfully

 John
