I recently installed the dual tank mod after suffering engine idle problems. From my point of view the fuel flow is good now. but the engine still pushes air back toward the tank. once the engine goes off, I takes a lot of patience to bring it back to live...once its running the engine is performing good but it suddenly goes out and then there is air in the fuel tube.
I'm a little clueless now! Is this a carburator problem or a general setup problem?
what engine would be worth to upgrade to ? I'm using rotostart right now...
thanks for any tips
