    hey, i just bought my staton chain drive robin suburu 33.5 cc, 1.6 hp, inside mount kit, the instalation went pretty well, and i was just wonderign if the 22 once gas tank is the only gas tank you can put on that set up? i was wondering if you can upgrade to a bigger gas tank or is there just not enough room for one?

    There's not enough room for a larger tank, but an auxiliary tank can be 'plumbed into' the gas line return, so that the primary (existing) tank stays full until the auxiliary tank runs dry...

    The existing return line is piped to the return of the new tank, the gas line from the new tank goes to the return line of the existing tank, and the vent on the existing tank is blocked.

    As you pump gas out of the existing tank, and a vacuum forms in the existing tank, this siphons fuel from the new tank. The overflow fuel from the carb returns to the new tank.

    Essentially, you extend the fuel-flow loop to include the new tank.
