FAMILY="SANSSERIF" PTSIZE="10">It sounds like a pumped set-up. The tank vent
should be left open during operation, to allow air to enter as the fuel is
used up. The caveat is that the vent will often syphon fuel out if the vent is
out in the slip stream. I use a YS check valve to allow air in but no fuel
out.<BR><BR>The 2 stroke 120 engine type should be able to turn a
16x10-11; 17x9-10 fairly well in the usable rpm range we
need.<BR><BR>Why such a large engine on such a small
model?<BR><BR>MattK<BR><BR><BR>
