I'm planning to build a Venus II and I'm wondering what Y.S. model is preferable for good perfomance?

the 110

Can the 110 be invertly mounted? Also, did you use with or without pump? What muffler did you use? Thanks for your reply.

I do believe the YS 110 has abuilt in pump as do all YS engines, shoudnt be a problem mounting it inverted

Yes, the engine has a built in pump and comes with a frond mounted regulator. With the YS you can place the fuel tank almost anywhere and the engine will run beautifully. The 110 will give the Venus 2 great power.

Enjoy

Thanks for you reply, Jet, Nath. Btw, what kind of muffler did you use? I'm refering to the muffler that canbe positioned under the cowl.
