96 hx fuel system problems

[callmike2]

We've rebuilt the carbs on this hx and carefully followed all instructions to a T. It still wouldn't run. So we thought maybe an alternate set of carbs would help. So, we cleaned up another set and put in new parts. It still won't run. The spark plugs are always wet, and no start.

We've cleaned, adjusted and set everything according to the manual. Fuel lines, filters, everything new and changed. Compression is 150 on both cylinders. Rotary timing within specs. Oil linkage set to seadoo manual specs.

It seems to be always flooding rather than starving for fuel. We did use the same high speed and low speed jets. Those are set to manual specs. LS 1 1/2 HS closed.

Thanks for any suggestions you may have.

Read the sticky at forum top, go to links, watch the videos. Carbs must pass the leak-down test after reassembly, before you install them.

Thanks. Did all of the above except the leak-down test. Thanks for pointing that out.
