So I bought this thing a few weeks ago with the engine out of it, half way apart and rusty. I tore it all apart, cleaned it out, put it back together and re-installed it. She'll fire right up and run for a few seconds on starter fluid, but for the life of me I can't get fuel to flow out of the carbs. I'm getting 1.5 to 2 lbs fuel pressure while it cranks over, I've had the carbs apart and they weren't dirty or clogged up. The float bowls are filling up with fuel but no fuel is drawn out of the secondary venturi when it cranks over. I've got 100 psi compression out of all three cylinders. I'm an auto mechanic and this is my first time messing with water craft stuff but I believe I got everything back together and hooked up correctly. Any input would be appreciated, thanks.
