Default Anti-siphon valve?

I was reading the owner's manual - trying to figure out why my engine is losing power. Could it be the anti-siphon valve? Anyone know where this is located? The manual is very vague. Is this a do-it-yourself replacement?

I really hope we can get on the water today!

Thanks

I always thought the anti-siphon valva was the 90 degree elbow coming out of the top of the fuel tank that the fuel line is connected to.
Looks simple enough to change.
I would try tightening the clamps on the fuel line just in case you are sucking any air.
Also check the fuel line for any cracks or pin holes, remember a suction line will not show a leak.
On another note you could have some water in your fuel.

actually...could be the fuel vent...if that's clogged..then you will loose fuel pressure and pwr....check to make sure some wasp or mud dobber didn't try to build a nest in it..

Anti-siphon valve is typicall installed in the elbow on the top of the tank -- and the fuel hose is connected to the barb end of th AS valve.

Sorry I did not post up sooner. Turned out to be the cap and rotor, plugs also looked bad. I did not expect these as I paid big money for the shop to go through the motor before I took possession. Oh well, running fine now.
