sled bogs down

[76liquidfire]

hi
i have a 1976 liquidfire 440 i took it out for a ride today
but it would not stay runing soon as i would give it more gas it would bog down and then die. i replaceed the fuel line a week a go but did not run it after i replaced that
i got a fuel shut off from a brigs and stration engine but i think it does not flow fuel thew it too keep it runing
any help would be great
thanks

try removing the shut off valve, and make sure your carbs are spotless, sounds like your barbs could have a plugges jet.
