[i have crabs]

i just bought 2 rs250's and both grugled for a few weeks and i spent more time tryin to stop the grugle than to get it to skim nicely they have since stoped on thier own except the odd time when foolin around with the adjustments. ive also been annoyed with the loud sound from the hose thet sucks the air in, i added the little silencers that where on some superskimmers which made a big difference but ive now sold the superskimmers so i gotta make somethin simular to quiet them down
