Well there is no adjustment under the deck. However there is coll LOOKING push button type adjustment where the cltch engagemnet lever is. You pus the button and pull the sheath and it locks in the next seting. Well clutch engaged great for a second then the fancy push button then ajust mech. gave and put the sheath back at the old position. tried this three times it let loose under engagement every time. Any ideas guys, I am glad it is the top of it's range looks like the clutch is in good shape, just need this cable adjuster to hold position!
