Have had the valves adjusted in the past by the shop. I am now tackling that myself. I gained the covers turn off the intakes and also exhaust. On height dead center, need to the piston be up in the direction of the optimal of the head? ( i can inspect with a straw ). Additionally do you leaving it at TDC and readjust the 2 intakes climate the exhausts without moving the piston? one more question. Looks come be difficult to acquire a feeler gauge in the exhaust. Perform you need to bend/flex castle or to buy a feeler gauge v a 90 level bend? do you placed in the feeler gauge, then tighten under the nut v the gauge in and then remove after tightening? ANy assist woiuld be lot appreciated. Don"t desire to chaos up my first try.
