86 25hp merc manual-recently replaced both coils, water pump and plugs. now runs great until I put the engine cover on then then starts missing at mid throttle, remove hood then runs 100%. adjusted carb idle/mixture. What am I overlooking? thankyou

Thankyou Laddies for the reply and info. I won't get back to the motor until this weekend. I will let you know what I find. Thanks again

Laddie-I finally got back to this motor and the arcing and lower plug wire were the problems. Up and running again. Thankyou
