Re: No compression
most likely carbon under the valves..pretty common condition....hand rotate the engine ,when each valve is at its highest.a tooth brush type wire brush with a little kerosene or diesel fuel scrub the seats in the block and each troubled valve..clean them up and ck compression again..if the compression improves,you might get away with lapping the valves....poor fuel,,short trips doesnt heat the engine enough to burn off the carbon..on and on!
