Default Re: Compression Test

Once it starts the compression numbers should come up once all the parts get to functioning. An engine that sits for a long time will lose compression and the valves will not work right. Before I tore into it I would make sure it is torqued, put some MMO or something in the spark plug holes then just crank it over and over until it fires. If it ran before and the fuel system is working then it will eventually fire. I have run a battery down almost getting one to start but give it a rest as the starter and cables get hot while cranking.
