Your motor is a 1975.I don't understand your question.Are you saying it's not cranking strong with the starter while plugs are in?Is your battery fully charged?Starter connections clean and tight?
battery is fully charged. posts are clean and tight. under compression with the plugs in the starter barely turns it over. could it be timing or starter problems
Probrobly the starter, but before ya send it out, crank motor for a couple of seconds and feel the battery cables near the battery and near the motor. If their fairly warm or hot its time for replacement.
"Posts are clean and tight". Good.<br /><br />What about other connections? The negative cable connection to the block is a constant threat on that engine, because it is usually bolted to the steel bypass cover.<br /><br />Put a voltmeter from the starter hot terminal to the negative battery post when cranking. If it reads near 12volts you have a starter problem, If it reads below 9volts you have an electrical connection problem.<br /><br />Good luck.
