Question???-- are you taking ALL the spark plugs out of the engine and removing the push rods from the cylinder being tested????--we have used 12V/16V/24V starters to makes no difference- we get pumped regularly and never have had any problems as long as you correct for engine temp---- if there ever is a problem with one cylinder which RARELY EVER happens we move along to another cylinder still pumps accurately tho---we know exactly how big our engine is no guesses there--- never had to pull a head in the last 30 years--FED387
