help my 383
 
did a compression test on my 383. engine at 200deg. all plugs out. when i turn the key the gauge is jumpy and moves really guick. i can see it goes up to 160 ish but its to fast to deterimine a real number. needle goes up rapidly then down. it doesnt build pressure or slowy move and stay at a reading. its like this on all cylinders. any comments?? doing a leak down tomorrow.

need more info.

why are you doing a compression check? whats wrong with it?

Sounds like the valve in the tester is leaking back! It should hold pressure on each piston stroke till you manually release it!

Stop lugging the motor to 1k RPM! Drop a gear and run second or change the rear end gears.

bk2life-- im consuming oil. wet side pipes but not very much smoke at all. spark plugs arenot foul with oil.

jester---i figured the tester was bad. wanted to see if anyone had that same issue.

Try changing the schrader valve in the gauge, just like in a tire valve stem, same tool same part. ;)

Block the carb wide open for the test- do NOT forget to return it before starting! :pain:
