Sounds a little low to me. Check to see if all cylinders measure about the same. ANOTHER ANSWER That would be good for most engines. What you're looking for is any kind of serious fluctuation in the pressure between cylinders. If you're getting 90 psi consistently, you're in good shape.
90 lbs = 40.8 kg
90-100 lbs.
Mine was getting 100. But i dont know how good that is. mines 90
90 to 120 minimum in 3 to 5 revolutions of the motor
~90 lbs/ft. and you should be good.
low compression on 2 cyclenders ALT ANSWER: You have two cylinders swaped on the cap. I did it to mine. Try swaping 1 & 3.
briggs doesn't offer compression ratings for their engines. I will usually pull it 3 to 5 times and look for 90 to 120. anything less is a problem and if it doesn't hold compression there is a problem
It should have 150 PSI per cylinder. If it has a reading of 90 LBS. are less on any given cylinder, Then the engine will idle rough at an idle. / engine miss.You can't have anymore then 15 LBS. difference in any one cylinder.150 LBS per cylinder is a good reading on a fresh are good running engine that's in good shape.You may have only 120,130,140 or 150 LBS. That is your highest reading, And engine will run fine as long as there is no more then a 15 LB. difference in any given cylinder.Hope this answers your question. A 100 or less LBS means the engine is tired / Worn out needs rebuilt.
If your 90 pounds you should be benching 90 pounds, you should be able to bench your own weight An age is typically useful, but 90 lbs. should be the goal (bench your own weight). My cousin is 12 (turning 13 next month) and he weighs 90 lbs, but bench presses 120. I'd say he is very strong for his age and weight but, yeah I'd say 90 lbs. is a good goal to reach.
A stone is 14 lbs, 90 kilos = 198 lbs 14 stone 2 pound.
90 lbs = 40,823,313.3 mg
a lot
