What is the shortest acceptable compression on one of these engines, and also what should be optimum? THANKS!
What is the shortest acceptable compression on among these engines, and also what need to be optimum? THANKS!
On engines with compression release feature,if the valve clearances space correct,it"s only going to be approximately between 50-75 psi.If it"s an ext than that,chk the valve lash due to the fact that if the valve v the release on it has too lot clearance,the movement of the relax is taken increase by the excessive clearance.A cylinder leakdown check is the most accurate because it tells you real quick the problem of the peak end,and pinpoints the exact problem source.Whenever possable,that"s the test I prefer to walk by.Steve

ns agree through the over and it is not argued by briggs to use a compression tester together they execute not market compression specs on your engines. They desire you to use a leak down tester and or a manometer to test the internal problem of the engine.

I have run compression tests on many Briggs V-Twins v properly adjusted valves, the readings are generally in the 120 -135lbs range, 50 - 75 lbs is low for an OHV engine, i don"t think Briggs made any kind of 26 hp engines that were the opposed twins so there is no the model variety of your engine ns am making the assumption that the is a V-Twin OHV engine.
