sceondary compression

[@Rein_Ciarfella]

22/03/22 I've been teaching myself small engine work for the past nine months and am compiling a complete diagnostic process worksheet so I do things in the right order, avoid testing when I don't need to and make sure I don't miss anything. I've searched for and found every video Joe Pace has posted in an effort to assemble all the diagnostic information available for the "Advanced Sequential Troubleshooting Worksheet" (which was mentioned in every video but which I cannot find anywhere). I have seen six parts - F (two parts), G, L, I and O plus the Block Off Plate section but have not found Section H or a copy of the entire worksheet. If anyone has more information or even just a list of what's on section H I'd be most grateful. I'm posting this on every one of the above sections in hopes I'll finally get the attention of someone from Husqvarna like a servicing dealer who is willing to share that information.

i use 12 bar compression for road race 115-125cc engine, still effective until 11 bar, so when we get until more than 12, we lowering the compression ratio, make bigger room for explosion, make more energy. sometimes until 5.85:1 with 11.5 bar, the lower compression ratio with high compression gauge number, more power you will get..

145 psi is a 9.8 comp ratio. I thought these small engines where about 8 max. Unless being a high end engine it is built to a higher rating.

So can we assume that you could use open ended adaptors but just add 55psi to your reading.

PLEAS CAN YOU TELL ME,CAN I USE HOSE 14 mm standard reach thread FOR MEASURE COMPRESSION ON THE SMALL ENGINE(LAWNMOWER) WHICH HAS SPARK PLUG 14MM LONG REACH THREAD,CANT IT BE DONE?DATA WILL BE ACCURATE? OR I MUST HAVE A HOSE 14MM LONG REACH THREAD? THANKS&REGARDS!
