I wont go into it but high negative pressures on deceleration happen in the inlet manifold below the throttle butterfly unless its a diesel, are you saying that a honda generator goes through severe deceleration, if it does i would like to know when ,putting oil in a cylinder is the standard test for compression ring failure as it temporally seals the ring
The bottom oil ring is a scraper if fitted and yes a small film does exist on the wall thats why a cross hatch hone is used when finishing a cylinder wall
As for a high performance motor, any motor that uses a small piece of steel to flick oil around inside a motor i would not call high performance engine
some small engines have oil pumps now, and im yet to see a knock sensor on a small honda generator so as you probably know fuel burns at a fixed rate at its stoichiometric rate a lean mixtures burns slower and so does a too rich mixture
Unless a knock sensor is used the timing of a honda is set for 91 ron fuel and if you don't believe me ask honda if they will warrant your engine if you use 98 ron fuel
Honda has a float switch which grounds the primary wire to the coil so the engine will not start if the oil level is too low
And just to let you know i finished my mechanic apprenticeship in 1978 and have been working in the industry ever since
