I don’t have a scope.It did sound like some air movement around the valves also But mostly out of the dipstick. The plugs got slightly oil running it just for a couple minutes so I’m guess rings or piston.
Test guage was building virtually no pressure with almost 100 psi going in.Not sure about the mowers past. Guy just brought it by and asked me to check it. Put new plugs in and they were getting oily immediately.
Runs perfectly for couple minutes and then starts pouring white smoke.
Think that may be the case here. Springs push down same amount on both exhaust and intake. Valve lash was VERY loose so I may have gotten lucky and just bent a push rod. Thanks for the response!
Working on a v twin briggs(44t977 -0015g1) with a bent intake push rod. The valve guide is pushed (has a spring,rubber seal on top)out slightly higher than the exhaust guide. Can anyone tell me how much the guides should stick out of the head?
Thinking about readjusting and peening valve guide.
