I too dont know much about the engines. Now ofcouse I know basic and some advanced engine rebuilding, but Ive always been working with briggs..
I hope somebody can help us both on some details..maybe someone knows a link to some videos?
I do like the "carlike" filters and the carbs seem easy enough...mine also have a push-pull oil drain plug..I like the idea, but i may remove it.
I got them free, and I know why, I removed the spark plug to check for any compression, and they have a deep plug pocket, so I slide a 2 foot rod into the hole
and I ended up pushing the piston back...and the crank had no movement....turned the flywheel by hand...no movement on the rod...and sure enough the flywheel came to abrupt stop..
So, for sure both engines have broke connecting rod assemblies..
So I will be pulling them apart soon...Please post with some guidance and IF anyone has some warnings or tips prior too...let me know!
