Hi everyone. I was hoping someone could shed some light on this for me. I was given a 1973 9.5hp johnson and the first thing i did was run a compression check on it to see if it was adequate, and by adequate i mean anywhere from 80 to 125psi. I know that is a wide gap but have gotten a pretty wide answer range for these so kinda just stuck with that as a base. Well i ended up with 40 on both cylinders which my gut is telling me is extremely low, but i'm now where close to novice when it comes to outboards so here i am. It fires up and runs mid to wot fine for about 5 minutes and almost always dies when brought to idle. So am i just turning circles or do you think i should just put it to bed. Thanks in advance!
