Buying a timing light today and going to time my motor. The manual says all 3 cyl except 70hp is 2 degrees atdc, is this correct and is putting it in a barrel, in forward the same as tying it to the dock?
We dont worry too much about actual idle timing. That will vary with set up. It has to do with backpressure. Whatever the book calls for is a good starting point but your actual (best idling) timing may be different.<br /><br />WOT timing is a different story. It has to be varified under a load. No matter what method you use to set the initial. Setting top end timing in a barrel can be tricky at best.
I'll do the top end in the water with the brother in law driving....got me a timing light today <br />As long as it's close to spec use your ears for idle timing, got it.<br />Should I trust the pointer for tdc? Do they move if hit or should I borrow a dial indicator?<br />Thanks for the help<br />Matt
Its always a good idea to set the pointer first.<br /><br />I would suggest checking the top timing while on the trailer backed into the water so the motor has a load on it at 5500. <br /><br />Hanging off the back while under way can be a bit more exciting than you want it to be.
