Re: Won't go fast under Load!!! HELP
Wouldn't the rotor move as soon as the engine is started? complete long block is new including cams. Not sure about the weights. Where is the breaker plate?
With the dizzy cap off you should be able to rotate the rotor by hand. The rotation is your timing advance movement. The dizzy shaft (rotor sits on it) goes thru the breaker plate, which is where your points or electronic pickup are mounted.
Download the manual for your engine from the adults only section. It's bound to have an exploded view of the dizzy.
If the tech checked timing at idle, its a worthless measurement. Timing should be measured at full advance, which should be in by 3000rpm on a marine engine. Timing should be 34-36* (more than 36* you take a chance on putting a giant hole in the top of a piston), I usually set mine at 35* to be safe. Less than 34* and you'll lose rpms.
If the tech set the timing 10* at idle, and you have 20* advance in the dizzy, you'll get 30* total advance. 4-6* will make a huge difference. It's very helpful to know the actual advance your dizzy is capable of.
