Just to let everyone know what I think I learned in the past three days, 3 weeks, & 3 months of working on this motor.<br />#1 I think it is easy but it took me these three days to understand the book. OK here is what I did.<br />Remember I am doing this in my basement without the motor running.<br />1. Hooked up remote control cables. Biggest reason for not understanding how to do this.<br />2 Put shift lever in neutral position.<br />3. Adjusted trigger coil to approximately middle of bracket. Spark advance arm is about in the middle of travel.<br />4. Checked timing with timing light. 2 dots appeared in the window just like the book said it would.<br />5. Moved throttle advance on remote control unit all the way forward to simulate maximum throttle.<br />6. Checked again with timing light and solid white line appeared in the window just like the book said it would. It is off a little but I assume this is because I am not runing the engine.<br />Don't know who the guy is that said. "Read the Book" but that is what I did until I understood what I was reading. <br />Thanks again for all your help.<br />roger2
