I ecomodded the pressure washer. I found a hack that allows the UT2 Honda digital ignition to give 4 to 6 degrees more timing. Simply back the coil all the way away from the flywheel. I got 4 degrees of timing at 3,800rpm. Also this gave me at least an additional half horsepower as the throttle was held wide open and the engine hovering at 3,800rpm. With the timing advanced in was able to hit 4,100rpm holding thethrottle wide open.
Next mod I'm going to install a 2 or 4 degree timing advance key. I'll probably do a 4 degree key and I can play with the UT2 coil to fine tune timing.
A "4 degree key" really gives 6 or 7 degrees plus 4 degrees of digital ignition should give me about 10 degrees of total advance. Might need to back that off a hair.
Stock timing is about 20 to 22 degrees. Moving the UT2 gave me a confirmed 4 degrees and the advance key has given about another 8 degrees.
