I decided to screw up my timing yesterday with a timing light. I misread and thought the marks on the crank pulley needed to be inline with the seam on the crank case. Now it won't start and I get lots of pops and hissing. The plugs are greasy. It ran fine yesterday until I got involved... Here's what I am doing. Electric on 1st cylinder set with depth gauge to 4mm BTDC. (Engine rotated clockwise at the fan until TDC is reached, then reversed 4mm. Maybe I need to take it back further and then forward to 4mm BTDC and I am introducing backlash?) Test light attached between both terminals on 1 cylinder's ignition coil. Test light is on. Pick up base plate adjusted until light turns off. (Note, at this point, my fuel solenoid which is wired to positive post of ignition coil and the grounding bolt of the ignition coil mounting bracket, clicks.) Procedure is repeated for the 2nd cylinder but set to 3mm BTDC. I found on pappenforum.de a post where it was instructed to set the testlight up to the ignition coils terminals and adjust plate until light goes out. Due to the two stroke cycle, for one complete revolution the light is on and for the next it is off. Perhaps I'm doing it backwards? When I put the test lamp between terminal 1 and ground of ignition coil, light stays on for multiple revolutions. Thanks.
