I've got a Johnson 150 (J150NXEDB) that we just put a new powerhead in. We followed every detail per the factory service manual and now we're trying to set the timing. We're following the instructions about the link and sync and trying to set the timing using an optical timing light; TDC was located using a piston stop and setting the pointer. However, when we turn the motor over (base held back to the stop and adjustment tabs all the way forward), the base timing is around TDC; when we advance to full advance using the roller wheel it's close to 30 BTDC. Any adjustments on the tabs make it worse. I can only imagine the quickstart is still engaged, even though we've turned the motor over for more than 10 seconds and the temp sensor white/black wire is grounded.
I've read posts about disconnecting the yellow/red wire from the power pack, but if I disconnect it from the solenoid, I can't turn the motor over. If I try to disconnect it from the power pack it's part of a bundle that's clips in. I'm not sure how to disconnect it there. Is this part necessary? Many people don't mention it when checking timing, but others do.
Any suggestions would be appreciated. Thanks
