Question
Hello,  there are two timing marks on the flywheel a T and a F can you tell me which one to use to set the timing and what dose the F stand for.Thanks

Answer
Jim, the T mark is for TDC Top Dead Center meaning the piston is at the top of the stroke. F mark is the FIRING mark, meaning that is where the ignition timing should be at idle. Usually on most Hondas the F mark is either 5 or 10 degrees before TDC.
