I know it's a common question but which line is the TDC line on the flywheel. According to the old school method of a screwdriver in the plug hole, it would be the far right line. That's where I'm timed at. Bikes been completely rebuild top to bottom. New everything. From valves to timing chain, cylinder, piston rings, plug, carb gone thru. Have to give it a little girl to start it. Back fires while kicking. Once it starts you have to keep the throttle on a little or it dies when it idles down. Sounds just like a timing problem. Pulled the plug and it's pretty black on the end. Not bad though, but rich. Bikes got a 48 pilot 174 main And a 45 leak jet. Don't remember the starter jet size. Third clip down on the needle. Im in the southeast at about 3500ft give or take. Southern Virginia. Any help would be appreciated. Thanks in advance.
