ok first i wanna start by saying i did a search for this and cant find enough info to go off of... i finally got some new piston rings in my ytm and got it back together.... ive double checked my timing, if im even doing it right... i start with the piston at T.D.C and line up the arrows..... she will start but in my own opinion the timing seems to be alittle off....but she runs... any tips or tricks on valve adjustments?? do i check em at top dead center also?? something like.... intake = .05-.09 mm... exhaust = .11-.15 mm .... i should also say before i double checked my timing... i figured id double check my carb....as its been sitting in a box for 2+ years... i didnt tear it down but just gave it it a good cleaning....clean....it just doesnt seem to rip like i think it should... although i havent taken it on a hot lap yet...i still gotta fab up some new engine stay brackets...as mine were lost in the last move... any tips or tricks...?? any input or insight would be appriciated. ....also ill get some more pix up after the ole lady finds the SD card for our camera... Thanks guys.. :wondering :wondering
