I aquired a deluxe 4 E4RDHCUD B1382644.<br /><br /> The decal at the fuel interface reads 100:1 just want to qualify that is correct. <br /><br />Then of course can you recomend a champion plug #. <br />The manual is on its way but still a few days out.<br />Nice litte motor starts on the first pull, $300.00 well invested I believe.
