final update , installed carb kit, found fuel filter fuzz under smaller welsh plug and some debri in pump side -I managed to install metering lever wrong first time even with excellent instructions - fired it up ran ok-ish but wouldn't restart without choking , took carb off and inspect metering lever , it was flush with raised bosses but not read to raise needle , so I readjusted till top part of metering lever till level with bosses and lower part of ml ready to touch and raise needle -re- install carb and it runs good and restarts without choke , even stuck in some larch -seems maybe a lil rich on high- but the fuel cap seal is leaking , Ill wait till after making a seal to adjust further -very pleased with all the help here -much appreciated to all -
