dditch,

Make sure you have the timing set proper on the engine. Look in the back plate of the engine and you will see the dot on the crank by the bearing journel. Line that up with the center seem of the engine then look at the cam gear and make sure the dot on the cam is to the top. Make sure the engine and gaskets are all back together right and then reset all needles. The high end needle should be 2 turns out and the low in needle should be 1.5 turns out from closed. The regulator screw should be flush with the regulator housing. Start the engine and let it warm up before going to full throttle. Once you get to full throttle adjust the top end to peak RPM and then back it off to a slite rich setting. Once the high end is adjusted start lowering the throttle to an idle till you get to around 2000 RPM. Let the engine sit there and listen and if the engine speeds up at idle then screw in the idle about a 1/4 turn at a time till you get the idle to hold. If the engine gets to 2000 RPMs and then starts to slow and want to quit running the turn the idle screw counterclockwise to lean it some and about a 1/4 turn at the time till it's right. Each time you make an adjustment go to full throttle and then back down. If you go to full throttle and the engine sounds like it's straining or if you know what predetination sound like you need to richen the regulator by turning it out. That gives it more fuel and if it's spitting and sputtering going up to full throttle then screw the reg. screw in to lean. Once you have the engine where it will idle ok and also transition good then you can go back to the idle and fine tune it some more. I hope this helps and once this thing is set you can forget it. Remeber the regulator screw controls the transition, in for lean and out for rich.
