Default RE: need help breaking in new engine

Quick note about cordless drills for starting motors.

There are 2 basic types of cordless drill... Those that allow you to tighten and loosen the drill chuck with one hand (the shaft locks when you try to turn the chuck), and those that require 2 hands (the shaft rotates when you try to turn the chuck). THose with the one-handed chucks will lock if the engine trys to turn the chuck faster than the drill is spinning. Found this out when trying to start my Norvel 061 with the cordless. Worked fine with the corded drill, but couldn't be done with teh cordless at the same speed. Your engine is a clone of the Norvel.

That said, these tiny engines are very picky about the needle setting when starting. If when you are spinning it, there is fuel coming out the muffler, but no sign of firing, it's too rich. Close the needle valve and turn it till it burns out the charge. Then try again, with less rich setting. Close about 1/2 turn at a time until you find something close. Typically, on muffler pressure, they end up being about 1.5 turns out, give or take half a turn.

Also, be sure that before each time you hit it with the starter, you flip it by hand (no glow) a few times to be sure it's not flooded (hydro-locked). If it is it will offer extreme resistance at compression. Forcing it past, or using the starter when this is the case will bend the rod or break the crank. Not a hard thing to do on these tiny guys.

Good luck,
