need help breaking in new engine
 

hi all rc's. this is my first plane and i bought a new "AP wasp .061" engine and i've been trying to get it to start. i followed the directions it came with and i have had no luck getting it started. i am useing the right fuel, the tank is in the proper place and the engine is getting fuel. glow plug is heating up, but engine doesn't even sound like it wants to try and start. if anyone knows anything that could help i would love the help. thank you. if anyone has any questions, please feel free to ask.

I bet your using a chicken stick instead of an electric starter.
ok start from scratch
1 remove glow plug and see if there is any fuel in the engine by turning the model upside down, drain that fuel out
2 replace glow plug
3 open throttle all the way place thumb over opening in carb
4 turn prop by hand in the direction of rotation and watch the fuel line from the needle valve to the carb, once fuel gets to the carb one more turn, remove your thumb
5 very important close the throttle. you should have a small cresent opening about 1/16 th wide in the carb opening (trim)
6 put the glow driver on
7 start
run the engine very rich during break in
the best thing to do is go to the local field those guys will help you start and show you safety tips also, like pulling the glow driver from the rear, dont reach over the prop. that by the way will cut you to the bone.
good luck and be safe don't mean to scare you I've never been cut, but i pull the driver from the rear

no i don't use a chicken stick. i made a peace that looks like the end of a starter and i hook it up to my cordless drill. works pretty good. thatnk for the info, i will give it a try.

the problem with the cordless drill is it doesn't give enough initial RPM's to get a new engine going it looks great spinning but the RPM's need to be higher than a drill can give most starters run about 4,000 rpm.
the flooding/or not enough fuel problem-allready addresed.
is your glow driver fully charged.
not often on new engines, but sometimes the glow plug can go bad if the driver has been left on to long,the filiment can burn out.
or just a bad plug,it's rare but does happen.
I don't know the wasp engines they might have particular quirks,but a elec starter from tower is 20$ cheaper than a cordless drill you do need a 12V battery also http://www2.towerhobbies.com/cgi-bin...?&I=LXJC35&P=0

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,
