Has anyone had this problem with their engine, or does anyone have any suggestions?
Thanks, and hopefully my engine wil idle soon

The piston could be installed the wrong way round! I did this on mine when I took it apart. It doesnt like it!!

There is a cut out at the bottom of the piston on one side. This should be facing the carb so the crank clears the piston at BDC.

Usually, if a piston is installed backwards damage to the piston can occur when the crank hits the non notched side.

The piston is in correctly, but i think the conrad may be backwards. Could this be the problem? Also, does anyone know any ways to take out the conrad and piston? Ive tried using floss to get it out, but it only comes half way and i dont want to wrench it. Everything else is in perfect condition and oiled and smooth. I must have overlooked something...

I am no expert but here we go: you will have to have the sleeve at least half way out, maybe all the way to get the movement required.. Just use a plastic zip tie or the floss. The oil hole in the conrod faces the crank, have this around the wrong way and the conrod bush will not get lube required = very very short life.

Your engine should be too tight and easy to die off. Try to let the idle more higher and use hottest plug. I don't think your engine has any fault. If you can't pull the conrod out now,just don't pull out it by force.

Yeah!Just use #5 pulg. Long body one is more better. Use hottest plug to break-in can solve many problems for you especially small size .12 engine.

If you use 15% nitro,don't forget to take out the brass shim.

Sorry,bro.My bad,...just type wrong word.... have updated it now. please reload.....

Hum...byron 20%..... OK,just take out the brass shim to break-in. And also hottest plug to advance the ignition timing. It will let your engine more easy to keep idling.

Wait....Are you using Normal Plug?

Oh...I see. Forget the shim. Your engine should only have one 0.3mm alu. shim. Try hottest plug.
