Default LST XXL Breakin Problems

Hi, Iam new with monster trucks, just bought an LST XXL 2 days ago, I tried to breakin this morning and I found out that everytime i remove the glow igniter the engine shuts down, I reset the needles to the factory settings and its still the same.

I am at Malaysia and temperature here is around 29 to 32 deg C. Do I need to change my needles? I am using a 25% Nitro Fuel.

Also, I find it difficult to remove the receiver battery because the cable conenctor at the other end cant fit the space where they inserted the cable from below, very small opening an I am afraid that this design would damage the wire insulator when the engine is hot..

Help please.

For the engine problem - it sounds like you need a new glow plug.

Anything i need to do with the needles, its at factory default now.

Glow plugs can go bad, even if they still glow. (The coil can get a glaze on it, preventing heat build up and dissipation.)
Replace it, and lean out the factory settings 1/2 turn on both needles.

try letting the engine warm up, replace the glow plug and make sure there are no air leaks

If it runs with the igniter on and dies when you remove it is because the engine is too rich. The glow plug remains lit between cycles because after combustion, the conditions are perfect for the heat to stay in the plug. Too much fuel and the plug will be blown out by the abundance of fuel. losi engines are known to be super rich when new.

I would go in a trun on the high speed needle, get the engine up to temp and then bring it to a safe tempreture by truning out the high speed needle if necessary. Dont play with the low end needle untill you get the high one set.
