What glow igniter are you using? If you lot are using a power panel (starter, glow igniter all in one, used for planes), it is actually easy to plug that glow igniter into the 12v port and pop a glow plug instantly. Anyone with these panels has done this lol. Just make certain you are only putting a max of 1.5 volts to the glow plug. Likewise, make sure the glow plug is glowing past pulling it out of the engine and checking it.
My next idea was the carb. Are y'all admittedly certain the carb is not chock-full? If you are not 100% sure, accept it off the engine and become through the whole carb to make sure all ports are open without trash in them. I accept seen brand new carbs that had an O-Ring get slightly ripped and that minor slice that came off clogged a port somewhere.
The last thing I tin call back of is make sure yous have new fuel tubing on the buggy and make sure yoru carb and backplate are sealing correctly. The head is another area that you want to make sure is sealed properly. If y'all are looking at the front of the engine, turn the engine counter clockwise and make sure you feel a good *Popular* as it goes past the compression cycle.

I just had to mention the power panel simply in case. I popped 3 plugs in a row once because I plugged into the wrong port lmao. Yea, $21.00 upward in smoke that fast lmao.
Let me know what you detect with the carb. Exist sure to practise this on a white newspaper towel or something and so that you can run across the piddling bits that may fall out. Goose egg worse than non knowing what was causing the issues lol

Other than something clogging the carb... there's very little that can go wrong with a nitro engine. You ensure yous have fuel, air and spark ( or glow in this example ) and that'southward almost information technology. So everything will depend on yous setting the needles properly and that'due south is usually a pretty picky setup to find the right settings for.

Most times manufacturing plant settings go it running. Sus scrofa rich, simply running. Did y'all effort to commencement it after cleaning out the carb? Have you looked inside the backplate to meet if annihilation is clogging the hole in the crank? Likewise, have you lot put your finger over the carb to make sure you can feel a vacuum and also on the frazzle to feel some pressure coming out while cranking? Only tossing ideas at this indicate.

Having to open upward the throttle to 25% ways it is way too rich. 50c is also an indication of being too rich. The fact that it is dying when you remove the glow igniter too tells me information technology'south 1 to rich and 2, yous demand a new glow plug. I tin can upload video of me fighting with one of these engines doing the exact same thing with a 'known expert' plug, but one time I replaced it, it purred similar a kitten.
Start leaning it out until it runs good at idle, bodily idle. If it nonetheless dies, replace the plug.

lean out the low at start. Just know you may need to richen it up later. Nosotros are simply testing to run across if we tin go information technology running.

If this were me, I would toss the manual unless y'all need to follow something for a warranty. If non, bin the manual and do what works. I'yard a firm believer in following the manual to get an engine running (I just put my 2.v to factory specs on the T-Maxx per the manual), only if you are having to become a full plow IN just to become it to idle, so the manual is wrong, you lot have the wrong carb, or something else is going on.
65c is pretty cold, nigh 150F. Nothing to worry about there. 80c is but about 175F, again, nothing to worry nearly. 115c is when I would offset adding fuel dorsum to the engine. Just remember, these things were built for brusque bursts of full throttle, not broad open all the time. WOT all the time volition destroy an engine in no fourth dimension. I raced oval, ask me how I know that lol. One night of racing, one engine lmao. It got expensive.

At that place is actually not that much maintenance on 2 stroke gas engines. Go on the carb clean, make sure the reeds are not gummed up and make sure you have a adept spark plug in it. I want ane, just can't beget ane lol.
