engine trouble
 

what would stop a nitro engine from starting , ive set the carb back to factory settings and put a new plug in but it wont even fire ,

my glow start is full charged and ive primed the engine but still no joy ,ANY IDEAS ????

Could have a fuel blockage.
Try running a big of white spirit through the carn if so to clean it out.

Sometime you can also get new faulty plugs so try another.

plug and charger are fine tried 3 different plugs in it . its not even trying to start wont fire . carb is not blocked ive tried it

im stumped now

Have you tried the glow plug out of the engine to see if its glowing.

If it is then put it back in and turn the top needle in a quarter of a turn and the bottom needle an 8th.

Look down your carb and hold the carb closed and then wind the tick over screw until you have nearly 1mm (0.8mm) gap and then your tick over is set.

Then give it another try.

i know how to set an engine up been doing this for 10 years now lol . but ive tried everything and it wont even fire it doesnt wanna try and start and its beaten me lol

Keep trying then.......

put some fuel in?
connect starter box correct way?
check its compression if its worn it will struggle
does it spray fuel in a WOT when you blow down the pressure pipe?

you have had the back plate of and made sure the rod is not snapped etc?

ive decided it dead

i had a .12 like that once, turned out in the end that one of the head screws had come loose and head was warped, still felt like it had compression cos it still had pinch, right sod to start but did eventually, just wouldnt tune.
