Default Nitro Hammer Engine Problem Solution, Please!

Hello, RC guys!

I have a Nitro Hammer by Hobbico Aqua Craft. It used to run bery well. But one day it stalled on the lake while running. I retrived it from the lake.

After that, it continuously dies at the full throttle, while the engine starts well. I checked air leaking, the fuel tube, the fuel tank, the muffler & the connerctor, but they are OK.

Also I disassembled the engine, but everything looks fine. And I richened the high needle. But still the engine continuously dies at full throttle.

I really cannot figure out the reason of this continuous stalling problem at full throttle.

Could you give me any ideas, please? This problem is so frustrating. Your advices will be appreciated.

Thank you so much for your attention.

Thank you very much for your response.

Well, in fact, I changed the glow plug and checked tubing, pressure, and the throttle servo. But still the engine dies at the full throttle.

By the way, what does "adjusting LSN" mean?

Once again, thank you for your attention.

sorry for that, means Low Speed Needle, it is a screw head like located in the throttle linkage of the engine carb, need a flat screwdriver to adjust, i think 2-2.5 turns from close.

check ialso the 2 bolts holding the header is tight...or maybe a bad fuel.
