My Nitro RC aircraft engine won't start

by James TTupper

My Nitro engine for my RC plane won't start, the fuel seems to be going into the carb and into the chamber and when I spin the prop it drags more through but won't seem to catch.
It sort of ignites but then stops instantly. I have noticed that the prop is VERY stiff at a certain part of the cycle, so much so that I require quite a bit of force to turn it round. Any advice would be of great help. Thanks.

Hi James - if the prop is that hard to turn over then it sounds like the engine is flooding, in other words too much fuel is entering the chamber. Either you're over-priming it or the mixture needle valve is open too much. Which engine have you got, and which glow plug are you using? Is it a new engine or second hand?

It is a new engine, a GP-42.
