Threadlock or not

[fudded]

Hi

I took the 700 out today, Im determined to get used to it .
After a couple of tanks, I noticed fuel dripping out, on closer inspection the needle valve assembley had come loose.
Should I use threadlock on it to stop this happening again, or will the heat of the engine just melt it ?


regards

There should be no need to use any threadlock on any part of the engine.

No threadlock, just tighten it up

Threadlock can become a lubricant when heated

I think your find that loctite is used as stated in the OS50 Hyper Manual...

NOTE
As the idle mixture control screw is installed with LOCTITE, it may initially feel stiff, and it is suggested
to use a littli larger screwdriver. The screw can be
turned only 90 degrees either way. Do not force to turn
further, or it may break or cause trouble.

Hi Mike

It wasnt the mixture screw, it was the complete needle valve assembly
dunno if this would make a differnce, I have tightened it without threadlock, but i will keep a close check for the next couple of flights.
My main concern would have been melted threadlock getting to the fuel supply whilst flying

Many thanks
