I tried different engine last week (Novarossi, Picco, Os) but I had some problem with the glow plug.

The spire of the glow plug seemed "squezzed". Why?
I put a new glow plug, after 20 minutes... the same. I tried other brand the same... same problem.

I tried differents glow plugs. Picco, Novarossi, Os, FX. What's the best?

Which kind of glow plug do you use for 1/8 on-road?

Waiting your answer
