Thanks bubbagates!

OD type F plugs are mainly for 4-stroke engines so they are hotter since a 4 stroke fires every other rotation of the crank.
Yes i am aware of it. It is clearly stated on the package. However it might not be the best choice since the plug is longer in length (for specific 4 stroke engine manufacturing) and the combustion might not happen perfectly on the top of cylinder. I recall it is suggested for inverted mountings, where the oil could simply "drown" the plug.

As far as fuel delivery, I'm not sure on the Moki, but you may need to put a pump on this one but that depends on something else which I will address at the end of this post. What you did as far as fuel lines works very well for the OS160 but the Moki is even bigger in CC amounts (read that as volume) so you may have no choice. You may have been better off with the standard Slimline instead of the oversize can version. The standard one would have given you more pressure.
My fault. I wanted a muffler with smoke predisposition. However, Slimline has only the "Large Volume" mufflers for Mokis. Bisson muffler might be better, dunno.
Not sure for the pump. I'll leave it as a last resort. Don't want to get the plane heavier than this.

Also, if you have a fueler valve installed (Dubro or Slimline), the type that you plug a probe into to fill the tank, remove it as well as you could be getting air as those are well known to leak and do a three line system with a fuel dot.
I bought one, but never installed. I didn't like the idea of punching another hole in the airframe.
Now i'll definitely leave it for a future plane.

I do not believe changing plug is going to do a thing in this case, it's a fuel delivery problem.
Yep. But at least it will help me getting the engine started more easily and the 2V starter plug less attached.
