Black Specks I could deal with but this is a whooooole lot more that specks. If you hold your hand behind the pipe at full throttle it will completely blacken your palm in 10 seconds and no matter what you try to remove it with it will take days just to wear off. It has gotten a BIT better over time ( 5+ gals now ) but not much. Tried several different oils ( including the recommended Mobil ) at different mixtures and have finally settled on Amsoil @ 50:1 the same as my other gassers.

My history with gas engines has been poor. My first gasser a Quadra 42 has been sitting in a box for 15 years because it is too heavy and underpowered for the type of planes I fly. I have a Brison 2.4 which gave me 4 years of fits and after 2 trips to Texas at a cost of about $400.00 Cdn. I finally in desperation sent it to C & H ignitions and they got it working for me, it works well now. Now the problems I'm having with the MVVS. I have a NIB Taurus 52 that I hope will be my Saviour. If not I'm done with gas.

Sorry to bend an ear but I'm a bit frustrated. Glow engines on the other hand other than a Magnum .45 I had 20 years ago have been without incident.
