hi all,
is the proper fuel for the 110 still min. 90 octane. no ethanol preferable but ok. last choice is avgas 100 low lead.
thanks, bob noffs

"Thanks. How about the Turbo 195 - does it lean with altitude like the 130?

"Only if you would like to do so. The engine will start and warm up on its own."
"Thanks! I have another newbie question. Since the Viking engine is built to automotive tolerances regarding piston to cylinder clearance - is preheating required in cold weather?"
"Hi Bob. Yes you are right. The manual says maximum of 15% but all auto gas here in Brazil has 25% or 27% ethanol. Since I am monitoring closely and I had no issues with 90 hours of flight and it is a very clean fuel, the only concern would be the…"
"thanks jose. isn't 25% a little high for this engine?"
"Hi Bob. My 110 engine has 90hs. I use auto gasoline here in Brazil with 25% ethanol. It has 95 octane. I used 100 LL only once just to test. Saw no noticable difference."
"Chane, sorry, I misread your name.
I did some experiments with the coil spring, compressed it with a hydraulic press on a scale until I didn't dare compress any more.

"Thanks Eric,
I started my 801 in 2008. I’m getting close to finishing it now and my original bungee is sagging. I would rather change it for a spring than buy a bungee that I’ll have to change every year. I just wanted to make sure the Viking…"

"Hi Chuck. Yes, I put a steel bungee on my 801. Haven't flown it yet, but did a lot of taxiing and it seemed to work fine. Compresses about an inch, and has another 3 inches of travel.
The inner diameter of the tube seemed to be a little tight and…"

"Is anyone flying an 801 with the steel bungee? "
"Yes, it does that and there is no altitude limit for this"
I'm new to this forum and new to Viking Engines. I'm early in my research. My question is: Does a Viking 130 engine reduce the fuel rate automatically through the ECU as altitude increases - to lean out the mixture? If so, is there an altitude limit…
