Hey Carl…Question for you. I never added any petro to and from Marshall pulling those long hills. The temps you see in the video are just about where they ran most of the way. They would drop going down the long hills and climb to around 1100 up the long pulls. Would run around 950 on the flat running around 70. You can feel when it no longer helps to push any harder on the gas pedal. It seems like there is a point it is doing all it can do no matter how much vacuum you pull on the hopper. It seems like the cross over temp maxes out around 1100 degrees no matter how long I pull on the unit, or how much I push on the gas after it reaches the point that it really don’t help to push any harder. My question is this…I am running the 6 inch choke and I’m thinking that with the 6 inch choke it is probably producing the max amount of gas it can possibly make and limits the power at increased RPM range. However is it also limiting the temperature of the discharge to around the 1100 range which is where it seems to max out at? I’m almost to think I can’t over pull the unit with the 6 inch choke as long and hard as I was pulling it up those long hills one right after the other… Never seemed to loose power at the top like it had burned to deep in the char and was always ready to start the climb up the next. Would a 7 inch or larger choke have given me more power up the long hauls up hill, but also would it have let the temps continue to rise to a point it would not be safe on the unit.? I’m thinking with my driving habits I may be better off with the 6 inch choke for that reason. And with the good dry wood I was plenty happy with the power pulling those many Arkansas and Missouri hills…LOL It is absolutely amazing the difference of nice dry wood can make on performance of the unit. Thanks again to Carl and Richard for bringing me enough wood to make it home.
