Told you all I would make a movie so here it is. Timing is at around 16.5* and it was 18f this morning.

As a reference, heres how it started with the stock 13.5* timing at -2f.

That's kinda interesting. The biodiesel has higher cetane so it starts better. I notice a big difference when trying to start with #2 and B20. Mike has endless info on this fact. More cetane, more readily it ignites but also less mileage. That is why 2 stroke may get you more mileage, it lowers cetane giving you a longer burn time. The longer it burns the longer it is producing power. I have not noted any decent mileage with straight B20, if I do run it, it is a couple gallons of it with the rest of the tank of #2 so I can get all the lube without sacrificing mileage.

in oklahoma i don't ever see bio...what are the price difference between them(if any)?most places around here still sell #2

The place with the B20 is about the only place I know of in a 50 mile radius. It is consistently 10-15 cents more than #2. Definitely weird since E85 is so much cheaper.

different crops.
