I took my fj40 out for the first time yesterday, and noticed only one problem. As I was climbing a 75 degrre 4ft high berm at this cunstruction site and I could get up it, but every time I made it up to the top, the engine would stall out. I was wondering if this was from the angle of the truck and it not getting any fuel or if there would be any underlying issues. I have a stock 2f save for a weber 38mm carb. on the road she performs great and I really have not noticed any other problems.
