I went to a parking lot to get some basic tune and got into strange problems.

Idle is OK, acceleration is great but engine started to stall after like 1second on full throttle like it is very lean on the top. started to richen it up a bit and ended up with HSN one full turn from flush. with this engine seems ok.
LSN is at stock setting, idle is just a bit more open. (1/8 turn)

this is quite strange setting as my previous engine was like one turn in from flush (half turn from stock setting)

is it normal?

I have same setup as before. 30% OD, P5, 9901 pipe (I wasn't able to tune it with 2041)
