RAN BEAUTIFUL THE WHOLE TIME!!! Was running between 245-260. I only barely tuned it with the LSN and turn it in a half turn more because it would load up a little at idle and it was perfect! Idled forever and tons of power. Thanks for the info guys! NO CARB PROBLEMS HERE.
Nice one vnmsgt. Those settings seem to solve most problems !!
I don't think the needle thing is really that much of an issue. Itīs more that these Go engines tune different from most other engines, and if thatīs the case, so be it. As long as the engine runs hard when you have the tune correct, you canīt ask for more than that.
The needles are very sensitive, especially the LSN, but once you get it right - bingo !! A lot of the guys running Goīs down here have the long LSN needles and we donīt seem to have too many problems. We have several really good tuners in our group that have the tuning sorted and the rest of us feed off their input.
I have just changed to a fuel with 5% less oil content than what I was previously running and found I needed to lean both needles just a little. LSN is now in just a hair over 2 3/4 and I leaned the HSN about 2 hours.
You have to allow a bit of leaway on those base settings to allow for fuel, pipe etc, but if you use the flush HSN / 2.5 in LSN as a starting point you are never far off it would seem.
