So I snuck away tonight and spent 2.5 hrs. with this motor.........100% no go. Just for the heck of it I set the needles to 3.5 HSN and 4.5 LSN and ran it. Really bad lean bog, and ran so-so on top once you got it rolling and got some fuel in it. So I tried to keep richening the top just to see how far I could go with it to get rid of the bog. So the HSN is 4.5 out now just to experiment and the low end is almost there and but it is too rich on top and will not stay running. If it is on the starter box and you blip the throttle it will barely bog, then settle into a nice idle for 2 seconds then the rpm will pick up and just shut off after 8 seconds at 4.5 and 3.5 on the needles...... Runs out of fuel, lean! Really erratic idle.
So I ended up at 5.25 on the LSN, and 3 on the HSN. Only way I could get any kind of snappiness and crispness out of it, running 280 to 300 at these settings, but it is really crisp will idle nice and smooth and run all day. I guess I am not going to worry what one of these motors "should" come close to running at and just run and race it there. I put the OS Speed in just to check with the same pipe, same everything and no problems at all. I just hate that I can get 8:30 to 9:00 minutes out of it at these settings. Tried all different pipes to no avail!!!!!!! Spray motor clean all on the front bearing while it is running and has "zero" effect on the idle.
I am going to replace the front bearing in it just to be safe and run it where it runs best!!!!!!!!
