Put it out here Apologize if it has already been discussed
I am going down on jets for this season if I recall right I have 2 up on pilot one on main .and dont remember the needle ill take them out soon
I have noticed that the idle adjusting screw slots are not pointing the same
the right is at ca 10:30 to 4:30
the left is at 11:30 to 5:30
I have not adjusted --- that is above my pay grade. I have seen it in some manual Clymer or so that those should not normally be touched But is this something seen before uneven idle screw setting and if so why ?
I have experienced that one cylinder is easier to start than the other left is better.
I have it to rich but is has run without vibrations excellent even .Not perfect on top but in the middle it is perfect.
Always had black plugs mostly because of weak spark those are on the darker side and plugs on the older side
But engine was rebuilt 2 years ago with some adjustment on the crank and new bearing so the vibration problem can have been altered to the better
That is the down jetting reason At the last runs of the season I sometimes had rough running at low rpm in town but I believe I had an air-leak .
But did not put the effort in to fix it since the carburetors was coming out.
Stock intake
Exhaust slightly more open about 10 -15 %
I would appreciate comments on he Idle screw and recommendations on Jetting does Manual stock settings sound good which i am pondering to try.
Or perhaps stock + one up on Pilot .Since I have had good experience with slightly richer.
And know one that went to lean and pretty much scrapped the motor.
