Another 8N starting issue

[kspring61]

some history first........
Rebuilt engine, converted to 12volt system, new coil, points, but was using old carb

When I was using the old carb, tractor started all the time, half throttle, choke it and it would fire right up. But I was having issues at full throttle under load and the main mixture screw wasn't having any affect.
I had rebuilt the carb before but the carb bowl was pitted badly in the area of the main mixture needle seat area. So I figured a new carb was in order.

Now to the issue, since putting on the new carb the tractor starts really hard. Any choke and it floods. Eventually with the throttle at idle I can get it to start (well most times). Once started and warmed up it runs great under load. I used the instructions posted on this site to adjust the new carb.

What am I missing on the carb settings? why does it start so hard now and flood so easy?
Or could I have an electrical issue? Like I said once started it runs great, but getting it started is a half hour chore of cranking and hoping it starts at idle. It will fire and sputter but just doesn't start and then one time after cranking it eventually will kick over and start.

Using starter fluid will get it fire up.

Right now it's sitting in my back field because I had it sitting at idle while I was off the tractor and it stopped. Couldn't get it started back up. Same symptoms as above but this time I got frustrated and just left it.

Thanks

if it started acting up right after the new carb ... and fires right up on starter fluid ... its the new carb

use some epoxy / JB weld / to fix the pitting on the old carb ... put it back on and get it running

then tear the new one apart and fix what is wrong with it ....

if it stalled running.. then the key was on.

check points and coil.

you don't mention if this is a front or side mount.. and what coil and/or resistors you are using.

always check sark first.

once you verify good spark... move on to fuel.

post back some info,
