Need grizz 600 Carb info PLEASE!!!!

So i’ve fixed my electrical issues and now moving onto the carb,
i have cleaned it up – it did have a rebuild kit put in it about 300 kms ago.

Right now it doesn’t want to start and i do get good spark.

It does sort of try to start for like anywhere from 1 -3 seconds, but just can’t get it even to an idle yet.

I have heard a few ppl talk about the idle screw thingy that sits at the bottom of the carb….i’ve read anywhere from 2.5 to 3.5 turns out……does this mean screw it in all the way so that it sticks out into the air intake and then turn it back out?

The other thing i’ve heard is that you can try to adjust the main needle jet position, there are 5 little slots and right now it’s in the middle slot, so i’ve read that if you move it in one direction or the other that it could improve things, is this true??

There was a thread that someone had posted on how to put in a carb rebuild kit…but i couldn’t find it, can anyone help me find it.

Sorry for the long post, any help would be great, I WANNA GET THIS OLD GIRL UP AND BACK TO WORKING IN THE YARD!!!!!!!
