Carburetors never need to be adjusted once they have been adjusted at the factory UNLESS something is not right with the carb.
If the gas has been in there since last season I suggest you take the bowl off the carb and see if the Ethanol Gas caused the internal parts to rust. Ethanol gas is a very bad idea that the politicians forced on us without considering the affects

After start it backfires, sputters then runs

Hi,when starting bike you put the chock on,remeber this is to make a richer mixture for cold start,so when you start the bike put put the choke off a little bit as it warms up,other wise wat you are doing is couseing it to floud,so again as the bike warms up put the choke off little bit at a time,all the best.

Start snow blower runs for 3 min. and starts to over heat checked oil its ok then stats to shut down like its not geting oil

Why do you say its over heating .Runs for 3 minutes the oil is OK .
Do you understand how the choke works .
bacsicly you prime the mechine in cold condutions 3-4 pumps choke to max throttle at 3 /1/4 .
Start backing off the choke after 3-to4 mins .
The choke shuts the fresh flow down to the engine in cold condutions ware it needs more fuel then air to run.
When the engine starts to get hot it can't run with out fresh air to mix with the gas it won't run anymore because there is to much gas and not enough air
Its simple fool prof will work everytime if you adjust it right

Bike starts but stalls when the choke is shut off

First clean carbs, slow and main Jet also, if 1 (or 2nd) cylinder is not getting enough fuel, it will back fire. 2nd, if you change pipes to a custom opened ones, you have to sync the carbs, if that is not possible (to sync carbs), you have to change slow and main jet 1up.

Backfiring and trouble starting

If you change the exhaust pipes, you have to sync the carbs (if you cant sync them, you have to change the carb jets), usually it is backfiring because the carbs are not in balance.

I have a xr650r it is running fine but it seem

I'd check these things: Is the choke in the "on" or choked position? Is the air filter clean and the air filter inlet not obstructed by something? Also, if the bike has been sitting for more than about 6 months, it is possible that the carburetor needs to be cleaned out and/or the float is stuck.
