Wont idle unless i havethe throttle barley turned

Sounds like the linkage spring is not working correctly or was never replaced during rebuild. I would replace that spring as a starting point.

ADD AIR FILTER needs more restrictive intake. Getting a gulp of too much air.

To change the choke cable, you must take the carb off the engine. Remove the air filter and backing plate. Take the nut off the backside of the choke cable and let the cable come out of the bracket that holds it. Make sure the petcock is turned off and disconnect the fuel hose at the carb. Loosen the throttle and idle cable at the handlebar throttle assembly. Pull the carb out of the intake manifold seal. Work the throttle and idle cables out of their positions in the carb. Bring the carb with the choke cable out and away from the engine. Take the choke cable out of the carb with a 14mm open end wrench. Take the plunger and spring off the old cable and swap it to the new cable and reinstall the choke cable. Put the throttle and idle cables back onto the carb, put a new intake manifold seal on the intake manifold and push the carburetor back into the new seal. Put the choke cable in it's bracket and secure the nut. Be careful and do not over tighten the nut as the plastic cable housing will break. Reconnect the fuel line, the vacuum line, and anything else that was taken off. Replace the air filter backing plate and the air cleaner. Readjust the throttle and idle cables making sure that the throttle operates freely and returns when let go on it's own. Never put any kind of lubricant on the choke cable. There is a knurled wheel that you can use to tighten the cable so that it stays where you put it.

Sounds like there could be a problem with the main jet not delivering sufficient fuel for normal running. Clean out the carb and check the jets and passages for obstructions and dirt.

check to see if the choke is stuck or the carb could be dirty (gummed up)

first drain the carby, then set your air mixture screw 2 turns out, from the fully turned in position. The starting proceedure is as follows, when the engine is COLD, turn on fuel, pull on the choke fully, and kick the engine over. DO NOT use any throttle, when the engine is cold, and the choke is on. Remember Choke on, NO throttle.
When warm, no choke, and a little throttle when kicking.

sounds like you need to rejet the carb..

Hello you have a
1. fuel starvation problem clogged carburetor jets.(clean the carb)
2. Intake leak carb joint/intake manifold.( start your motor get it to idle best you can spray wd40 around the carb joint if the rpms change you have a leak replace the carb joint or gasket/o-ring as needed.
3. crankshaft main seal magneto side leaking or worn main bearing.
check end play on the magneto side remove the cover plate firmly grab the end of the shaft with up an down motion if you can feel it move replace the main bearings and seals.
These are problem that will cause your motor to run lean and hesitate.
Hope this helps you with your problem

Start with setting the air and throttle screws. Turn each one inward until it GENTLY seats. Back each one out one and one half turns. Clean the air filter and starter plunger. The plunger may need to be rebuilt or replaced. Check the pilot and main jet sizes. There will be a number stamped on the side of the jets. The pilot jet should be #45, the main jet should be #140.

sounds like your idle jet is clogged, remove your carb and clean idle jet cause it won't idle or kick start without it...good luck to you friend...Tim
