Hard to kick, may take 200 times to kick start it but when it is pulled it will fire really fast and run out like normal. Carb seems to be adjusted right. Any help would be appreciated. Thanks
Check Valve Clearance, particularly Intake Valves. Common Honda problem. Valves will have to be replaced eventually, requiring seat cutting by a machinist.

The ignition timing may be too advanced . Some times if the pull start rope is not pulled hard enough it will kick back, The ignition fires just before top dead center , if not pulled hard enough it will kick back.
did the guy give you the starting method. if not you have flooded the plug and it will only start if you replace the plug or dry it out. method. dont touch the throttle. pull decom lever and kick over 10 times. release lever get topwith kick start. pull decom lever slightly to allow kick start to drop 1 notch. release lever and let kick start back up and kick hard. repeat should start second go.
There is no reason for the idle to take 10-15 seconds to slow to normal. perhaps you have a vacume leak. check all your seal and gaskets between the engine and the carb.also when it is running spray gummout spray or equivilent around the gasket edges between the engine and the carb, if the idle increases when you spray then you have a vacume leak. (intake leak). It may be that this is causing it to be hard to start when it is hot.(not getting enough fuel)
Compressor is locked up. You have an outside chance of getting it to come back if you install a hard start capacitor. When a locked compressor tries to start it gets hot really fast and kicks the power off to prevent wires from overheating. You can get a hard start kit from wwgrainger or refrigeration supply company. Many times they won't sell direct to the end user. The hard start kit gives it an extra boost when it tries to start. Most times this won't work. Usually the compressor has to be replaced because it is burned out internally. The hard start kit is less than $20.00, so its worth a shot.
1. First thing is when was the last time you had your valves adjusted
2. On cold start up twist about 15 times on your throttle, as you do that the accelerator pump in carb will shot gas in cylinder, I have a 2003 yx426 & 2005 yz450 have to do to both of them when cold out to get started
Yes, it does have an automatic decompression mechanism. It is a centrifugally operated mechanism and it is EXTREMELY unlikely that is causing your problems. The two highest probabilities are: 1. Fouled spark plug. Forget what it looks like, put a BRAND NEW plug in. It is the cheapest form of diagnosis you can do. These bikes are terrible about fouling spark plugs and a fouled plug produces the exact symptoms you described. 2. Inspect your valve clearance. Tight valves will also make the bike hard/impossible to start with the kick starter. In some cases, it can be push started, but still won't kick. With tight valves, the bike, although hard starting, will run pretty good, for awhile. Eventually it will burn the valves and quit running though. If your bike isn't kick starting fairly easily, something is wrong and needs to be addressed. The only other issue is making sure the idle speed is set per the service manual. These bikes have a fairly high idle, some as high as 1700 rpms. If it is set too low, it makes them hard to start too.
needle and seat are worn out in carb, to much fuel is flooding cylinder. remove carb, clean, get new needle and seat, set float. problem goes away. pull your plug after kicking. its probably wet.
When you push, or pull start you evacuate excessive fuel, when engine is warm, easier to start extra fuel burns easier.
It seems there is fuel starvation to the carburator,
clean the carburator and fit an 'in-line' fuel filter.
Its adviseable to check the spark plug too!
Check its gap too.
Hope this will help.
