Hello. This is Nik again.. 
I have some problems that i was hoping someone here could help me with.
First I have had problems "starting" this bike since i got it, however problems.. they only have gotten worse since the start.
(i have replaced spark plug, spark boot and fuel petcock.)
I put the choke on, make sure the fuel valve is on, go to a hill... start to pedal downhill.. waiting for a start... waiting.. pedaling.. nothing.
I try it two more times at least.. then i start to play with the choke... still no start. not even a spark!
I take out the plug and place it back into the spark boot. Then i drive it with the clutch out and i see sparks! Yes, im getting sparks.
So, I take the carborator apart, make sure its good and clean,, yes, and make the needle sit at the "3rd" position" .. and i tried 2nd and 1st also.
I have not been able to start the bike much at all. and I keep wondering if the engine is being flooded. I look at the sparkplug and it is sometimes a little wet.. but not too much.. (i think)
I should mention that gas/oil seems to want to come out of my exhaust pipe here and there.. drip drip. I took off the baffle and noticed a little pool of fuel in the baffle "well" which i had to pour out (about a 1/4 shot glass worth) (havent take off the baffle in a couple weeks.. so that was built up)
I think that is because of all the start attempts. eventually the engine began to flood..
I decided to see if the magneto was bad, i put a new magneto in the engine (bike sat for about 2 days before start attempt)...
and 1st attempt to start with new magneto .. and it started. right up!
sweeeeet. 10 pedals and boom..so i let it idle for about a minute.. i go to take off.. and i stall it out~ doh!
so.. i then go to restart asap.. and nope. not starting again.
that was about 4 days ago. It hasnt started since. And i have gone over all of the trouble shooting..
Today i went and bought cork/rubber gasket material from the auto store 6$. I exacto knifed a gasket to replace the muffler engine gasket just in case it was causing an air leak. ... still not starting.
I read a ton of posts on motorized bike forum trying to troubleshoot...
I found a post saying that spark plug gap should be at .15 (mine was at .25-
.30) so i adjusted it smaller.. hoping
still not starting.
I put the choke on (up).. stand a the top of a hill.
get on, pedal and let out the clutch.
it will not start.
What could be causing this? (compression, fuel, air, spark?)
Ive read a post saying give full throttle at start.. I have tried that also, and no start. I usually do not use throttle when i try to start.. (is that bad)
I think I was flooding ( even though i do not squeeze throttle when trying to start .. so i dont flood .. )) so i would pull out plug, walk bike around a minute with clutch out to burn excess fuel and put plug back in.. just to see if that helped. not really.
in fact nothing seems to make this bike start.
I dont think anything is wrong with it.. the piston moves fine, the head bolts are tightened. the chain is tightened. the clutch cable lets out fine (allows the piston to move and spark to ignite while in boot)
The carb has been looked at a lot. no leeks i can "see" all connections are tight... fine carb.
The bike seemed to start well the first week or two. and I only rode it around rather gently.. i never really "opened it" up at all. (WOT) maybe 6 miles total.. no more than a mile in a day.
I have run out of things to look at! Could it be the CDI? ( not big suspect)
Could it be an Air Leak? ( not a big suspect) all things are tight!
Could it be a magneto problem.. (magneto less than week old!, it started first time i tried to run with new magneto, after that .. would not start)
Could it be kill switch.. ( its not even hooked up. ) no
Could the clutch cable be slipping? .. ( the clutch engaged when let out and piston pumps) no.
Could it be the Chain? ( nope. )
Could it be the spark plug? ( new plug and new spark boot. )
is it the CDI? i have no idea! seems fine during spark test
is it the choke? ( i use full choke to start, then slowly start trying more open choke..each attempt that dont start engine.. no luck)
is the fuel old? ( its not very old maybe a couple weeks , but has only been in the fuel tank itself for about a week)
The mixture is fine at least 20-1 or the 6 oz (2stroke) of oil per gallon
Does anyone think they know?? I am so close to just losing my mind here that i dont know what to do.
I really have tried to be patient.. When things go wrong i try to work them out.. but this is so frustrating because i am so stumped! I am not a mechanic and this is my first engine (see my intro post) but i never anticipated this much of a problem.. Please help me if you can! I want to ride. my life sucks now.
ps (long story short! lol)
