Hey everyone....86 spree-Has not run in years////New top end and gaskets-Carb cleaned and blown out twice( Every hole is 100% open and yes even the micro small hole ). Checked spark and looks very good. Tried to kick start ( No Battery in her yet) numerous times and the clear gas line showed no gas coming from tank. Took off vacuum hose from intake and blew into and gas trickled down and filled up carb (made sure by unscrewing screw on bottom of carb bowl). Kicked over many more times and not even a pop. Checked plug and totally dry. Did this a few more and still no gas into cylinder. Yes there is a brand new air filter with cover installed while attempting to start. Changed the bystarter (electric choke) with one that works from a running spree and still nada. Took off intake and checked reeds.....Slight opening on one side and I mean Very Very slight. I dont think that would make it not get fuel but maybe its a poss. Compression seems good...Which brings me to my last question......Is there a chance if the crank seals are leaking that they would cause the top end to not get fuel???? If so is there any easy way to check? Any one with similar Issue????

Technically, Yes, if your seals are gone and the crankcase wont hold vacuum then there probably wont be enough good stuff entering the top end to get it started. Use rubber plugs and a mityvac to test crank seals.
I would start with being 100% on fuel flow from the petcock, search around for info on that. If that checks out then try some ether and see if it will go and stay running. If you are in NY I am sure it is cold there like it is here in MI, my spree will kick start down to about 20*F, any colder and its just a no go without starting fluid. If all else fails, clean the carb again. I am a certified cycle mech and am still surprised how often a gummed up carb that has been "cleaned" is the root of all problems, especially smallbore 2strokes
Thanxs for info....I have recently worked on another spree and with this forums help I totally understand the importance of "a clean carb" .Which is why that one would not run properly after the first carb cleaning. The carb is 100% clean...every port,hole,nuk and cranny.
Not sure what you mean by rubber plugs and a mityvac to test crank seals. Could you elaborate. And what is your professional input on the reeds?
You stated that you "blew" into the vacuum line from the petcock when you should have been "sucking" to create vacuum. Loosen the carb bowl drain screw while you are "sucking" and see if you get a steady stream of fuel draining out. I'm guessing you have a vacuum issue so pay close attention to the carb "insulator" and O-rings. You can do a search and see the insulator and gaskets I fabricated to solve the same prob.
Sorry for not being specific......I was sucking on vacuum line and fuel then started to run down gas line. Like i stated fuel was in carb via turning drain screw and fuel rushed out drain tube. Carb cleaned twice and yes it is totally clean as stated. And it does sound like a vacuum issue since there is not enough to draw down diaphram in petcock. Still lookn for info on reeds.
a small gap wont hurt that much on your reeds but if it is large then time to replace the petals, some people have just flipped them over with good results,but only if they are NOT the metal ones. and have you cleaned the petcock? maybe just replace it. and yes check for leaks at the insulator.

Took parts off the non running motor to put on another motor I had lying around. And guess what????? Taking off the fly wheel from the crank and look what was just hanging all loose and jiggly............................................................................................................
THE CRANK SEAL........Kinda what I expected from my first message I posted. I guess I was barking up the right tree...........pat/pat
It fits in the spark plug hole and smoke is pushed in the motor via a tube,
Slowly turn motor over by hand and plug the exhaust with finger.
Smoke will appear at the leaking point:
reeds,
crank seals,
carb,
or manifold seals,
head gaskets,
bottom of jug,
oil pump.
It takes only a few minutes to diagnose.
