dead hurricane

i just bought a hurricane not runing maybe someone can help so this is what is up the motor was rebuilt and the guy did not know what he was doing the timing was off the plug wires were in the wrong place. but i fixed that and set the valve clerence it only starts when you spray gas in the carbs so i cleaned them and and made sure the pump was working and it does so i am going crazy with this thang so please help

okay, it starts when you manually add gas. fuel pump is working.
 
now, are the carbs actually delivering fuel? pump may work but is it pumping fuel to carbs? are the carbs getting fuel in the float bowl? are there any foreign obstructions in the carbs' fuel circuit, ie. clogged jets?
 
 

the fuel pump pumps until the bowls fill up and then the pump stops is that normal? i cleaned all the jets they were clean the guy i got the bike from cleaned the carbs two times before i got the bike the plugs are new so there not fouled i did take off the fuel line that goes to the carbs and put my finger over it not much presure thin the pump stoped its like its not geting fuel  i am wondering if maybe there is not enough compreson

pump should always be pumping if bike is running. does it pump a lot or a little fuel? you could always bypass the pump as a test to see if carbs will take fuel directly from tank.

i tried to bypass the pump nothing i am cheaking compresson how much psi? in the maual it says (185 +28  is that 28 psi or 185 psi
 

i just found out the bad news no compresson that sux i paid 900 for the bike what a waste

no cylinder compression? on a rebuilt motor? what was rebuilt then? it's not a complete waste. think of it as a long term project.

...the motor was rebuilt and the guy did not know what he was doing...

probably left the rings out so the pistons would slide in easier..... Just tear er apart and find out the problem.

probably forgot to install the piston return springs, too.

Anything yet?
 
He had it bored 50 over and reused the OEM pistons/ rings??
 
Was it no compression on all 4 cyl?
 
You said it runs when fuel is sprayed directly into the carbs but no compression?

 
 
BTW: I commend you for NOT using starting fluid.  Seems to be the first thing people like to grab when something doesn't fire up right away.

i got it runing thank god he had the cams in wrong she runs strong thank you for all the help!!
