700 summit not getting fuel????

[boondockin]

got a 2000 summit 700 that im trying to get going has good spark, acting like the fuel pump is not working, (took apart and cleaned) has fuel going to it, i pulled of the impulse (?) line and blew on it nothing, i took the compressed air and blew on it with that and i had gas coming up the fuel lines to the carbs and it would start and run for bout 30-45 seconds then die, id repressure it and it would doo the same thing. So i hooked it back to the engine and now nothing... Anybody got any ideas or suggestions

Does it have good compression? What shape are the reeds in?

The Pulse line just moves a diaphram back and forth that pumps the fuel. How many (psi) did you put to it. Might have hurt the diaphram. As well as Glens ? The pulse lines pulse comes from the compression in and out of the case. So if you have low comp. you got low pulse.

Remove spark plugs give it a little gas in each hole reinstall plugs pull the rope. Redo untill it sucks up fuel. Pulling the rope doesn`t suck hard enough. May have to do it a few times. works on my old 600. If nothing else will tell you it runs for a second till the fuel is all used up
Good luck
