I would suggest cleaning the carb (remove it) and air filter. There are a few really small passages in the carb that need to be cleaned which get gummed up due to the 2 stroke mixture and sitting for the winter. (Even if you drained the fuel)

DO NOT use a piece of wire or anything to clean out any small passages. Use carb cleaner and compressed air, put it back on, and see if it's better.

If that doesn't do it, a carb rebuild is in order. Not very many parts on those little buggers. If the cleaning doesn't solve it, it's most likely a bad diaphram from sitting and drying out. (Which I'm learning towards due to the lack of pressure when you prime and having it starve for fuel and die after a minute of running). There is a square plate on the bottom of the carb held on by 3 or 4 screws. That's the cover for the diaphram. Remove the screws and plate and look at the diaphram to see if it has a hairline crack, if it's sticking (there's a spring under it), or if any thing else looks out of whack.

I have a Craftsman 22" Auger type snow thrower with electric start thatwill not start. It had gas in it from last winter. I primed it , I set the choke to full, gas open all the way and, at first, it

if you are using ethanol the check the gas lines for a plug because the ethanol leaves a residue behind that can plug your gas line.

Hard to start

Change the spark plug. Also, The carburators vibrate loose sometimes. Check tightness of the two bolts or screws that secure the carb to the motor. Also check that your primer bulb is really pumping gas to the carb. Pump 6 to 10 times until it is full. Pumping extra is not a problem, it will just overflow back to the fuel tank. Check that when you pull out the choke, it really moves the choke plate and it is not stuck. Choke Should be all the way out right after you prime it. Then pull the rope twice or until you get a sputter. close the choke half way and pull again until it starts (you may need to push prime bulb one time more after 3 or 4 pulls here). Slowly push in the choke as it warms up.

Try spray starting fluid into the air intake, that may get it going.

Well if you are missing parts?...No. How could anyone from where we sit. But the fact that it starts with starting fluid is a great sign however. First off, Fresh gas/oil mix is A MUST! No getting around that. OK first, when you pull the throttle (Give 'er gas) does the little lever at the carburetor move back and forth at all? if yes, then what happens when you hit the primer bulb? Does it push/**** fuel from the tank? (My homelite spits fuel out to the ground when I prime the bulb, most spit it back to the fuel tank however) See if priming it moves fuel. You should see a trail of bubbles in the fuel tubing. You have to see if you are getting fuel at all first. Then does it maintain the prime? If not? Then the primer bulb will usually remain empty. A good prime should always show a half full or 100% full bulb at all times. Let me know what we got so far.

These 4 cycle trimmers need to be primed 10x before a cold start. The bulb will feel *firmer* on the last two or three depressions and you'll know that the carb is primed.

Full choke and and full throttle on first tug should see it hit once with a puff of smoke. Second start attempt should be in choke position two (half choke) and with full pressure on the throttle. Should rev to life on start attempt. Let the engine IDLE for 30 seconds, moving the choke to off at the end of the waiting period. Let engine idle to warm another full minute with no choke, then set to work!

Yes, I think I know the problem because I have the same motor and mine starts right up every time. When you cold start it, you may not be priming it doesn't have enough gas. Don't squeeze the bulb 2 or 3 times, do it about 10-12 times. Full choke and it will light right up. On a warm start, you don't need to prime it or choke it. On a semi-warm start, try half choke and no priming.

Will not start. I prime the unit by depressing the bulb 7 times, the choke is full and the throttle is full. It simple does not try to start.

Ryobi 790r i have changed the gas line and the primer bulb . the primer will mash in 1 good time and then gets very hard to mash in . i fully choke it and it will crank but only for 3 seconds until it...

You cannot flood the engine by pushing the primer bulb too much, unless the hoses are hooked up backwards. The primer does not push gas to the carb, it sucks gas through the carb and returns it to the tank. Top barb on primer is the hose coming from the return side of the carb and the bottom fitting is the hose going to the return fitting on the tank. Look inside tank, it is the one without the filter on it, just a flange with a hole in the center.

If you can see gas and air bubbles moving through the primer and into the tank the hoses are on correctly. If you see bubbles going in the correct direction and then reversing when you remove your finger from the bulb, then the check valves in the primer may be bad. Replace primer.

When you say the primer "gets hard to mash", do you mean it is hard to push in or is it very slow to refill and return to the home position? If it is hard to push in and the bulb is full of gas and the hoses are on correctly then there must be a plug in the line going to the tank or the vent in the gas cap is not working. If it does not return, then it is most likely a plugged filter, plugged line from the tank to the carb, plugged screen inside the carb or a stuck needle valve. The primer is creating a slight vacuum to pull the gas through the carb, which is what the carb does when the engine is running. If there is a full or partial restiction on the supply circuit neither the primer nor the carb can pull enough gas for the engine to run. May need to disassemble carb and clean out any varnish, gunk or plugged ports/jets. Use spray carb cleaner. May want to think about a diaphagm and gasket kit if you do it yourself. If you do not feel confident in taking apart the carb, then take to a repair shop.

4. Do not prime the fuel bulb...this may cause flooding.
5. set the choke to full choke.
6. pull the cord gently until the piston resists then pull hard
7. repeat pull a second time
