Turn on gas with the carb bowl off and float hanging and see how much fuel flows.It should be a steady stream.Have seen the seat in the needle and seat swell that only lets gas drip through not enough to keep it running.

Fuel is pouring into the cylinder my Briggs and Straton 310777-0112-E1 and being pumped back into the air filter area and out the exhaust.

Your float is stuck open in your carburator. If you are able, take the bowl off the bottom of the carb, then carefully remove the float. shake it to be certain it isnt full of gas..... if so, replace the ffloat with a new one.....the sliding pin should drop. If you have the model with an electrical wire going into a solenoid at the bottom, carefully disconnect the wire, (remove the negative ground from your battery first) then unscrew the solenoid........clean the needle on either tthe electric or manual as well as the seat........air works metal ever. Replace in reverse order.

I have a Craftsman 9hp 29inch blade snowblower that is basically brand new. It had sat for too long and the gas turned to varnish. I had to replace the fuel line and i rebuilt the carb and it still won't...

Hi timmmarquez, I have the same snowblower. That plug is for a light if you want to install one. Can you smell gas when you try to start it ? If you have spark you can iliminate the kill switch. Make sure you have a clean spark plug to (not a weak spark). Good Luck.

I have an old (10-15 yrs) Craftsman Snowblower, equipped with a Tecumseh Snow King 4 cycle, 5 hp engine that hasn't run in over three years due to having been stored. I emptied the tank and put in fresh...

You are on the right track. Do check the air cleaner, and also check your oil level and condition. If the oil's been in there for 3 years, I'd change it.
Also pull the carb off the motor, and get a spray can of carb spray cleaner and clean the bowl, needle valve, around the float, and in any ports, jets, etc.
Drain a bit of the gas out and check to make sure you've got gas flowing, that it's clean and not blocked.Look in the carb bowl...make sure it's not full of sediment, water etc... Spray all the carb linkage and make sure it's all working freely.
While you're at it, use the spray cleaner to spray off the tip of the spark plug, and use some fine sandpaper to clean up the electrode. Then pull the motor thru with the spark plug out , but still attached to the spark plug wire and check for spark. If no spark, replace with a new one. If it's an older style ignition, it may even have contact points that youll need to clean and regap..

Where is the filter located There is no fuel reaching the spark plug

Any Fuel filter will be connected to the fuel line just follow the gas line no matter where it goes until it runs to the carb. the air filter is usually located on top of your carb.

Carbs are clean but suffering from fuel starvation

try changing one by one the fuel filters there could be as many as 4 or 5 one in the carb, on the fuel line to the carb on top of the engine, in the fule line on the frame rail, in the gas tank, even the sock covering the pump in the gas tank. secondly it could be the fuel pump or the fuel pressure regulator. a bad pump would cause hard starting ( many cranks befor it turns on) a bad regulator may cause a fluxuation in the idle.
good luck

Gas flowing out of overflow tube

If there is any gas flowing out of a Mountain Bike you have serious problems.

In reality you have a Motorcycle, not a Mountain Bike.

It's almost surely a stuck float valve. Try banging on the float bowl with a rubber mallet, but not too hard. You should really take off the bowls and clean them out, then replace the float valve pins and check the floats for any holes or for sticking action. Sometimes the floats will stick open due to rust gunk or old gas gummed up in there. I use Sea Foam fuel additive to help keep the carb clean. You could try running a half bottle of that through a bit, but I'd start by getting that bugger unstuck first.

My 50cc mini bike starts then dies 5 secs after starting. why?

It sounds like you may have 2 problems

  • Bad gas
  • dpossible loose spark plug( bad compression)


dump out the gas put new in
Remove the spar plug and examine the plug if it is wet and black it is fouled
if it is white ad dry it is not getting gas

If you can replace the spark plug if not just clean it with a wire brush put back in and tighten

Finally make sure the spark plug wire is not lose

Best of luck to you
