Starts with starting fluid and die

The carbs were overflowing and I took them apart and cleaned everything with carbs cleaner. I changed parts that were worn out and put it back together. Checked and adjusted bench sync.
I didn't connect the air boots to the air box just in case I need to remove the carbs again. Using a 8oz bottle as a gas tank, I connect the carbs to the gas line and they didn't overflow and kept pretty much the same level in all four (Hitachi HSC33). I tried to start the engine with no success. Tried with starting fluid and it ran for about 10 seconds and die with the throttle wide open. Still tring without starting fluid and nothing happened.
Check the plugs and they were dry. Sounds to me that is not getting enough gas. I need some suggestions.
Thanks in advance for the help. :x

 

right there with you fish

 

jets clean? did you try the choke?

maybe not enough vacuum to pull the gas though hook it up the the air box and try it (not sure if that would help or not just a guess)

try not to use a bunch of starting fluid, try dripping some gas down the cabs(if you still have the air box off)

 

I had a starting issue after cleaning carbs.
Taking slack out of the choke cable cured the start problem.

 

the jets are clean and the choke cable has a little slack. Did you started it with the air box connected?

 

Take all the slack OUT of the choke cable.

If you take out too much slack it will rev high when warm. You can put more slack back in later if needed. For now you want it to start so I would err on the side of the choke cable being too tight. It takes only a few seconds to tighten or loosen the choke cable right at the place where it is anchored at the carbs.


I acquired a new paper filter and buttoned up the air box with the filter the way its designed to run.

 

Unless you have increased all the jet sizes, you'll need to put the airbox back on to make it run.

 

ok, today I will hook the air box and adjust the choke cable and try again. I will post the results soon. I didn't alterate anything in the carbs.
The bike was kept in the garage for 2 years and I get it from my brother in law. We tried to start it up and the carbs started overflowing. Then last week I cleaned the carbs and changed bowl gaskets and one main jet. That's the long story short. I can't wait to see this baby running again, iit's a big challenge but I think it can happen.

 

It can take a bit to get started after a complete carb' strip, I wouldn't be tipping fuel in the air intake, thats a recipe for a fire.
Charge the battery & get the motor spinning, it will start.

 

Why only one?

 

I have to ask.
When you cleaned the carbs, did you follow RickCoMatick's instructions as well as Gamuru's instructions for cleaning the enrichment circuit?

If your enrichment circuit does not squirt carb cleaner many feet away, the bike will never start nor idle well.

I also can attest to the fact that it takes quite a few cranks of the engine to get it started and running after the carbs have been cleaned and dried. It takes a fair bit of effort to get gasoline everywhere it needs to go.

 

Ok, here is un update. before hooked the air box I turned the key on and while the engine was turning I put the palm of my hand covering the intake of each carb (one at the tieme) and all of them were sucking pretty good. Next thing I inspected the gas level in all the bowls and they've the same level and they do not overflow. Then I proceeded to hook the rubber boots on the intake (PITB), took slack off from the choke cable, put a new air intake filter, connected everything else and gave her a try. Here is the sad part...she didn't make a single combustion. Drained the battery trying, didn't use starting fluid and when I checked tha plugs they all were dry.
I don't know what is wrong, I'm getting frustrated but at the same time I don't wanna give up.
Hillsy, I only change one main jet because because was the only one with the slot messed up.
The sparks looks kind of weak but I think if that was the case the plugs should be soak and wet after 2 minutes pulling gas into the cylinder.
Guys, need some ideas. I don't know what to do next, I'm kind of lost.

 

if you covered the carbs with your hand then your hand should have had gas on it to.. (that is my experience)

how are you checking the fuel level?

 

I'd begin with nothing less than a fully charged-up battery.
Then, troubleshoot the Electrical Path and make sure you are getting Spark.

When you know you are getting Spark ...
Attempt to Start Engine using Starting Fluid and NEW Plugs gapped to spec.
If the Engine runs or Pops and wants to start ... the problem is NOT Ignition

The Problem is Fuel Delivery.

But, FIRST you need a Charged-up Battery and Strong Spark.

 

Found something, the enrichment circuit in carb#1 was clogged, the others didn't look clogged but I put the bowls in limesol (all that I have tonight). Tomorrow I will cleaned the passages very well and try again. The battery that I use today was the extra battery from my boat.
Tomorrow I will post an update of this mess.

 

Just a thought switch the petcock to prime and let it sit for 5 or so minutes.
try to start it on prime.
If my bike sits for say a week it might take 15 minutes and alot of swearing to get her started.
If I switch it to prime have a smoke then try she fires write up.
It seems the gas evaporates quickly from the bowls.

 

I have a 3/8" gas line from a 16oz bottle straight to the carbs, the gas tank petcock is not working and I want to fix the bike before fix that.

 

I cleaned all the enrichment passages and put everything back together, nothing happened. I noticed that the plugs that are on it are BPR8ES, the manual recommend BP8ES that is non-resistor.
Could that make a big difference or cause a malfunction?

 

No, I'm running with the plugs with the resistor and havn't noticed a problem yet.

 

Out of curiosity what kind of bottle are you using to supply the fuel? You said 16oz bottle just wondering if the fuel is not flowing when the engine is cranked.
