Question: Carb clear window viewer gas low in the bowl ??

[destin]

Hey guys

Well I have most of the gremlins in my carb sorted, but the pesky one that remains is this:

- starts up fine

*- until the gas fills up the bowl, like a good decent highrev attempt at taking off or two, it runs fine ( when the bowl is full of gas in the viewer.)
Usually 2-3 attempts at gettign any where in first gear until it powers through and stops sputtering and goes somewhere. After that it runs pretty well.

-* after like an hour after I stop and park the truck, the glass viewer shows the gas is low :

The problem I am having on initial take of is it sputters like it is not getting any gas ( presumably cause there is not gas in the site bowl? )

Is it bad for the gas to lower in the site view that low jsut after an hour?

Any ideas?

The carb should maintain the proper level as soon as you start it. If it is not at the proper level and it doesn't stay there during driving, then I would take the top cover off, clean the inlet screen, clean the inlet valve, sheck the float for leaks and adjust the float height. If that doesn't fix it, I would check the fuel pump for proper fuel volume delivery.

The gas draining out of the bowl is probably unrelated. It either siphons or wicks out of the bowl. Mine does it too and I have never been able to find out why. It drips out of the idle port slowly over night and it is not just evaporating. Other than making it a little slow to start if it is completely empty, it isn't a problem.

Thanks man.

The float was pretty dried looking when it was rebuilt, and looks like someone had affixed super glue to the end of it to plug the end? Something weird like that. I should have replaced it then...

Looks like carb floats are discontinued on SOR as well...

It seems like the bowl does not fill up to the proper height until it gets past the chugging gasping for fuel at first take off.

From what your saying and the condition of the float, it is probably the float leaking...

Any way to refab the float?
Sorry if that is a dumb question.

Cheers

Any one have a carb flo

Usually a leaking float will make the bowl over fill. If the float is hollow metal, you can check it by immersing it in hot water and looking for bubbles. Metal floats can be soldered to fix holes. Maybe the float or needle is sticking in the up position.

Thanks

The float ( if we are talking about the same bit ) was this dried rubbery thing in the carb ( metal at the connecting end. )

Yeah it seems that it is low at start, then when i check it after it has been running well later, it is slightly over the full line on the site glass...

I will check the float needle, but i am thinking it might be the float, or maybe a combination of the two. ugh.

( I think the wife hates it when I have to rev it high on the first take off after it has warmed up to get moving hehe, the sputtering is kinda loud )

Do you know if an updated float can be fitted into a 64 stock carb?
SOR has only 69 and up floats available...

Thanks for your patience while answering my tedious questions man, I appreciate it.

float

it pretty much is like a float in the bog that keeps running if it is leaking so it would have to be sticking up to empty out if it was the float---not leaking and falling down --

I did get some small rust bits that jammed mine and when I looked in the window the float was down but there was no gas and there was pressure built up in the inlet line. I took the line off and sucked the gas and rust bits out out of the carb inlet ---yek, but it worked

then I changed the tank and fuel filter and have been fine since

BTW it didnt start out just empty it ran and coughed and did all that but kept running out of gas as I ran it, eventually though it just stuck and got no gas at all and would not even start

When you crank it can you see gas going into the bowl and the float rising? I suspect if it is it is real slow it is pretty obvious when it is working right it fills right up PDQ

When i open the hood and start her up it barely fills at all ( looking through the site glass ). It has maybe a quarter inch o gas in the site.

When I power through the gasping etc when taking off and it starts running fine, and then check the site glass window, it is indicating a little past the site glass line.

has a new filter and the fresh carb rebuilt with the proper kit.
Might be the tank, but i dunno, strange how it goes away after running it.

Thanks man

Going to take a closer look right now

It is worth mentioning that the problem with the gas level in the bowl may not be the cause of your running problems, but it might contribute to it and it is easy enough to fix first.

valid point

I am gonna try to tick things off the list and get it running correctly

ok update...

When Flaot fills up on start just fine now ( still empties when sitting for a while )
But when the float fills it is over the line for sure.

From what i understand it needs to be at or ideally bellow the line correct?

A) would too much gas in the bowl cause hesitation ( I imagine it would )
Could my problems be simply a leaky, or maladjusted float?

My plan tomorrow is to sumerge the flaot in water ( as was mentioned ) and look for bubbles...
The FSM has the correct adjsutments for the floats, so I will check that as well.
Sorry for the latency in posting, work has been crazy.

Thanks guys, any feed back is appreciated. ( thanks Pin_Head )

Being slightly over the fill line is unlikely to cause any serious problems.

Describe in greater detail what you mean by "hesitation" and the circumstances under which it occurs and the symptoms when it is doing it because I am not clear on what is going on from your original post.
