OK I had my carb in for rebuild and just got it back today. So I installed everything and hooked the fuel line up and cranked, no fire. I have put an inline fuel filter in when I had everything apart and saw no fuel in it. So unhooked and put the end of the fuel line in a can and turned fuel on both regular and reserve, nothing. So I took the tank out so I could get at it better and removed the fuel filter. There wasn't alot of fuel in the tank so I blew air into the fuel line and heard air coming out inside the tank on regular and reserve. So I added another gallon or so and then was getting fuel in reserve but not regular. I put the tank back in and put the filter back in and opened the reserve, no fuel. So I took the filter off again and am getting fuel. The fuel line isn't going uphill at all but can't figure out getting fuel on reserve but not with the filter on. It's the same filter I have installed on my mowers and no I don't have it backwards!! My mowers have a fuel pump and my 450ES doesn't so maybe can't suck fuel thru with the filter? Most here say it's smart to put one on and I figured with the carb being totally clean it was a good idea. Any idea what kind of filter I need if the gravity feed won't pass thru this one?

Here's a pic of what I used...will these work with a gravity fed tank??

 

[LedFTed]

were you getting fuel to the carb, before the rebuild? so far, it just seems like a gas tank issue. i had to replace both the filter, and the valve, on my gas tank. 00es. there are work arounds here, for both.

I think your petcock might have a screen on it maybe it has some debris on it. Also clean the tank cap and vent line. Try with cap off and filter on. You might also prime the filter to get the filter material wetted first.
These gravity fed tanks weren’t designed for small diameter filters so try a larger one. Any debris plus the added “friction loss” of the small filter might just be enough to restrict the flow.

I don’t run with a filter because i cleaned my tanks and the petcock screen before I rebuilt the carb

So I did get it running but very rough, had to choke to keep running with the filter on. I have to head uptown tomorrow and get a longer piece of fuel line as adding the filter shortened what I have. I have the tank off right now and getting good fuel in reserve, not so much in "on" but don't have a bunch of fuel in there. Just seems with the filter not getting the fuel it needs. I did set the air/fuel screw to 2 5/8 out. Also have the air cleaner off and have to spray into the intake to get going. Will see how it goes tomorrow with a longer piece of fuel line. So unless I can find a better filter gonna go without.

I had the very same problem with the fuel flow in reserve vs. On. Cleaning my tank really well did not solve the problem, even tho there was trash in it. Cleaning the fuel line filter did not solve the problem. Replacing the petcock filter did not solve the problem.

It ended up being the valve? on the petcock - the part that rotates to allow you to select reserve, On or Off. Sorry, I'm not sure if it's considered a valve so I'll call it a dial. When I removed the petcock from the tank I realized there was a lot of gunk back behind and down in the dial. I cleaned it with q-tips and pipe cleaners and put a little penetrating oil on it and my problem was solved. All that gunk must have been keeping the dial from being "seated" correctly in each position. Don't laugh, I'm serious. LOL I hope the fix for you is this simple.

Well this project is quickly going downhill. I got my piece of fuel line with no filter connected. It ran a little very roughly and died. Did this a few times and now it will not fire at all. Choke, no choke, doesn't matter. I even sprayed into the intake and still no fire. I 'm pretty sure it's getting fuel as it was running out the hose before I hooked up. But even if it wasn't getting fuel it should fire with the shot into the intake. I shorted the plug and am getting a blue spark. I checked the six 10 and 15 amp fuses and they are good. I can't guarantee the carb has been put back together correctly as I had it done. I know when posting about my troubles before if it won't fire check compression and timing. I guess before I will take the carb apart to see if anything is amiss. Getting frustrating now....:sad

Well from what I have read, you took the carb to get rebuilt.. Who did it? Dealer? Joe Blow?

IF you have cleaned the tank & there is no dirt why run another fuel filter?

Have you removed the petcock & cleaned if it needs to be?

You say fuel ran out of the line on reserve but not good set ON? This is defiantly a tank issue.

I say make sure thats sorted out 100% Then move on to the carb for any issue...

1) I didn't put another filter on, just straight rubber line.

2) No I have not read about problems getting the 8MM bolts out and don't want to ruin the tank.

3) I don't have a bunch of fuel in the tank so maybe why not much fuel from ON. I don't see it being a lack of fuel as when I just went out and removed the carb I got a bunch of fuel to dump out. If anything maybe too much fuel.

4) I removed the carb to take a look at it, the rebuild was done at our local small engine shop but never had done one like this. So gonna tear apart IAW the service manual and see if everything is as it should be. It was a Shindy kit so should have everything needed, but there were 2 small o rings that weren't used so maybe missed something.

Shindy kits are good from what I've read... small engine mechanic "shouldn't" have messed that up..

IF you don't want to remove the petcock, can you remove the tank, swish gas around dump & repeat to make sure it's clean?

I have had the tank out a couple times and done the above. While out I also used my air compressor to blow back into the tank with the control on reserve, then ON, then OFF. I had good air flow feeding back into the tank on the two flow functions and nothing when turned OFF

Thanks for the ideas and help, much appreciated.

Anybody know where @shadetree has been?

Wish I had more info for you about the fuel flow. I have no idea.
@shadetree is still on New Years vacation. I told him to get back soon before I destroyed this forum with all my supposed expert advice. LOL. I'm sure he'll surface soon.

 

[bcsman]

Honestly I don't think there is an issue with getting fuel to the carb now.

OK good to hear about shade....

 

[shadetree]

still alive outlaws..just been very busy !. have you tried looking into the fuel tank cap not letting the tank vent ?.

 

[retro]

I was hoping to see you around today shadetree, when I logged in. Been very busy myself and have ignored the forums for a few days... glad to see you back!

 

[Boyelectro]

BSC what ended up being the issue? I am working through the same problem on my 02.
