I see you took the carb OFF of the edger.

No, No, No, He took the "AIR CLEANER OFF"! Now then Jason, the top of the carb. is the thing with the butterfly valve, in the picture. The float bowel is underneath it ! BUT, if you found the govenor spring off completly, did you reattach it, and does it work now???????

I empty out all my units at the end of the season and let them sit for a few days with the cap untightened so that whats left can evaporate. If someone can show me where this carb bowl is that would be helpfull. Mr chuck, can you take my picture and draw a circle around what you mentioned and then repost so I know where this part is that you mentioned.
Is yours a Mclane as well, I know I had the option of the 3 or 3.5 version when I purchased the unit.

Yes I know what a butterfly valve is, ( I am a mechanic when I want to be ) there is no bowl under that, I will post more pictures in a few, thanks

If you look straight down into the butterfly there is nothing at the botom except the throat casting that takes a wild turn heading for the cylinder.

I did mention in a previous post that I re-attached spring and it did no good

Wow, I havn't seen one of those in a while. The carb has a dip tube that sucks the gas right out of the tank that it is sitting on. no bowl, no float, no needle valve. just a venturi.

They are totally idiot proof. Except for crappy gas, and junk getting stuck in the dip tibe or venturi.

And the gas cap getting a plugged up vent hole....

OK well that answers that then no float ect, Rusty can you embelish on how this works, I am familiar with most aspects of how automotive engines operate but even cars that I own or have owned ( going back to late 20s ) have had a bowl with the float on them.
How does this dipping system work, when you say dipping you make me think of cranhshaft dippers before force feed oil systems were used.

YES!,I stop when I have nothing else to offer you. Even If it has no float, and it has a dip tube system, I still think it has to have a main Jet, orfice, or what ever you want to call it. Be it .040, .060, or any size in diameter. I thought it was getting crowded , so I backed out, but I'm back now, Happy? Lol What have you found since I fed the dogs, and went to the store? Is it running now that you hooked the spring back up? Do you have a can of either, to help you start it? The next time you get it running, bounce the S.O.B. up and down a few times for me! Let me know how you stand at this time, and I will dig out my thinkiing cap again if needed.

Playing around with it a litttle more I notice that it runs smooth as a kitten when I restrict the airflow to the carb choking it almost closed so I guess that again its not getting enough fuel for some reason.

[1930]

Yes I would also think that it has to have some way of metering the fuel but again I am not sure where to look and that is what I was hoping someone here could tell me. It has no problem starting and it never has and believe me it bounces around on its own plenty while it is running due to solid tires and no rubber mounts to the frame.
I hate to pull the carb off only to realize that it was not what was needed.
No the spring being re-attached did no good

Glad you got it running Jason! Trim the crap out of the grass, and move on to your next project, untill we have an actual lawn mower engine specialist member to chime in! Lol

Can you see in the tank well enough to see if there is any rust in there? That's ther other thing that happens to old engines...

I suspect you are going to end up taking the carb off and giving it a cleaning. Yoiu will probably need a new tank gasket to do that tho, last time i tiook one of those off I had to beat it sensless to get it to let go...

Youu could try an oz of dry gas or fuel stabilizer, just in case it's goo, but I doubt it will fix anything, it never has for me, it always ends up being varnish or bits of rust stuck in the jet.

>main Jet, orfice, or what ever you want to call

Yes, it has only the part that in an automotive carb would be for high speed...
Most don't even have any metering adjustment, idle is set via a throttle stop screw.
There isn't a lot you can muck up with them, which is nice, but they don't work well in cold weather, which is why you don't see them on snowblowers, and they are kinda inefficient for large engines, they need a restricted airflow to make high velocity air to operate the venturi, which reduces the hp available from the engine rather a lot.

[lzenglish]

Well now that rusty has re-opened this can of worms (no offense intended rusty), pour a little chemtool in the fuel tank to clean out the varnish that builds up over time.! A little, Not Allot, and make sure you either run it thru, or it sits for a week or so, then drain the whole fuel tank, and add new fuel! Thats ALL I got, so again, the Best of Luck to you!
