datzenmike Posted February 20, 2023 Report Share Posted February 20, 2023 Did you look at the small round glass on front of the carburetor. Was the gas level showing in the middle. Don't remember you saying. Did you look down the carburetor with it idling? Was there any gas dripping? Use a flash light for both. Quote Link to comment
None_zero Posted February 21, 2023 Author Report Share Posted February 21, 2023 @datzenmikeI am unsure what you mean by small round glass on front of carburetor. If this is there I have never seen it and I've been all over that carburetor. I didn't look down it yet either it just started happening today and I posted about it while I was gassing it back up so I figured I'd wait for the advice first instead of my normal thing where I ask then just start doing stuff and by the time I see the answer the conditions are likely changed lol. I've been trying to solve this issue in one form or another for over a year and I've basically made zero progress. This last time when I stopped doing what I think might help and only did what you said. It ran better than it has in a long time for the last few days. Though gas mileage was only improved marginally I think. So I'm trying to stick to the ask-listen-then do model. **I assume since you made no mention of oil pressure or level that this likely a non factor? Quote Link to comment
None_zero Posted February 21, 2023 Author Report Share Posted February 21, 2023 (edited) Oh yeah the other thing you didn't mention was the squealing belt. This belt of course only goes around the alternator the crank and the waterpump/fan. It has done this before where it sqeals and eats belts every couple weeks. Maybe I'm way off base. But I'm thinking the fan is spinning and the crank is obviously turning ifnits running so could the alternator be the thing resisting the spin and possibly lowered voltage output cause the choke to be irregular. I'm gonna check the stuff you said but I'm just wondering if this thought is absolutely wrong or highly improbable.. I tried many things to fix that belt issue but nothing worked and eventually it just quit doing it. I hate to belabor the point (this is a lie, belaboring a point is like #3 on my list of favorite things) but, I had a coolant leak from the line that goes off of the main intake back under the carburetor and water was coming out right next to the alternator the rusty discoloration from it is still there but I wonder if this could have done something to the alternator. And now I'm going to check again for a glass thing or dripping gas sorry for the tangent Edited February 21, 2023 by None_zero Quote Link to comment
None_zero Posted February 21, 2023 Author Report Share Posted February 21, 2023 Ok yes gas is dripping down the carb and the choke is open. I'm still stumped on this round glass. Can you show me? Quote Link to comment

I'm still stumped on this round glass. Can you show me? Well, there's your mileage problem and likely the fouled plugs and poor running. There should be a round glass window on the front of the carburetor. The dot indicates the correct fuel level. If yours is dripping inside than it's over filling. Quote Link to comment

Loosen the belt and spin the water pump and the alternator by hand. One is likely seized. Replace it. Fix the flooding carburetor first. Quote Link to comment
None_zero Posted February 21, 2023 Author Report Share Posted February 21, 2023 (edited) Ok now I see why I can't find the round glass. Mine is just a solid plate right there that appears to be leaking a bit around the bottom edge. I guess I need to read the photo bucket instructions again so I can send pictures, also.. how does one fix a flooding carb? Is it possible my inline fuel pump back by the tank has too high a flow maybe? Edited February 21, 2023 by None_zero Quote Link to comment
None_zero Posted February 21, 2023 Author Report Share Posted February 21, 2023 Alternator and waterpump pulley both spin freely with the belt off. So just tighten belt then I guess and it's just a coincidence ? Quote Link to comment

datzenmike Posted February 21, 2023 Report Share Posted February 21, 2023 Well I have never seen one without the sight glass. How would you set the float height? Put some rags under the front to catch the gas and remove the cover. Have a care as there is a small brass part on the end of the float hinge and against that cover. The rag should catch it. Have a look and post a picture. If it's the original pump it's fine. If it was replaced it may be too high a pressure. It's on the outside of the frame just forward of the right rear tire and should look like this... Possibly the float is set incorrectly or the needle valve above the float has debris caught in it and it can't close Quote Link to comment
None_zero Posted February 21, 2023 Author Report Share Posted February 21, 2023 (edited) Ok I can tell you right off the bat. That's not the fuel pump I have. I've got three different pumps one that was on it when I bought it. Another that's identical to that one except new and shipped from China. And a third which I think is a holley I got at advanced. Before I pull the plate off the carb though I want to be sure you meant is their gas dripping down the carburetor while it is running? (I replaced the one that was on it when I bought it some time ago thinking I'd got the wrong replacement and after testing it to make sure it still worked ) when I ordered the identical one I was going off of the old one for visual reference since I didn't know any of the specs on it but I don't remember now what the specs were on the new one either. At least with the holley I can probably look it up. But the other two are almost completely devoid of markings. The only thing on there is stamped the word "out" to indicate direction of flow and a "+" to indicate the positive lead Edited February 21, 2023 by None_zero Quote Link to comment

None_zero Posted February 21, 2023 Author Report Share Posted February 21, 2023 (edited) Here is what I recovered from inside unfortunately I didn't see where the thing in the center was before it fell out of place so I'll need help getting that back where it goes.... actually I just realized I have a picture of it 😅 Edited February 21, 2023 by None_zero Quote Link to comment
None_zero Posted February 21, 2023 Author Report Share Posted February 21, 2023 (edited) As far as I can tell the float seems good solid so can't be filling with fuel. The piece that looks like a tiny plumb Bob is relatively clean and the small collar doesn't seem fouled either, there is some sediment in the recess all that goes into which is the same rusty residue that builds up in the filter from the tank but it's not that bad Edited February 21, 2023 by None_zero Quote Link to comment
datzenmike Posted February 21, 2023 Report Share Posted February 21, 2023 Not the stock pump so it's unknown what the output pressure is. So this is a replacement carburetor? Unfortunately there are a lot of really cheap Chinese knock off replacements out there. Use a pencil to gently lift the float up and close the needle valve. The top of the float should be horizontal.

None_zero Posted February 21, 2023 Author Report Share Posted February 21, 2023 Some damage around the bottom of the housing. Possibly has something to do with the leak. Although I think the rubber seal should stop it before that Quote Link to comment

I'll photo it hang on Quote Link to comment
None_zero Posted February 21, 2023 Author Report Share Posted February 21, 2023 (edited) Also when I lift the float it goes up and stops against the top of the housing. Meaning the black part contacting the top is where it stops moving. (Sorry Pic upside down) Edited February 21, 2023 by None_zero Quote Link to comment
None_zero Posted February 21, 2023 Author Report Share Posted February 21, 2023 (edited) Ok i think I get it I just bend the tab up so that closed its level. Right? I'm not going to actually do that though until you confirm it revise this sorry. I'm figuring it out Edited February 21, 2023 by None_zero Quote Link to comment
None_zero Posted February 21, 2023 Author Report Share Posted February 21, 2023 So when the flange on the needle valve makes contact with the housing it is in and the float is level then it's closed? If so that's what I've got here Quote Link to comment
