ILENGINE, the fuel cap (OEM) "is" vented. And the rollover valve is only one way "to" the connection under the air filter. I added more venting to the cap by drilling a small hole and added a screen to prevent debris. Dirt and dust must have clogged the original air path in the cap. New hole...

Now that is strange. Plus the picture of the rollover valve for my mower on PartsTree does not look anything like mine. Anyway, by venting the cap, any issues with the rollover valve are inconsequential. I do not mow on anything but mostly level 5 acres. Now my latest problem is that in my haste...

ILENGIN, I appreciate the help. I had pulled that plastic valve out on first checking. I had no idea what it was for as I'm ignorant of ICEs. It clearly acted as a one way valve (you call it "rollover"). Found it at Partstree.com. When I suck on the line below the fuel filter, I can draw gas...

Tiger Small Engine - "fuel line running back to fuel tank" from just under the air filter - is a one way (check valve - allowing only air "FROM" the fuel tank but not "TO" the tank. It is clear. Check valve works. Auto Doc's - I was under the impression that the line from under the air filter...

The issue turned out to be with the fuel cap. New one solved. All the pumps work if I flip left to right following the arrows and mount ~1.2 inches out from mower. The old pump even still works. Just a bad fuel tank cap. My neighbor had never heard of this either. It had me mystified for days...

Problem solved..... bad fuel tank cap

Issue with fuel at carburetor. None out when fuel line open into bucket. No fuel in filter. Replaced filter. Able to blow thru lines from carb to tank. The small line under air filter that goes to fuel tank is one way check valve - good flow from tank to inlet housing below air filter. no flow...

Auto Doc's, I checked the three nuts holding the carb. They were snug, so I added some whoopazz to tighten them "firmly". I'll mow in a week or so to test. slomo, I ran test on the fuel using a test kit. 5% ethanol, 0% water in both the gas tank (sample from carb line) and the freshly purchased...

Thanks Auto Doc's. I'll look at those gaskets next week. After I start the engine cold, I have to advance the choke to full open very, very slowly. Over about a 5-10 minute period as I'm mowing. If I do it too quickly,it runs rough and will eventually stall. Once it gets good and hot under heavy...

ZT3 with FS730V was running ~20-30 minutes then would die, fairly easy restart, then die in a bit. Changed filter, found debris in tank (crap in gas can from wasp in fill tube). Cleaned all, new filter. Only filtered gas now. Still dies after getting warm. New plugs, fuel pump, coils. Finally...

Engine slows and almost dies when mowing under full load. It feels like running out of fuel, slows rpm and as it nears stopping may have faint, slight backfire. I replaced both plugs and fuel filter. No change. Not sure how to proceed. It happens after getting fully hot when mowing several...

Yes, the fitting does have a pair of o-rings but they are custom on the fitting. I'm having someone check on availability now. Think I found them on ebay. Thanks for the help.

I've not taken it off yet. Tomorrow. Just tightened a couple of times. Had to dremel tool an offset box end wrench to get it to fit with out doing a full dissassembly. Finally wired a tuna can under the fitting to stop oil from leaking down onto the drive belt. Looks like flare due to the kind...

It's more of a custom tube than a hose. Might be a real bear to remove and replace due to shape. I should be able to get a hose routed thru the compartment. Don't know what pressure hose to get. 300psi? 10,000psi? A guy at the hydraulic hose shop nearby said he could make up one if the fittings...

I've discovered a leak at a connection on the pump hose on our MZ6125 zero turn mower. Parts Tree and others say it is no longer available. # is 539131532 in the book but on the hose is HTB131532POR. It looks like a tube that might be replaced with a stock hydraulic hose of the right length and...
