It leaking air around the seams can't be right. I hope the new one takes care of the problem for you! Pm! Looking forward to your next video! Have a good weekend my friend!
Thanks John and you have a good weekend down there too! After getting it all cleared out and cleaned up I may try the epoxy route on it and put it up for a backup. It's worth a try! Stay safe!
Its my understanding that these are just non pressurized containers of charcoal media that absorb fuel vapor from the tank and then hold it until the intake can burn them off. This happens (on a 82 mazda truck) like so: Tank vent goes into canister and fuel vapor is produced under very slight pressure (
Right, the only pressure is from the electric fuel pump to the injectors, and Kohler specs 39 psi on the EFI pump. Thanks for watching and the information you gave!
I know this is 10 months old but you can take those apart and dump the charcoal out, then you can clean the filters located inside the inlets. I had a customer who overfilled the motor with oil and it sucked oil up the purge line into the canister. What a mess.
Interesting. With the mower not running, expanding fumes (hydro carbons) from the tank are absorbed by the dry activated charcoal canister and are held there, excess air is vented. When the mower runs, there sometimes is a vent solenoid that comes on at higher rpms to pull fresh air through the canister and burning it in the engine. This is the purge cycle. This is usually closed at low rpms so the mixture will not get too rich. This is not a high pressure system so leaks are not of concern. It should stay dry in operation or the purge line is not working. Or it is getting raw gas from the tank hose.
Thanks for the info! The vent on top the gas tank terminates on just the other side of the tank. I still find it very hard and very unlikely any siphoning action is going on. For that to occur, a steady stream of raw gasoline would be stringing from the half tank level to the top of the tank....not going to happen. So, I've been filling to the half way level and when parked for the night, loosen the tank lids then barely close till gasket contact. So far no gasoline pouring out the canisters. My local dealer told me he's never heard of it happening.....smh. A dealer in Louisville, KY told me it's giving them lots of problems. Also the purge and vent lines are deteriorating badly, to the point of crumbling. In 5 years this should not be happening. Thanks again!
Hi Hubert, I'll do that as soon as I get a replacement. I mowed for 2.5 hours today and all is well. Before blowing it out, it was basically full of gasoline, which I still can't figure out just how it's getting in there. Thanks for watching!
