BX's don't have a fuel rail.
I will bet you have a fuel restriction TO the pump....common on the BX series - fuel gauge sending unit "rusts" and small piece swim around in the tank, and block the tube feeding the hose to the filter to the pump.
I was just trying to make sure he checked some basic issues , I've been working on engines for 45yrs and seen a lot of weird problems - including mufflers being partially or completely blocked by many different things - animals storing food & pcs breaking loose and jambing are the most popular that effects the performance and injector pump valves binding after they got hot / debris clogging injectors after they run a short time - that air_ fuel have to get in and out of the engine , I only had limited info so I tried to help him check those 2 situations -said he checked air filter - he'll figure it out - I gave my 2 cents to help someone [emoji111] best of luckBX's don't have a fuel rail.
This would be the first unit I've ever heard of that has a blocked muffler, if that was the case, it just doesn't happen.
If it had a problem with the injectors or the injection pump, it wouldn't come and go with heating it up.
Fuel tube , line , hose - you can call it something else if that helps understand - whatever works for you - check to ensure you have good pressure going to your injectors - LOL?? - seriously ,
Wasn't knocking your efforts to help at all, just the verbiage, it make it easier to troubleshoot when you have the right terms for parts in the system.
Very Good, I have 3 kubota pcs - ZD28, L3010, KX91-3 and at 1 time or another I run across something unusual, I try to remind people to not overlook the easy basics first - as soon as something goes wrong most think the worst case scenario - after all my yrs I catch myself doing once in awhile , thx for the msg - I'm always looking to help and asking for help as well , nobody knows it all - especially if you have limited information to work with & the problem isn't in front of you !Wasn't knocking your efforts to help at all, just the verbiage, it make it easier to troubleshoot when you have the right terms for parts in the system.
Injection lines would be the word, no fuel rail, as that's a common rail term.
The muffler points down, so, as I said, just never hear of an issue with them, and kubota's run notoriously clean to begin with. But yea I will agree "odd things do happen"!
There was a run on here of BX's that "HST's, Differentials, and Clutches" just going out overnight, turns out that tires were going flat and spinning inside the rims, that was a real head scratcher.
Keep helping, every idea adds to the knowledge base.
