I did kawasaki dealer work for a long time too (they had Kubota yamaha kawasucky bad boy hustler and outboards). The KAF620 "Mule" had a little pushrod 620cc V-twin. Good little engine but they aren't stupidproof. Had one show up, guy says it makes a weird noise. Ok cool I've seen a...

I bought a 351w block from a junkyard once. Kinda hard to find the 1969 blocks but I found one and gave em $10 fer it. Got it home, standard bore and all the caps were fine. However, at some point in it's life it suffered a connecting rod failure and like most 351 (and 302) blocks, when a...

Jumped on the tractor yesterday at dusk, almost too dark to see. Was going to move the trailer out so I can load the car on it. Got stung 4 times that I can count. Suckers must have a nest up under the seat. Got real sick too. Was a little hard to breathe this morning. Looks like I have...

Most of the new ones have CO alarm and shut down. It's a pain in the neck, problematic, oversensitive piece of 'equipment' that is mandatory now. That's all I am saying.

A long time ago they were NGK MR7J-9. I don't know what they are now, new part number. Maybe MR7F??

these kubota engines aren't known for valve issues. Very seldom are they more than .001 out of spec, even with thousands of hours on them. They are pretty bulletproof, but not stupidproof. If it were in front of me I'd have the head off by now. Just based on the sound, it's got no or little...

easier yet, the eoic method turn engine til exhaust just starts to open. Check intake valve clearance. Then turn the engine til the intake valve opens, then almost closes (but not quite). Then adjust the exhaust valve. Once ya figure this out, you can do a check in a minute or two. Us race...

it's got dead cylinders. 2 of them have little to no compression, one has barely enough to try to run. This based on my experience with them, and my ears/eyes. Put a gauge on it. I would imagine one of them is 150-250 psi, the others probably less than 100. You need to see 350 or better...

propane on diesels has kind of gone away, for lots of reasons. N2O kind of became more popular, even though it's cost went way up too. depending on the engine style, injecting anything into the air intake can hurt it. Most kubota engines are easily destroyed with starting fluid, carb cleaner...

my old boss has a run-in with them he was a deer hunter, hunted with some older folks down in the southern part of the state, on a lease. August, they start 'getting things ready'. Had a bunch of box stands out there and they typically run out there a couple weekends in august to clean up and...

Yeah I'm as patient as anyone but there comes a time when patience runs out. Shops in this immediate area (the well-known ones), I've done business with them. #1 is about 120 miles from here, friends of ours, good folks. Also racers. Left them a rotating assembly to balance in 2013 August...

I sharpened blades for 32 years. I just buy new ones when it's time, which is about every 4 or 5 seasons. But I don't cut nearly as much as I used to either. I have a 'country yard' meaning I let it grow when it wants to, and I'll cut it down as needed but it's not manicured. I keep the...

probably build yourself a boost leak checker and pressurize the system. Fix the leaks if you haven't already. It makes a huge difference. I made mine out of a piece of pvc pipe, a cap on one end and in the cap is a 1/4" ball valve with an air hose fitting, and also a pressure gauge. Open...

depends on the area out here where construction is HOT, getting someone to do anything outside of working for a construction company is tough. Same for electricians, HVAC, roofing, etc

twin scroll doesn't necessarily "weaken the power", all it does is to even out the pulses going to the turbine wheel, which helps it spool sooner (reduces lag, and improves overall turbocharger response). That is it's only purpose. Improving response is nice in automotive applications as the...

I'm guessing you've got one of the old (1 or 2 year only) "big" starters? Those are hard to find. VERY hard to find. I normally used a PMGR starter to replace those big heavy things anyway. They start better, use less juice.

do a intake pressure test and see if there's a connection somewhere leaking. Basically you'd attach a piece of pvc with a ball valve and a air hose fitting to the front of the turbo, and apply 10-15 psi to the system. Then use soapy water to find leaks. I do it periodically on my truck and...

microsquirt...oh fun. had one on my old SVO. Pretty easy, for the most part, and in the case of the svo, opens up a TON of options that the stock PE ECU wouldn't support, such as bigger injectors, coil-near-plug (and individual cylinder timing) and removal of the vane air meter which is a...

take the smaller wire off of the starter and then put a new fuse in. Try starting the engine with that smaller wire OFF. If it blows the fuse again, you have a short to ground situation somewhere in the wiring. Wiring on these is pretty simple but you have to know at least a little about DC...

I've done quite a few on sxs's but they're made specifically for the model (Ranger 570, Ranger 500, etc)-and there are some differences you will have to do some fabrication to make it fit your kubota the EPS motor assembly is pretty bulky and it goes inline with the steering shaft that goes to...
