Hello, Due to the response to me personally from StarTech (a legend in his own mind), I won't comment further on this thread. Regards Jeff

Hello, Try tapping (lightly) on the carb bowl with something like a wooden (or plastic) handled screwdriver. Sometime the float gets stuck in the up position. Regards Jeff

Hi Jim, Remove the two screws on the carb that hold the primer bulb in place. There is a recess that has a screen in it, is it plugged with debris? Regards Jeff

Hello, I have an old Honda 215 Masters mower with hydro trans, so it may have a different trans than yours, but the trans has a filler cap/dipstick that does come loose from time to time. I'd check to see if it does have a filler cap and if it's loose. Might save you the hassle of returning...

Hello, Poor hot restarts could be bad crankcase seals. Regards Jeff

Hello, Not a West Bend, but a Briggs and Stratton 2 cycle, same engine used on certain John Deere (also rare) walk behinds. YouTube has some video's of these B&S 2 cycles. The Komatsu Zenoah Venture – In May 1987, Briggs & Stratton entered into an agreement with yet another Japanese company...

Hello, Those are sweet mowers (I look for the very rare 2 cycle engine option). I have a machine shop in my basement and could make the blade/blade adapter fit. Regards Jeff

Hello, You probably wouldn't get a lot of power from the flathead Brigs. I'd walk through a rebuild with your son (using stock parts, if needed), then look for a more powerful engine for later. Weren't the "hot" engines for karts a Mac9 (short for McCulloch)? Regards Jeff

Yep, had one with the 321 engine, did a real nice job cutting BTW. They called it a turbo-cut. It started on the first pull EVERY time. Regards Jeff

Nice! I'm guessing 50's to 60's? Has the old script Jacobsen instead of the new block letter Jacobsen. Don't let the guys from American Pickers see that. Regards Jeff

Hello, I'm no expert on diaphragm type carbs, but the main theory is they use a flexible rubber membrane that is "powered" by crankcase pulses (both pressure and vacuum), to pump fuel into the carb where is is metered in the appropriate amounts. It's possible your carb may need rebuilding...

Hello, Echo (on chainsaws at least) doesn't refer to it as a primer bulb, it's know as a purge valve, I'm guessing it purges air from the carb, totally different than a float type carb, where it does force gas into the venturi. Regards Jeff

Hello, I'd talk to a local landscaping supply (I'm talking a mom and pop shop, not Lowes or Home Depot). They will be familiar with the type of grass grown in your area and would give you tips on how to successfully grow it. Regards Jeff

Hello, Check Partstree for Cub Cadet utility tractors, model 5254. I know Cub Cadet used Daihatsu diesel engines and they may have used a Daihatsu gas engine.5254 L (54AL542-710) - Cub Cadet Compact Tractor I saw a carb on one model that was a two barrel design. Regards Jeff

Hello, Hmmm. What is the model number of the mower? I've never seen a Briggs engine on an older Lawn-Boy until now. It could be legit, or somebody may have slapped a newer (Classic Briggs) engine on an older deck. The 2 cycle JC Penny mower had it's name on the plastic shroud.

FWIW, most small gas engines don't use pressure oil lube and aren't designed for operating them at much of an angle (they'll starve for oil and have a shortened life). Kawasaki does make a small gas engine that does use an oil pressure system. Jeff

Hello, Remove the air cleaner and verify the choke is closing completely (cold) when you move the throttle lever to the choke position. If it does, and you still experience hard starting, I would back out the idle needle 1/8 to 1/4 turn. I agree a new mower shouldn't require 4 pulls to start...

Hello, You could call around to small engine repair shops also. Kind of a hit or miss type thing, but someone might have a "donor" mower with the carb you need. Regards Jeff

Hello, Looks like you're inquiring about a walk behind mower with front castor wheels, not a zero turn. I don't own one and have never mowed with one, but did find this string on the my tractor forum. One person replied they aren't real good if your yard is hilly. Push mowers with front...

Hello, Simple solution,,,they are orange in color (can't miss em) and called Kubota. Regards Jeff

Hello, It's hard to label one mower as best, depending on what you're trying to do with it (mulch, bag, vacuum leaves or just cut). Snappers do have the best vacuum action. Somewhat of a downside to Snappers, was they are heavy, something you're not going to lift it, to put in your trunk to mow...

Hello, I like to make sure the rings end gaps aren't in line with any machined ports (if possible), a mute point if the rings are pinned. Regards Jeff

Hello, Small air cooled engines carbs either require a primer bulb, or a choke plate (in some cases both) to start. Honda uses the auto choke system. It's best to replace fuel lines (even though externally it looks ok) when doing any carb work as the inside does break down and the rubber bits...

Hello, Yep,,,hard to beat the old 2 stroke engines. Less moving parts. It's not uncommon to find find old Lawn-Boys still running after 50+ years. I find Honda's are the best 4 cycle engines. Keep clean oil in it and the blades sharp and you'll be good to go for a long time. Regards Jeff

Hello, You could try making a gasket out of cork sheet gasket and some thin walled tubing sharpened to act as a punch. It is kind of hard to get it exact width you need. Regards Jeff

Hello, I've bought front tires for my Kubota BX2230 from Family Farm and Home and TSC. They are Chinese made (same manufacture from both stores) and haven't been happy with them. They started leaking air from the getty up. Regards Jeff

Hello, More than likely the collar at the engine (connects to the shaft) that has a square hole, now has a round one. I try to avoid the Weedeater brand as they are lightly constructed. Regards Jeff

Hello, No, GXV140 rings won't work on a GXV120. Regards Jeff

Hello, I ordered rings for my GXV140 from parts tree.com, and it came with the newer 3 piece oil control ring. Regards Jeff

Hello, It's pretty common for the Duraforce carb to leak at the needle valve causing fuel to pool in the transfer chamber and eventually into the muffler. You could perform a compression check, most of my Duraforce engines pull 105 to 115 PSI. Regards Jeff

Hi Chris, I'm guessing you want as tight a clearance in the valve stem to valve guide clearance, Too tight and the valve stem will bind, too loose and oil will escape into the combustion chamber. Your talking tenths here,,,(i.e. .0001") Keep in mind as metal gets hot, it will expand, as long...

Hi Chris, Hmmm,,,hard to interpret this chart. I'm guessing for your GXV120 engine the intake should have .15 MM clearance for the intake and .20 MM clearance for the exhaust. Not quite sure if this is the clearance for the valve stem to guide clearance or the amount the valve opens? If the...

Hello, You need a 0-1.00" micrometer and 0-6" set of calipers. a set of bore micrometers is useful too. Regards Jeff

Hi Chris, Assuming you have a 0-1.00" micrometer, i'd try to find the largest diameter rod that will fit into the valve guides and then mic your valve stems where they come into contact with the valve guides, if > .001" I'd replace the valve guides. Mine were within 1/2 thou or so (i.e...

Hi Chris, The exhaust valve on my GXV140 looked similar. I used a Dremel hand grinder with wire wheel to remove most of the carbon and did resurface the valve seat face with the compound on my lathe set to 45 degrees. If you had a pool of oil in the cylinder, I would suspect it's leaking past...

Hello, From your pics, the internals don't look too bad. These dimensions are listed in my Intertek manual for the GXV120, standard cylinder bore diameter is 2.262" - 2.363" cylinder bore diameter. Standard piston diameter measured at the lower edge of the skirt and 90 degrees from piston pin...

Hello, I use a Kubota BX2230 for most of my lawn (1 acres), then with a Honda HR215 Masters mower or Lawn-Boy 2 stroke to trim around the house and in areas the Kubota can't go. You'r doctor will tell you to sell the riding mower and use a walk behind,,,LOL. Regards Jeff

Hello, Try a N.A.P.A. auto parts store. They have paint codes for lawn equipment, not sure if they'd have Murray. Regards Jeff

Hi, I can remove any amount of material, the groove width would be the bigger question. Regards Jeff

Hi AVB, I've refaced the valve seat angle on the exhaust valve in my Honda HR215 mower, on the small lathe I have. They aren't hardened, carbide insert works fine. Regards Jeff

Hello, I remember old timers back when I was a kid, saying they don't make things like they used to. Now that I'm an old fart, I'm saying the same thing,,,lol. The engine would be even better if it was one of the old cast iron type, not the "Kool Bore" with aluminum cylinder with no steel...

Hi, To get the pull start on the left and clockwise rotation,(on the PTO side) you're looking for, I'd say a chainsaw would be your best bet. Just be aware some chainsaws have the coil mounted in the housing (I.E. Poulin Wild Thing), not on the engine, so you'd have to use the whole housing...

I'd email Honda, explain your situation and ask what would be an acceptable alternative to Honda Hydrostatic fluid. Regards Jeff

Hello, The middle hydraulic cylinder on my LA211 FEL needs to be rebuilt. Kubota sells a rebuild kit, is it hard to do? I've never rebuilt one before. Regards Jeff

Hi Guys, My 4hp Tecumseh (on a Troy-Bilt Junior rototiller) backfired when running at full speed and real bad when the throttle was pulled back to idle. After searching the web for a cause of backfiring on small air cooled engines, I couldn't find a definitive reason why. I removed the head...

Hi Guys, I noticed an oil leak started at the end of this years mowing season. I searched this Honda forum, but only found a couple related posts. Oil is all over the BBC system, which leads me to think the lower crankshaft seal is bad, however when the mower was tilted on it's side, oil...

Hello, How much motor oil does the Troy-bilt junior tiller take? It has the 4.0 Tecumseh (HS40-55580L) engine. The plastic fill port plug has no dipstick, so I have no way of knowing how much oil is in it. Also looks like there are drain plugs on both sides of the engine. Regards Jeff

It's been a lean year on C.L. for Lawn-Boys, so I picked up this Toro with an early 47PZ2 (points not electronic ignition and no primer bulb on the air cleaner box)) Suzuki two stroke. No model number anywhere. Somebody fitted it with an aftermarket type electronic ignition (see pic). The...

I had an awesome day today windsurfing on the Holloway reservoir and mowing about a 1/2 football field with my HR215 masters mower. Trying to stay in shape at 56 is not an easy thing to do. I can't show a photo of the 3rd thing I like doing too,,,wrong forum,,,lol. Regards Jeff
