    Husqvarna 128LD Trimmer Piston Question

    Am rebuilding a 128LD. Received the OEM kit from seller and noticed that the piston has different openings where the piston pin affixes Notice the arch on one side versus no arch on the other. The scored piston that I am replacing has no such arch. Is this critical when inserting the piston into...

    What is Normal Operating Temperature?

    Anyone know what the NOT is for a GCV160 or GCV190? All the manuals I have found simply refer to NOT but none give an actual temp in degrees. I did find a forum where a Honda motorbike was reported at a max of about 210 degrees.

    Honda HRX217 ... what is this spring?

    Picked up a used HRX217 HMA a few years ago & have enjoyably mowed with it for 3 seasons. Recently I saw an HRX video at ereplacementparts.com where a similar model has the lower spring (called a "tension spring" in the video) pictured below whereas mine does not. Mine has the upper spring...

    Split apart General Transmission on self-propelled mower

    I have a John Deere walk behind, JS46 (2010-2011). The tranny (rear wheel) is fine now but since this mower is no longer being made, parts are becoming few & far between. I'd like to open up the tranny and check the grease situation & probably clean & re-grease like I do on my Toro's. I have had...

    Briggs carb, what is this opening for?

    I often cut my own gaskets. When doing so on one of my B&S engines (8.75 OHV Professional Series on a Deere push mower), I had a bit of difficulty lining up & cutting the opening circled in orange on the gasket. It mates up to the hole also in orange on the carb. Then I stopped to think, what is...

    Run engine for testing without blades?

    Am working with a GCV190 for a lawn mower. After several repairs, I fastened it to a test lawn mower deck & attached some blades. I have seen before that this is advised because the lawn mower version of the 190 has the regular flywheel (not heavy like in a pressure washer) & thus needs the...

    Newer carbs now have an adjustment?

    I am looking to buy a new carb for my GCV190. To my surprise, I noticed that many (all?) now have a Pilot Screw. I have not bought a new machine of any type in over a decade so none of my Honda carbs have this. I suppose this allows for some adjustment but not sure what exactly, RPM's maybe? Any...

    GCV190 surges even after trying everything I know

    Friend brought a GCV190 from a pressure washer. Runs on first pull but surges like mad unless choked. Cleaned carb that was on it & tried two known good carbs but still surges. Gaskets in good shape & governor is set right. Air leak from somewhere maybe? Don't have a leak down tester but maybe...

    Rescue GCV190 or not

    Have a GCV190 with a busted cylinder case due to a thrown rod. Remarkably, the lower end, crankshaft, piston, valves & other key parts look fine. New cylinder & rod would cost about $86, very close to the ebay prices for used parts. But here's the question: what issues might I encounter with a...

    Kohler 6.75 issues on a Toro

    Friend brought me a Toro w/ a 6.75 Kohler; bought it used. Starts on 1st pull & rpms are right at 3200. However, after about 30-40 seconds, the rpm's dip audibly by probably several hundred & black smoke (not thick black, but definitely visible) is emitted from the muffler. Then, after another...

    GCV160 or 190 governor oil leak

    Noticed that I have this common leak from where the governor shaft protrudes from the crankcase. Honda machined a recess for a seal but does not include the seal with a new engine. Two videos, Taryl & Doublewide 6, show how to insert the proper seal but warn that you have to be careful not to...

    HRX217 transmission swap for less $?

    I have an HRX217HMA. Probably need a new tranny; tried service but it still lacks guts. Bad news is that new trannys are as high as $250+. But then I ran across this fellow who replaced the original tranny (like mine) with another HRX217 version that is only about $140. He didn't discuss the...

    125B - new one on me

    Hey folks. Bought an aftermarket carb for a whopping $6.99; where else but on Amazon. Not wanting to get into a China bashing discussion. In fact, I have never had a problem with probably a dozen or more aftermarkets. My purpose is to pass along a "first" for me. Turns out, the carb works fine...

    Briggs L-head; what an engine!

    Family member brought me his Briggs 7.25 on a 5 year old Troybilt walk behind. I hadn't seen it nor serviced in a year. Turned it on it's side to drain the old oil; nothing came out. Dipstick showed nothing either. He had somehow failed to check the oil during the last year and also let the air...

    Lawn tractor battery question

    Started & ran my Yard Machines (MTD) lawn tractor about 6 weeks ago & it started fine. Took the 12V battery out & put it back on my trickle charger because I knew I wouldn't be using the tractor again for awhile. Took it off the trickle today & installed it on the tractor again (sanded & cleaned...

    2 stroke oils: Full Synthetic vs Synthetic-Blend

    Last thing we need is another "my oil is better than your oil" thread but my post is intended to get opinions/facts about full synthetic vs synthetic-blend. We know that there are quality brands (JASO-FD Certified and meets ISO L-EGD) in both categories. But for some reason, Stihl, for example...

    Walbro LMT 5-4993, why no solenoid?

    Friend gave me a LMT 5-4993. I want to install it in place of the Nikki that is on my Intek 15.5. The Walbro worked last time he used the tractor (he blew the engine) & I cleaned it good. However, it's solenoid has been disabled; thus, it is only acting as a bowl nut now. I understand the...

    Honda HR216HXA carb question

    Picked up this classic. Looks like it needs a new carb. I believe it has the GXV140 engine; that's what the manual says. In searching for aftermarket carbs, I see the style pictured below; description says it fits the HR215. But it has that little attachment thing on it which mine doesn't...

    Briggs 8.75 Pro Engine; what does the oil filter do?

    Have a B&S Professional Series 8.75 on a John Deere walk behind JS46. I am wondering what the smallish oil filter does on it. I replaced the piston & rings about 2 years ago so I had a look inside the case. Seems that there was some sort of channel leading from the filter to the crank bearing...

    Zerk fitting on self-propelled transmission?

    Picked up a John Deere JS46 self-propelled mower, rear drive. Made in around 2011, JD exited the walk-behind market shortly thereafter. Thus, parts becoming scarce. But it is a good unit & mine is in great shape. To be pre-emptive, I am thinking about trying to add grease to the transmission. It...
