Unseizing a Ring Stuck in a Piston

I was rebuilding a Honda GX140 motor that is part of an industrial pressure washing system that I acquired for a mere $100. The engine had been sitting outside for ten years and was definitely seized. The spark plug was missing, so who knows how long rain had been collecting inside the cylinder.

I followed YouTube videos on how to unseize a motor by pouring in a voodoo concoction of half carburetor cleaner and half kerosene. The idea is to constantly soak the piston in the rust-fighting chemicals, jiggle the cylinder frequently, and work the crankshaft until the piston eventually frees up. This happens over a couple of days. The biggest danger is if frustration takes over. You can apply too much pressure and break or score the parts.

In my case, the piston freed up after a reasonable time - two days. There was a substantial ridge of rust at the top of the cylinder wall that took rust eater and some light scraping to remove.

Once the piston was out, the hard part began: the rings were frozen solid into the piston grooves. I started another days-long round of suggested fixes including soaking in the aforementioned chemicals, heating the piston with a heat gun, tapping the rings with a plastic hammer, spraying penetrating oil, and even boiling the piston for 20 minutes.

Hours passed without apparent progress. Then, as the lyric goes, "Just a little change, small to say the least"! Under heat, part of the ring lifted ever so slightly. At first, I assumed it was wishful thinking because the change was barely perceptible.

An hour or two later, something else happened: rusty liquid seeped from a tiny area of a ring. It wasn't even a whole drop but an encouraging clue that the constant spray of toxic products was getting into the right place. All of the tutorials tell you that you must have patience. The problem is, they don't tell you how much patience is required.

In my case, the bottom ring raised and came off first. I used a small pick to get into the gap and work it loose. Next was the top ring. It broke in several places because I was too eager to pull sections off instead of waiting for the penetrating oil.

The middle ring almost broke me. I kept thinking that for 50 bucks, I could abandon this nonsense and order a new part. But hope springs eternal even if the ring does not. 

The final breakthrough was entirely unexpected. I was almost defeated and ready to hit the Order button for the part. But I went back out to the garage to give it one more college try. There seemed to be a subtle change in the ring, where I thought I might be able to get my pick into the gap. Risking stabbing by other hand, I applied more pick pressure than I had previously dared. At this point, if I ruined the piston, I was out nothing anyway, right? 

Wow! Things moved!

In terms of a story, this was the climax. I knew everything would resolve itself fine from that point on. Sure enough, during the denouement, I picked and sprayed, heated and sprayed, and finally had several broken pieces of ring to my great satisfaction.

I shared this small joy with my wife who offered an unenthusiastic "congratulations". Her flat response didn't matter. I alone knew this was a major achievement. I had shown patience and persistence, and triumphed over years of rust and neglect.

Yes, the piston and the rings were unseized and the key parts were not damaged. What's more, I had saved myself 50 bucks with only a week's labour (and 40 dollars' worth of chemicals)!

Bell remote control not working

I just had my Bell 9242 PVR receiver replaced because the old one was acting up. The new unit refused to recognize my existing black remote controllers. 

After half an hour with support going through the remote reset procedures, I had to give up because it was time to take the dog out.

Tonight, I tried Bell Support again and managed to get to Level 2 support. It turns out that there's a new software version in these replacement PVRs and the PVR is not compatible with the old black controllers. They can tell the compatible remotes by the colour of the Select button.

In the end Bell agreed to send me two replacement remotes. They should have included these with the replacement box in the first place. They should also tell their Level 1 support about this. That would save a lot of hassle.

Court Orders Breeder to Pay $2500 After Dog DNA Test Proves False Advertising

Richmond Hill, Ontario, March 24, 2022 - A Richmond Hill, Ontario dog breeder was today ordered to pay $2500 for falsely advertising the breed of a puppy. An Embark Dog DNA test proved that Joanie (now 19-months old) is not a MaltiPoo (Maltese/Poodle cross) as advertised. Rather, she is a mixed breed with only 14.7 per cent Maltese and 8.4 per cent Poodle.

“As soon as we brought Joanie home, people remarked that she looked more like a Shih Tzu,” said owner Ken Cox of Nipissing Township, Ontario. “The DNA test confirmed she is 43.7 per cent Shih Tzu with 20.5 per cent Lhasa Apso.”

Deputy Judge Stanley Baker of the Ontario Superior Court of Justice in Richmond Hill assessed damages at $2500 plus $500 costs for the $3000 purchase. (Claim # SC21000007830000)

In October 2020, breeder Jamshid Hadioonzadeh advertised “4 female and 1 male Gorgeous Maltese X Poodle (MaltiPoo) are ready to go to their forever home” on the classified advertising web site Kijiji.ca. The defendant sold the puppies out of a friend’s house in Richmond Hill.

When contacted by email regarding the DNA breed analysis, Hadioonzadeh replied, “If you don’t [want] this little baby, I would be very happy to return.” Owner Cox and his wife, Vilia, made it clear that they would never give up the sweet little mutt. Instead, they took the case to Ontario small claims court where the judge has now ruled for the plaintiff.

“We felt we had been scammed by a breeder offering a highly desirable breed and feared we were dealing with a puppy mill. We paid $3000 in cash but the seller refused to provide a receipt,” Cox said. “Also, we specifically wanted the non-shedding and hypoallergenic fur of the Maltese and the Poodle.

There was legal drama involving the defendant early in the case. In an affidavit, the process server stated that a local resident identified Jamshid Hadioonzadeh outside Hadioonzadeh’s pet store at 10225 Yonge Street in Richmond Hill but the defendant denied who he was and walked away in an attempt to evade service.

“I then approached Jamshid Hadioonzadeh again being certain that he was indeed the person and attempted to hand over the legal document while stating that I was the Process Server and these were legal papers, but he would not take them so I left it in front of his feet. He got aggitated [sic] and started to threaten so I took a picture of him and I left the area with no further incident.”

The next step will be enforcing the court judgment at an Examination Hearing into Hadioonzadeh’s financial situation, including his assets and bank accounts.

Google Whole Home Mesh Wifi Cutting Out - Possible Fix Disable IPV6

For months, my internet connection has been cutting out intermittently.  I blamed my ISP, Xplornet satellite. The Mesh box would randomly turn from bluish white to red for no apparent reason.

It turns out it may be Google Whole Home Mesh WIFI that is to blame. I saw a post which suggested disabling IPV6 support.

So far, no more cut outs!

A Lawsuit Against Jamshid Hadioonzadeh Over A Puppy Scam

This is where I'm documenting my $2500 small claims court suit against Jamshid Hadioonzadeh. It's over a puppy that he advertised as a Maltipoo but a DNA test shows is basically a mutt.

The case is Claim #SC21000007830000 in the Ontario Superior Court of Justice.

Here's a picture of the defendant taken in front of Pet Market at 10225 Yonge Street in Richmond Hill.

Parsun Outboard - No Restart Fix - Throttle Wide Open

My old 5hp Parsun outboard starts up from cold (choke on) on the 2nd or 3rd pull.

However, once the motor is hot, it doesn't want to restart.

The fix is simple: Make sure the motor is in neutral, choke off, and twist the throttle almost wide open.

I never paid attention before, but there's an info graphic on the tiller that shows this:


As we said in technical writing... "If all else fails, read the documentation."

Keep in mind that this may affect many brands made by Parsun, including Coleman in North America.
