Well Ace, I am puzzled on two planes: 1. why do you keep quoting my post and basically giving me the same answer 5 times?
2. When you say "they replaced the plug", what plug do you make reference to?
Now for the blah-blah. Many people who post here asking for solutions, have a preponderance of never getting back to the forum for what the solution may have turned out to be.
That helps no one. The eventual "feed back" is more important than the initial question. Working at a Mahindra dealership, I was intent on attempting to aid your situation. I asked a pertinent question and received no response.
I cannot tell you how many people have stated to us, "my tractor won't start". We used to ask, "does it crank" and have changed that to, "when you turn the key, do you get any sound from the engine"? because "crank" means different things to different people.
"No it won't crank" we are told and sure enough, the engine does indeed turn over (crank) but it won't start which for some means "it won't crank". This is an important question because it points us in a direction.
Just today I had a "no crank" situation on a tractor with 61 hrs on it. The guy had a snowblower attachment that when he took off last year, he failed to fully tighten a bolt holding the ground cable.
It took all summer and fall to finally loosen to the point of no "ground" contact.
Instinctively, I do a couple things and one of those is to wiggle the ground wire. If it starts, then we solved it and that was gonna be my next advice to you if I'd ever gotten an answer as to what you considered "no start".
I hope you feel better soon. The vax was just a big fat lie to placate the American people in thinking their government was on top of things. That universities are forcing their students to get vaccinated is just a continuation of "stupid and absurd". I mean how many times do they need to say "the vaccine is not a preventative".
I also got the vax and also got the delta variant and after 3 days of 103* temp, I got the antibody infusion which cured me the next day. I did lose my taste and smell for 8 months
The next time I got the rona 10 months later with no booster, I had the sniffles.
Also, I do not have a smart phone. I sit at a computer table so I don't always "come here" even when called like a dog.
