If the belt pulley is not turning (power off) and the clutch makes a noise it is probably the bearing in the clutch. With the clutch powered on the bearing doesn't spin so no noise. I would remove the clutch and check the bearing.

Remove the deck belt Engage and disengage the clutch Does it still make the noise when disengaged? Does the belt pulley stop spinning when the clutch is disengaged? If the belt pulley keeps turning when the clutch is disengaged and make the scraping noise the bearing in the clutch is probably bad.

Most handheld 2 strokes have locating pins in the in the grooves to keep the rings from turning to where a ring end is in a port (bad). And the ends are tapered to fit the pins. I have never had to file rings. OEM or AM I just put new rings on the piston and install. Never had a problem. Not...

Check the tank for rust. If it has flakey rust the Houston we have a problem. The tubes are prone to cracking and are readily available. Did you replace the fuel pump diaphragm?

Could be like the guy who runs a truck repair that got a visit by the ATF because he ordered a bunch of oil filters. Now if you order a bunch of vise grips they will think you run a meth lab.

If you had the carbs off and apart have you synced the carbs?

Never seen a mechanical ACR on a multi cylinder 4 stroke bike. Honda did have one on the XL500S. It was a 500cc 4 stroke thumper that pretty much killed off the 2 strokes used in flat track racing. Back in the heyday of big single racing 2 strokes it was common to have a compression release...

Anybody who had a big 2 stroke single knew how to "straight leg" start a bike. Work the engine around to the compression stroke. Shove yourself up high enough to extend the leg on the kick start out straight and drop your body weight down on the straight leg. Trying to start it sitting on the...

"All single cylinder motorcycles over 250 have a compression release" My kawasaki 350 Bighorn didn't have a compression release.

I have used copper wire in damaged aluminum threads.

Get a couple small zip ties and cut pieces the same length as the holes are deep. Put a piece in each hole and install the carb. Zip ties will fix the wallowed out plastic threads.

I give up.

The cheap HF compression tester doesn't have the Schrader valves at the end of the hose. You can't use it for small engines or motorcycle engines It it ain't like this it ain't gonna work

That or tighten the chuck better so bit doesn't slip LOL 🤭

I have a customer with an RT8. Parts are getting hard to find for these units. I rebuilt the tine drive about 10 years ago. Most of those parts are NLA now. Good luck finding parts.

The commercial Z mowers and the bigger JD and Kubota tractor style mowers and others use Marbain steel blades. There is a big difference between regular and Marbain blades https://www.fisherbarton.com/products/turf-care/marbain/

If your phone gets around 100mbps and laptop around 45mbps it is probably just the wifi chip in the laptop. I will assume you didn't get the ethernet adapter so you can't do a hardwire speed test. If you have a poor signal from the router your speed can slow down because of so many packet...

No mulching kit works well in tall wet grass.

Is your PC wired or wireless? If wireless how far from the router? Open the starlink app on your phone and do the advanced speed test. Results?

Many times when an engine has been loose the bolt holes in the aluminum gets wallowed out a bit just tightening with locktite won't keep them tight. Some engines have enough material I can just drill and tap to the next size. Some I put in inserts and use locktite. If your engine comes loose...

I have a hot staple kit that I use to fix cracks in plastic hoods. Cheaper than buying a hood.

You need some old iron to work on.

Good luck. Hope you get power soon.

Be aware Dish satellites are geostationary over the southern US and starlink constellations are over the northern US. Hope you have a clear view of the northern sky. Your Dish cable is probably RG-6 coax and the starlink cable is a Cat 5e weatherproof cable with proprietary connectors.

No.

Back in my service rep days I would tell customers I was psychotic not psychic so I can't read your mind.

When I was on DSL I couldn't stream netflix without buffering every couple minutes and any large file transfers just timed out. No problems on starlink Still got a couple 1200 baud modems out in the barn. If you need them LOL

No Fibre here yet. I have a few of my networking clients setup with wireless links to barns and other buildings using ubiquiti Loco M5's.

I have not had to contact starlink for customer service. I was an early adopter and pre-ordered and waited over a year for the service to be available. When it was they sent the kit and I set it up and no issues. Frontier DSL was a PITA. Every time you call you get the "You are in a high usage...

I have starlink. I replaced DSL that was only getting 3mbps. I am happy with starlink. Speed test from the starlink app

Need to get a new crystal ball.

Not to make this a TLDR. Aircraft spark plugs are very expensive. https://www.aircraftspruce.com/catalog/pnpages/07-26926-12.php?gad_source=1&gclid=Cj0KCQjw-ai0BhDPARIsAB6hmP6-Upw9O4yC66cF7IrvN3GEoW-s8CPfJe1DbS3ffz70Zne-HL-hcugaAkoTEALw_wcB When doing aircraft annual inspection the plugs have...

You should have .004-.008 endplay of the crankshaft and the block. You place some kind of small pry bar or screwdriver between the block and flywheel and pry up just enough to bias the crank and flywheel up that few thousandths.

If you really want to test a spark plug you need a tester like this. It is used to test and document aviation plugs. No offense but the box the guy sent taryl is just a spark box. Actually kinda useless an it doesn't test plug under compression...

I remove those by installing a longer bolt that bottoms out in the crank threads then use a pry bar to bias up the flywheel and hit the bolt with the air hammer.

If you used a lot of oil when you put it together that can cause a high compression issue. There are lots of Asian automotive compression testers that use 2 hoses the first connects to the guage and has the Schrader valve and then a second hose that adapts the plug thread. Not good for small...

I wonder who the rocket scientists were that thought putting the sediment bowl where you can't even come close to reaching it leat alone removing the bowl. Full of bad gas. I guess I will have to pull the tank to get to it.

Thanks for the links. I am hoping that it is just the points. He wants this for a show on the 8th. The guys who brings me all these relics is a bit of a wheeler dealer. This thing is rare enough he wants to keep it. He just sold 5 pieces. 2 of them were Struck Big Job tractors. That leaves him...

1965 Work Bird with Wisconsin engine. Been sitting for years. Controls rusted up. No spark. Gas left in carb. Plus the 50 other things i will find when I dig into it

I always try to get the highest capacity battery I can for any mower. As lead acid batteries age they lose capacity. The higher the capacity, usually listed as CCA, the longer the battery will last. Interesting fact. I take a battery tester with me that will measure actual CCA when I go to...

On a lot of new "stuff" without being able to scan for error codes you will never be able to diagnose and properly troubleshoot it. Been working on stuff for half a century and made a living carrying a toolbox for over 40 of it. The problem is usually not the scanner but people trying to out...

Had a guy just the other day bring in a JD445 and said I serviced it 2 years ago. The oil filter said 2021 on it. When I showed him he was surprised.

Normally you can just twist the belt onto the the PTO pulley. If it is too tight to to get on the pulley it sounds like something is wrong with the deck. I don't think you have a switch problem.

Put it all back together. Start it up and engage PTO at full throttle. Does it kill engine? If it does remove the deck belt from the PTO pulley. Start engine and engage PTO. Does engine stay running and PTO pulley spin? If yes then you have a deck problem as long as there is no issue with...

A guy had a new $20k mower in for service that burned. He was just out $20k

We had a shop burn down a few years ago https://www.whio.com/news/local/flames-have-engulfed-germantown-lawn-care-equipment-business/Q0La39LcEu8ZKUDvuMVSmK/ Had more than one new customer tell me they had equipment there and their equipment wasn't insured, only the building and tools not...

Don't put flyers in mailboxes. A guy who used to work on mowers before he got cancer was printing flyers and putting them in mailboxes. Got a visit from post office police and was given a mean letter.

Depending on your area a good place to leave business cards is a hardware store and auto parts stores.
