Will I have to shield this motor? It's 3 phase and fully sealed, so swarf in the fan is probably going to be annoying until it's removed. I'm more concerned about overheating on low revs with the vfd if it's shielded. I don't use flood coolant.

I'm disappointed!
That link says 'adult content ' but all I can see is the interior of a car!
Someone else said that, thought they were kidding! Try this?
That's a great idea. Won't bother my knees as it's at the back.
I have one Brad, I removed it for the motor/vfd conversion. It will be going straight back on once I've painted a few bits and done the wiring.

My first few weeks in Germany back in 1970 , My wife & I stayed over one December Friday night in a friends flat .You've not lived until you've stared across the bedroom to the door, thinking: "I've got to get out of a warm(ish) bed & make it across to there".
He and his wife slept on the bed settee in the living area cum kitchen diner which had a small wall mounter radiant gas heater in it . We slept in their continental single beds made up as a double bed under a massive proper eider duck down duvet .
Their magnetic recording thermometer showed that it had dropped to minus 8 oC in our bedroom that night . Yet we were as warm as a bug in a rug under the duvet , getting up on the Saturday morning was a novel experience I can tell you .

That red is one hell of a loud noisy colour .

This showed up yesterday, everything in the right orientation, holes in the right places. No toughness in the bore or on the piston that I can feel. I had this ordered before I tried cleaning the old cylinder with oven cleaner. It’s nice and smooth, there is like a dark shadow that I can’t shift. Might just buy another piston and use it and the old cylinder on the other 254 I have.

Piston on
Cylinder on
A wee bit of blue roll to hold the bolts in place
Decompression button on, exhaust on. Just waiting for the carb kit to show now
Check everything is working as should then strip it back down and clean it fully and paint the exhaust

Once you get the dull grey colour in the barrel , usually on the thrust side of the piston travel it's time to replace barrel & piston as the chromed surface has worn away & it won't belong before the piston rings start picking up off the cylinder walls .
If you do a fair few overhauls it's sensible to modify a chainsaw spark plug so it becomes a screw in compression gauge . Then start recording what a fully repaired saw registeres after a complete over haul with pot, piston and crank seals ...pressure test wet & dry are for all the properly repairs gear is .
It a doddle to whip off the air filter , wash of the plug area , give it a breath off an air line , remove the plug & insert the tester . open the throttle wide and pull it over three times ..... doing both a wet & dry test .
That way within 3 to 4 minutes you can tell the owner what it will cost to repair and not be left with a scrap chainsaw and a loss of income due to time taken investigating things when they don't come back to you for a repair or a new one .
I rarely did a pot & piston without replacing the crank seals as well as checking the float of the con rod on the crank . engraved the job number on the body & wrote every thing down on the invoices /quotes as I kept a copy .

First start up went well, two or three pulls and she went. Needs tuned but she’s alive! Tried to put the video up but can’t. Me jumping about like a loon shouting, she’s alive she’s alive was quite funny. Shame none of you will see it
Agree entirely, first thing I do when anything small engine comes in... best thirty quid you'll spend, plug out, that tells you how it's running, two minutes later you know compression, so like you say three to four minutes you pretty much have the history of the machine.

Funnily enough I’ve been looking at pressure testing kits.

Were you in your Mankini?First start up went well, two or three pulls and she went. Needs tuned but she’s alive! Tried to put the video up but can’t. Me jumping about like a loon shouting, she’s alive she’s alive was quite funny. Shame none of you will see it
