What's on your bench today?

[Richard Thompson]

I've also got a stihl ms250 on the bench not running correctly. I've never seen a stripy piston wall before? any ideas on a possible cause before i strip off the cylinder head to check the rings

 

it does squeek a lot when it does run ??

[TGB]

Perhaps it's been run on Esso.. puts a tiger in your tank. (Only people of a certain age will know what I mean.)

Not seen one like that before. Perhaps some sort of aftermarket one, looks in reasonable condition though.

Had a 066 in for porting, just needed a new clutch drum as the original was knackered. Finished porting a 372XP, a few issues with the coil but got over those.

 

Also got another MS200 in, the crank bearings are pretty rough so got new ones to fit. Just finished porting a 346XP and have another 372XP to port next week.

 

Also fitted new brighter lights in the workshop and been shifting one of my log stores to a better place in the back garden.

Spud have you ported or muffler modded any of the x torx 372's?

I have ported a couple, the very flat floor of the exhaust port is a worry on those saws and there isn't as much to be done as on the older version but there are improvements that can be made.

Had my saw back a week now after spud fixed it for me. It's running great thanks spud. Clogged down a big ash with it today, but it was hard work without the dogs, so I dug them out and fitted them on

Thanks Will, guess it was nice to get the saw working after you messing with it for so long and getting a sore head:thumbup: Fortunately it wasn't the time waster it could have been and was in pretty good overall condition apart from the parts I changed/replaced.

 

Glad it is back earning money:thumbup1:

Turns out it was my botched attempt at a crank seal change on the flywheel side. Leaking under pressure.

 

How can you check for vacuum leaks? It held 10 psi for ages, tried squirting some fairy liquid but no bubbles.

Not sure I follow you, if it is holding 10psi, it is holding pressure as vacuum is measured generally in inches of mercury.

 

I usually put a vacuum on the engine and if it leaks, you need to apply oil or lube spray to typical areas it may leak and it will hold vacuum for a short while until the engine sucks in all the fluid and starts leaking again.

 

Seals can leak one way and not the other - pretty common!
