029/ MS290 project 2 starting reassembly 

Your welcome!

Your welcome. I was in a hurry to get it together and the saw is not that good of a looking saw so I did not bother to clean it much. I did another saw that was mint and I took time to clean it.

My pleasure!

Take the air filter off and make sure the throttle plate is closed. If it it is, you have an air leak.

👍

An 039 engine is the only way to go on one of these saws.

Tractor Tech I got a meteor 49mm on the way. Going to be a nice saw when I’m done. Thanks

Thanks 👍

Thanks!

The bearings do not need grease. Your gas oil mix keeps them lubbed. You don't seals in the bearings, just the factory style seal on the outside.

I was in a hurry to get it together. I may tear it apart sometime and try to port it.

These saws don't use a base gasket from the factory. They use sealer. The squish is not easily adjustable on these saws. The saw can not be a clamshell design if you want to do a base gasket delete.

Good with run run time it has. The cylinder was very close to OEM quality.

Yes...

Thanks!

Yes

I use SAE 30 engine oil as an assembly lube. Some old saws call for mixing SAE 30 oil for you gas oil mix. I just use SAE 30 for assembly, and a lot of it. You can also use 2 cylce oil for assembly.

There are 4 screws that run up through the bottom of the saw through the pan and into the cylinder.

@@TractorTech I got those. Does the pan come out of a MS291?

I have not worked on a 291. I know they are a completely different saw. By looking at a part diagram it appears the cylinder bolts to the plastic case. It does not look like there is a pan like on a 290. www.diyspareparts.com/parts/stihl/diagrams/ms291/021790eb-e198-4a60-9e1b/

Why?

You will see it soon why.........

can you elaborate?

+Oisin Hayse I've never used one. I like that the come with Caber rings. I've heard in terms of quality they are the closest to OEM. I heard the meteor cylinder for a 390 is not a good performer. This Cross cylinder looked very nice, near OEM in quality.

94BULLITT im going to turn a black top husqvarna 61 into a 272xp using meteor

Oisin Hayse Did you check with the dealer on a cylinder? Sometimes the Husqvarna cylinders are the same price as the AM cylinders. The meteor cylinder is still a good way to go.

94BULLITT at the moment in ireland their outrageously priced it would nearly be cheaper to buy a new husqvarna chainsaw than it would be to a oem piston and cylinder kit which is a bit of a joke

The popular cylinders in the US are usually around $100. I got a 346 cylinder for $105. A cylinder for Stihl from the dealer is $250.
