The 90 has the same top cover and AF cover. I'm not sure what else, if anything....Eric or Robin would know.

The new to me is an 801 .
my 80/90 uses a round drum type (round cover)

what I need to find is the family for the 801 I know the 80 is different so is the 820 .
or is the 801 a design all by itself ?

801 and the 90 are the same cover, I believe you can also put a 90 jug and piston on the saw.

The 801 is closely related to the 80, 81 and 90 - no other (later) models.

This might seem a bit confusing at first. The 80 is from a family of saws called Silver Tops(affectionately labeled). The 801 is exactly the same saw as the 80, except it uses the more modern top and AF cover and AF of the 90. It will even have a plug where the 90 jug has a compression release. Your 80/90 hybred is a common modification where someone took the larger P&C of the 90 and put it on the 80....still retaining the top cover and AF of the 80, which is round. One of the many reasons I like the older J'red s family saws....so many parts mix and match.

I'll see if I can find some old ad lit on the Silver Tops that has been posted here in the past....most likely by Eric.

He has an 80 with a 90 top-end, but still with the 80 top cover and round AF.

He is buying my 801 and was asking about the air filter cover.

Here are some of the 'oldies':

801 and 90 AF cover are the same(louvered in the rear). Some of the early 801 tops may not have had the plugged hole for the 90's compression release, but most have the plug. The 90 came out some yrs after the 80.

This 801 does not have the hole for the the decompression valve.

This 801 does not have the hole for the the decompression valve.

Then it's an earlier model. The 801 and the 80 started production in '70 and ended in '80. The 90 came out in '75....so there are 801's without the plug/hole.

There are a few clues that this is an early 801, and that is one of them.

They're out there....I picked up one on the bay for about $20 some time ago. Even though sawagain.com probably shows 'Out of stock', contact them and ask. Same for Scott @chainsawr.com

I got mine from my uncle, he said it never ran well so I pulled the carb off a 70e I have ( with a burnt top end) and it ran pretty good till the seals let go

Thanks i will

I was always curious why they ran the 80 & 801 in production together. You'd think they would have dropped the AF design of the 80 in favor of the 8o1 eventually. Maybe they were both strong sellers.....I have sure seen a lot more 80's around than 801's.

I can just imagine being a dealer and saying something like, "Well, they're the same saw except for the AF design.".....Ok, but what's the rationale??? Be nice to see production numbers on the two models.

I don't mind the round, flocked filters....even in the nastiest of rotten stuff, never had one clog before lunch....always carried spares. Plus you can tell when they start to clog...you'll lose a bit of power and your four-stroke will start to sound differently.

This has been discussed before, and we don't really know if they did or not at the factory.

On the North American market (Tilton) there is little doubt that the 801 replaced the 80 in 1976 though. Never trust Acres site regarding such questions - there just are too many mistakes there, on production years.
