What, no chainsaw. That's nice fire wood, one of those should last a few years plus give you an excuse to get a bigger saw.

I was kinda thinking the same thing. One giant Redwood or Sequoia, whatever it is, would keep me in firewood the rest of my life. Just go out and cut a few cords off of it every year.

Gregg,

From what's been posted here, generally speaking (not etched in stone) the red Craftsman 3.7 are thin ringed while the gray ones are thick ringed. I have no idea if the PowerSharp feature makes any difference.

I had a red thin ring power sharp.
No rhyme nor reason from what I've seen

Gregg,

It is a federal offense to cut any Sequoia tree. I would like to meet the arborist on site and see his equipment on hand

Is one preferred over the other?

The thin ring 3700 builds more compression. I will have to run a 3800 against a 3700 and see how they both fare.

On the 3700 topic I have a Walbro HDB on the bottom beside the L is stamped 8 C . What carb kit should i buy ( part # ) on e bay HDB- 8 / K-10 is this correct ?
This will be my first repair kit install . I try and do it right the first time.

K10-hdb is the full kit with needle. D10-hdb is just the diaphrams and gaskets. Both will work on that carb. IMHO, K10, new lines, fuel filter and vent duckbill are ideal. New air filters are cheap as well.

Watched it last night told myself I can do this . Took carb off to get part # and look it over. I can say the guy that did the vid has small hands .

What ever you do, don't blow the carb out with high pressure air. That can ruin the check valve.

Oh geez...now you tell me Tim. I think every carb I ever took apart, cleaned, rebuilt, I used high pressure air on. Lol
I must be very lucky!

I started out that way and was lucky but several have ruined NLA check valves so I'm careful now. You really don't need high pressure air. 10 psi will clear all fine if you use carb cleaner or better still Sea Foam. I quite often just immerse the body in Sea Foam overnight. Especially on HS carbs. Works great. I dump it through a coffee filter and recycle it as well.

that sounds like something i should have known
i like it

 

[fossil]

A lot of people don't like the HDB's. I've never had an issue with them myself. Lucky I guess. I've had a lot of trouble with HS carbs. Especially the worn out throttle shafts due to the strong spring they use on the shafts which cause an air leak.

Watched vid. He never did put a straight edge across the top to adjust the needle valve lever. Also, his work surface looked to be pretty dirty; I use a new paper, shop towel to cover my work surface. You really want that new dirt in your carb? Also, he was pretty reckless with the blade and screwdriver scrapping the old gasket off. Remember that the carb is made of very soft metal and will scratch easily. Scratches can lead to leaks. I always take the time to get ALL the pieces of old gaskets off; may just be anal but makes me feel better
Other than seeing what things look like you'd be better off studying the walbro manual rather than watching the vid.
I never wear gloves when working on carbs; how you gonna be able to feel what yer doing?
I also soak my carbs but in acetone for a couple of days. Then spray em down with carb or brake cleaner. Then air dry with compressed air being sure to not use high pressure on the little tiny screen which conceals a check valve.
I've rebuilt several and may finally be getting the Gist
Go forth and conquer.

Just picking, I don't have a saw that would put a dent in that tree nor less a limb.
