I think I may know what the problem is, the brass washer that goes beneath the needle seat was missing, I also didn't know what it was for so I didn't but it in.

Bingo sounds like you found it bc if the washer isn't there youve essentialy lowered your seat thusly the needle never reaches the seat pocket so at rest its still letting fuel in.

Well now I have some place to start when I get back on it, but I will take a brake from that project. On a different note, the carb on that 245 is a pain to get out.

Yes they are

 

[Boomer 87]

Yeah just gotta use a 5/16 wrench and go a little bit at a time.

 

[Kensie1988]

Now maybe I might can get it back in the way it came out lol

 

[Boomer 87]

The poulan will probly treat you better its an HS tillotson, little bit simpler to work on.

Yep, that's what I used but it's a tight fit in there.

Man, If by the grace of the good lord this SEM module in my 70E isn't shot, it will be one of my most prized saws with how much trouble it is to get parts for.

 

[Kensie1988]

So I am assuming this is going to cause a problem?

 

[astnmacgto]

It shouldn't I'm assuming that the pulse port isn't a circle shape like the gasket?

Also, isn't that flange supposed to be cast into the saw?

 

[Kensie1988]

I have no idea, it's two pieces on the dayton

 

[Kensie1988]

The pulse port is a channel and the gasket doesn't quite cover it all

 

[astnmacgto]

It's not supposed to cover it, the hole is in the gasket to provide a route between the carb and the saw so that it can operate the pumping diaphragm. If anything you can try to reshape the gasket hole so it is the same size and shape of the pulse port.

 

[astnmacgto]

On second thought I wouldnt bother reshaping it, it looks fine to me

 

[Kensie1988]

Well what I'm saying is that there is a groove and the gasket doesn't cover the groove all of the way up, you can see a little bit of daylight on the right side of the channel

 

[astnmacgto]

I see what your talking about now, yeah that's not a good thing, the original gasket was I'm sure overall larger. If you can't find a larger gasket I would recommend seeing If a toothpick or something similar will fit tightly in the hole and then fill up the channel with motoseal and let it set up so that only the hole is open and when you put the gasket back on it should fit tightly against the motoseal and no air can escape that way, if I'm unclear please tell me

 

[Kensie1988]

Yea I think your spot on now, I pulled the gasket off because it was stuck, now I don't have a replacement

 

[astnmacgto]

A lot of the kits made are now one size fits all when it comes to the mounting gasket. Most factory kits back in the day had mounting gaskets designed for the type of saw in mind

 

[Kensie1988]

One step forward and two steps back seems to be the trend lol

 

[astnmacgto]

It happens
