Did you find a tank?

 

[pbillyi69]

I found a 120 tank but not a 120 super. they look like they are the same but i dont know. its a friends saw and i ordered the one i found off ebay. it hasnt arrived yet. do you have a 120super tank?

 

[Shane¹]

The 112 through 120 all had very similar tanks with minor variations. The 120 were rounded off by the gas cap and 119 and some others had square corners by the gas cap. You can use any of them as long as it is rounded on a 120. The throttle linkage is different between metal and plastic tanks. Super has primer others don't. Si and 6800 should also be the same if it has a plastic tank. If the tank doesn't have a primer spot you can either drill one or just block it off on the intake they don't need it anyway they start good without it

 

[pbillyi69]

the current tank has the primer spot but wasnt hooked up. it also has the plastic gromit that a fuel line hooks to it also has a hole drilled righ next to the plastic gromit. im not sure how all of the lines are supposed to hooked up. the gromit has a nipple with a tiny hole that i assume is supposed to be a vent with just a line on it and a check valve. there is only one place to hook a line on the carb and the hose going through the tank directly goes to a vent line spot on the air cleaner holder that would just allow gas to run straight into the engine through the venturi so not sure which way they should go

 

[Shane¹]

The one main fuel line going through the plastic piece in the tank should go to the carb the other piece sticking up is the vent. The small hole is where the primer line would come up and go to the back of the air cleaner housing. If not using a primer just block of the back of the air cleaner housing.

 

[Shane¹]

Did you get the 120 tank figured out?

 

[pbillyi69]

i got the tank the new tank plug for the fuel lines hasnt come yet so i havent taken it back apart yet.

 

[Shane¹]

Did the tank you ordered work?

 

[pbillyi69]

I will find out tomorrow or tuesday i hope. i havent had time to fiddle with it yet

 

[pbillyi69]

so i put that saw together yesterday there isnt a pulse line anywhere how is the carb suppsed to be hooked up. i ran the fuel line from the tank grommit to the carb and not sure what to do with the other nipple that is supposed to be hooked to the prime bulb i guess

 

[Shane¹]

Fuel line goes from tank to carb. Other nipple that is straight up is vent. Primer goes from primer to that little t then up to a nipple on the back of the carb flange. Fuel line for primer runs through a small hole in tank right by the tank grommet.

well that's how i have them. it wouldnt start yesterday but im pretty sure it was flooded. i will try starting it later and see how it goes

 

[Shane¹]

Got good spark? Take a good look at the kill switch wire the insulation on them breaks off really easy then short out

 

[pbillyi69]

yes i checked for spark the other day

 

[Shane¹]

Ok really stupid what kind of plug does it have I got my but kicked on a 133 the other day that would not run with one ignition but would with another with a spark plug but had spark with both I was really confused

 

[pbillyi69]

it has a bosch plug and it ran before i changed the tank
