SOURCE: replacing broken gaslines... were do they go?

the primer bulb draws gas through the carb 'C' and back to the tank'T' leaving a small amount of fresh gas in the carb.to replace the lines from filter to carb & bulb to tank,you may have to remove handle & split the housing halves to find where lines enter tank.look in tank W/ a flashlight.to replace lines cut new line on an angle,feed a piece of # 14 copper wire through hole from inside tank.slide new line over wire,the wire will help align fuel line with hole.use needle-nose pliers to push line into tank,& to pull it through once you can see it.cut off end of hose you beat up with pliers.push filter on hose to carb.drop it back in tank."T' line is the return.dosn't matter which line is through top or bottom hole.

Is the primer bulb replacable on 200 classic chainsaw.or do I have to buy a new gas cap.


Hi Shirley:
My apologies if I'm incorrect, but I've never seen a chainsaw that had the primer bulb connected to the gas cap.
So,,,,,
I'm hoping you're asking two questions at the same time.
1) Primer bulbs are replaceable but it's extremely rare that it is necessary
2) Gas caps are replaceable but only needs to be done if they are broken.
If you reply as a comment on this post I'll be able to respond to you.
Cheers.

Why won't my chainsaw prime?


if no gas will enter priming bulb at all I see only a few possible things for this
(1) gas line broken/melted
(2) filter looks good but has internal plug
(3) primer bulb has a small crack in it (most common )

Stihl chainsaw primer bulb will not fill. Runs but will not idel


The first thing I would check is the gas lines and the primar bulb itself as ethanol in the gas will ruinthe rubber parts in about 6-12 months. If they are still pliable then remove the primar bulb and blow carb cleaner through the passages, you may also have a problem with the low speed jet in the carb causing it to not idle. Good luck

I have a handheld blower/vac: The primer bulb is new and will not pump fuel,not even fill the bulb. I checked the fuel lines to make sure they were correct.(homelite)


I was working on a neighbor's homelite chainsaw and I replaced the primer bulb, it was not intuitive, and I hooked up the lines backwards. Also if you are replacing the primer bulb, maybe you have old fuel lines that are deteriorating and need replaced. Did you check the in tank fuel filter? If it looks dark, it may be time to change it.

I hope this helps get you going again.

Ran out of gas and filled it back up ,now it won't start


If it has a primer pump this as many times as it takes to 3/4 fill the bulb, this will prime the carb, now try again with full choke.

Gas primer bubble cracked. How to find replacement


The part your looking for is called a "primer bulb" and is relatively inexpensive (under $3).

The exact bulb you need depends on the model chainsaw you have. Lacking a model number, I've provided a link to a site where you can verify which model McCulloch chainsaw you have and thus, which primer bulb you need to replace your cracked on with.

http://www.mymowerparts.com/partdetail/1125/15474.php

Once on the page, you can enter "primer bulb" in the quick search box and it will show all bulbs for all the chainsaw models available. About the 3rd section down will have the McCulloch bulbs listed.

Hope you find this Very Helpful and best regards!

Carburetor overflowing


Gas line from primer bulb to carb may be cracked or broken. Check gas lines for damage. If not that then there maybe an overflow problem in side the carb caused by the float shut off not seating correct or worn "o" ring etc.
