I was referring to the intellicarb cover. I was unsure what that was. I got my little 170 running good yesterday.....guess it was some bad gas. Did a little muffler mod to it and she cuts great.

Hallo,

I have just bought a used ms 180, it has a problem - bogs down when adding rpm, its just like it had the chain brake on but its not. I clened the carb a little - opening up blowing some air in and so, after that it worked ok. then, few days later I started the saw and the same thing happened, it bogs down when adding gas. I assume that the problem is the carburetor, should I just order a new one, which do you suggest, change the zama to walbro or ust buy the original zama which is meant for this saw, or is there any other things to check before buying stuff ? the saw starts good idle is also ok, dont know...

also, I am complete hobbyst, this means just cutting few trees in the garden spring / summer.

BTW this is one great and useful forum, lots of chainsaw specialists here :)

Does it get better after the saw warms up a little. My 180 is a little cold blodded and will bog or die until it warms up a little then it runs great. This seems a lot worse if it has been sitting for a while

well it starts up better when warm, bogs anyway

now its very hard to get it working also, when it starts, runs a little, then stops

thinking to buy one new used carb off ebay, just for testing

I would try rebildimg the carb or if you can find a new one cheap enough I would replace it. The small passages are very hard to clean without pulling the welch plugs out of th carb.

hi, just to inform that I changed the carb for another used one and the saw works like new :clap:

if someone will have similar probs then the carburetor might be the cause

thanks,

Thanks for the info, Brad. I did this swap a couple of weeks ago and it gives the 180 a new lease on life.

For those that are looking for carbs, I have a few dealers in fairly close proximity and prices ranged from $37 to $70. One dealer buys them in bulk and told me his price was $28 each, sold it to me for $40, it was in a Walbro box. The dealer that has them at $32 has to order them but they come in a Stihl box.
Maybe in this case it's actually cheaper/easier to get them from a dealer?

I was able to snag a WT-215 from ebay recently for $25 shipped. Makes a bug difference on the 017-thanks for all the info in this thread and to Murf for sending it to me. Thinking of some mild porting but I am scared I'll mess it up until I get some guidance on porting such a small cylinder...:newbie:

Next up on mod deck is my EchoCs400 and Husky 365.

I have another 180 to do a muff mod on and just wondered if it would be possable to just enlarge the main jet using a jet drill from the stock .45 to say .48?I know it would still be non adjustable but would that work.. the owner doesnt want to spend the 30-40 for the wt215 carb....

I have a Wt-215 already set up for a 017~018 if anyone needs one, you just have to change out the throttle plate and shaft from your stock carb.

Absolutely. It's just a matter of pulling the carb back off several times to get it right. And then if you go too big...............:(

Gasket between carb and air filter box?

Hi all,

I am new here and its my first post. I am attempting this carb swap for my ms180 and noticed there is no gasket between the carburetor and the air filter box it connects to. Is this normal? Or am I missing a gasket? Could anyone spare me a service manual with IPL? I greatly appreciate your input.

Peter
