Chainsaw Repair

You are correct; it is the Zama C1 carb. It is a pain to get everything assembled back correctly and I have not thought about the linkage arm from the trigger to the carb being misshapen so I will check that out. FYI, I did replace the gasket above and below the reed valve. I tossed the old reed valve so I cannot try it with the new carb. It is also a factory part and it definitely made a difference in how it runs so I am inclined to think it is good. In mention of the low speed adjustment, are you saying it can make a difference in how the saw will run at WOT under a load? I actually took it to my local Stihl dealer and had them adjust it but when I got it back it would not run at all under a load. It would idle and would open up without a load but once you put it into wood it would die. I kept tinkering until I got it where it is now. It is very usable but it would be nice to get it 100% and to be certain I am not running too lean or something. If you are very familiar with these saws, does it matter how the fuel line to the carb is ran, above or below the linkage, as long as it isn't in the way of anything? Just a thought.
