Chainsaw Repair

Based on the IPL's I have the 038's either run a Bing 48A101 or a 48A125 or a Zama C3-S148 or C3-S149. Those are all listed weather a 038, 038S,038M. i would check to make sure you have the right inlet needle. hopefully you kept the old one to compare. Had a husky 394 do the same thing you are talking about would not gain rpm with the H needle all the way in. found out that the inlet needle in the kit was not the one that I needed. But needed one out of a different kit. Look real close at the taper where the needle comes in contact with the seat. Also is your metering lever flush with the chamber floor. You can try to drop the lever below the floor and lean it out that way.
