Husqvarna 345 bogging problem

[kårekloak]

Preview
Have a husqy 345 which is converted with brand new 346xp top end and spacer from 350. The saw runs fine at idle and full rpm, but is bogging at mid rpm (and throttle at mid position) . I have replaced crank seals/bearings and tried several carbs. When I mounted the spacer, I hogged the impulse passage in the spacer so the 346 jug could fit, could I have done this wrong? Any suggestions?

I've tried attatched a video but get error (extension) after uploading

I’m not sure about your bog but you need to upload a video through a site like YouTube to post them.

Hei Kåre! Velkommen til OPE.

Good to see another Norwegian on here. If you could post some pics of what you’ve done to the saw, it would be very helpful for trying to help troubleshoot it. We have some very knowledgeable members on here, and I’m sure it’ll get resolved.
As for posting videos, Pat @Backtroller is correct. You need to upload your video to a a video hosting site like YouTube or Vimeo, then post the link to it here.

Try making the low richer and see if that helps it out.
