Hello all; First let me say that I am new to the saw building scene. Now on to the issue.
I built Husqvarna 365 from a kit that I purchased from HLSupply. For reasons that are unimportant to the current issue, The cylinder got badly scored. So I decided to upgrade from the 50mm to a 52mm cylinder and piston. After installing the new setup, the saw will not stay running. I can get it stated if I hold the throttle in a bit, but as soon as I let off and the RPMs drop below 3k it stops.
Also; I noticed that the exhaust is much smokier than it was with the 50mm cylinder (smells different too). The squish was around 50 thousands so I removed the base gasket which got it down to around an acceptable 40 thousandths, but there was very little improvement.
Really not sure what to do next. Any ideas or advice? Is there some basic mod that I missed?
Thank you for any time or input.
