Husquvarna 55 Rancher Chainsaw wont rev up and bogs?
i put a new ring in it to get it running and first couple of starts it ran good, it could take throttle and rev fine,.... but now it doesnt want to take throttle and when i do get it revved up by messing with the choke with WOT it revs then bogs then revs then bogs and dies it wont idle for more than 20 seconds and cylinder wall was kinda scratched up too...could it be eating away at my new ring??
Do a compression check to see if the cylinder was also damaged. You should have over 120 psi. 150psi would be more ideal with a new ring just put in.
You may also have a carburetor problem, an air leak, or leaky crank seals. 1st make sure your carburetor is set properly. If you have an air leak, that may be why the saw leaned out, overheated, and scored the piston in the first place. You can spray carb cleaner around the crank seals and intake boot on the saw while it is running to detect for air leaks. If you have no leaks the carb cleaner sprayed in those spots will have no affect on how the saw is running.
