This is my second post regarding the install of a rebuilt carb. Tractor starts however, both low and upper RPM range the engine fades as thou it will stall the governor increases the revs to keep it running. This goes back and forth. I have adjusted the linkage to no avail. Same results almost stalls then revs kick in via governor. I noticed when this occurs I can hear air being sucked through the oil bath ac. Also, tractor has no power sputters going up hill as though it needs gas. Checked the fuel line..all clear. I am at my wits end as this is my first older tractor and have limited experience trouble shooting. Will be glad to send pics and video if you can helpme. Tractor performed well before I had the carb rebuilt by Yesterday Tractor rebuilder in Ohio. Thank you. Ed H
