This is a reconditioned unit. It will not run at full throttle unless I turn it sideways! I have clean spark arrestor and sprayed carb cleaner, and am at a loss as to how to get it to run upright! any suggestions? Thanks!
Check the in-tank fuel filter to know it's in the full tank of fuel. Otherwise, I wonder if you have trash on the small fuel filter in the carb? Look good for any possible leaking fuel lines sucking air.
Did it run OK initially and this just started? If so, think back as to what could have started this. Look at your carb linkage close and compare the carb's throttle plate in both situations.
