I just bought a Cub Cadet LT50 and used it to mow several

Customer Question

I just bought a Cub Cadet LT50 and used it to mow several lawns with no problem until a few days ago. At full RPM while mowing it bogged down... starving for gas... when I hit the choke quickly and disengaged the mower deck... I kept it running...Also... didn't realize not to use gas with Ethanol... so I siphoned off the "bad gas" and replaced with non-Ethanol 91 Octane... motor will sit and run full throttle.. until mower is engaged... it will make it about one lap of my yard and quickly try to die... It's very frustrating as I really like this machine. Any help is much appreciated.

Will it run off of choke and mow at all, or only run on choke?

I have to back off choke once it starts taking gas again...

it runs on normal throttle... runs normally for a bit... then bogs down again... starving for gas...

I would attempt to clean the carb out. Sounds like you may have an ethanol deposit blocking the carb jet. Check to make sure your fuel pump is pumping properly, and also check the fuel filter if your engine is equipped with them. Most likely it is a carb issue due to ethanol

How would I clean the carb?
Expert:  JON replied 3 months ago.

remove carb and use carb cleaner or brake cleaner to clean internal jets. Use air if you have access to compressor
