LT2000 won’t start

[jerrycmorrow]

LT2000, type 917273760, Engine - 31H777-0297-E1
Went to run it and started and ran for about 30 seconds. Installed new Chinese carb last year and ran great all summer. Suspected condensation so took carb off and drained, cleaned with carb cleaner, dried with compressed air, reinstalled, put new fuel. No start
I’m being a little lazy plus my mower is stored outside, under cover, and it’s too cold to work on it unless I can zero in on the problem. Anyone can help?

The model - type numbers are on the rocker cover along with the date code. These are what you need to look-up the Briggs engine parts.

The date code is needed in case there are parts revisions made over time.

If it is cold in your area & you are using 30wt. engine oil you will have a hard starting issue, switch to 10w30 engine oil. Check spark plug, air & fuel filters for replacement. Always use B&S OEM Parts for your tractor. Adjust valves with engine cold to specs. page 10 in Operators Manual posted above. Intake 0.003-0.005 Exhaust 0.005-0.007.
Watch youtube video below for valve adjustment procedure engine cold. Let us know if this helps, thanks, Mark
