    lt80 bogging down tried everything...?

    recently got a 98 lt80 it was running great and recently it died on trail...

    I have read most of LT80's threads about this and have tried everything...

    What it does:

    starts and idles, give it gas it bogs down and dies
    also If we shut off the choke it dies

    I have the complete service manual for it..

    What I did:
    cleaned air filter,new plug,cleaned carb 3 times all jets everything a-z, cleaned all vacum hoses etc...drained fuel, cleaned feul filter and feulcock , run it on pri so feul will be on all time for testing it

    If I do LT80's 2finger trick choking the carb on my own I can get it to rev and run faster.

    I was thinking the float may have slow leak but it wouldn't run faster when I choke it out manually...?

    I adjusting main needle richnes/ lean and that wasn't problem.
    I was also wondering if stator would cause this but doesn't make sense how it runs fast when I cut off air flow some???
    any ideas... thx

    First off, you need to do a compression test. Sounds like it's down on compression.
    Eliminate that aspect and we can go on.
