Hello all, new member here looking for some help with a 2001 lt80 that was given to me. This quad has sat for many years without running.
I replaced the battery with a new one. Cleaned out mice life from filter box, belt drive casing area and cooling fan side.
New air filter, spark plug, gas, and pull start. When using the electric start it turns like it's really struggling for a few seconds then pops the rear breaker over the rear wheel. This is why I got the pull start as a back up.
Still won't start with the pull start.
I checked for spark and do have that.
What can I check from here?
Should my starter spin fairly fast? It really sounds like it's struggling.
I have tried spraying starting fluid in spark plug hole then putting plug back in to pull start but still get nothing.
What should I be looking for or checking next?
Thanks for any help. Would like to try all I can before taking it to a shop.

 

could have an tight engine...check compression, check spark.check muffler..I had one the other day with an stoppedup muffler wouldnt run until I unbolted exhaust from engine,,starter would stuggle to turn over it didnt have an pull rope either,,Is rope hard to pull? check for gas in engine these lil fellow are common for the fuel cutoff value[petcock assy] to bypass an flood out engine....just afew Ideals good luck

 

Welcome to the forums.
I don't see where you cleaned the carb.
Providing the motor isn't tight (like mentioned above) I think the starter is bad.

 

Also alot of time starter get burnt up from trying to start with low or no compression..This also will cause not start with pull rope.
