My LT80 won't start. It's got fuel, spark and compression. It will barely start on starting fluid, then die. I'm not sure why it won't start. If it's got fuel, spark and compression, the only things I can think of would be the timing, or a blocked pipe. I'm not sure. Any help appreciated.

 

Welcome to the forums.
Yes, it could be a plugged pipe.
it isn't timing.
What exactly is the compression?

 

Compression is at 135 PSI, I double checked. I think it's a fuel issue but I'm unsure. I'm positive the motor isn't flooded. What should the petcock be on while trying to start it? ON or PRI?

 

Great comp.
After a carb cleaning/rebuild the petcock needs to be on prime to fill the bowl with fuel then put in the on position.
On is off till there is vaccum made which opens a diaphram in the petcock.
Plug wet?

 

Can't confirm the plug is wet at the moment, I'll check when I get home and try starting it. We would want the plug wet, correct? That'd mean fuel is making it into the cylinder.

 

After trying to start with petcock in the ON position, no choke and not touching the throttle, the plug was wet.

 

Any ideas guys?

 

The pipe wasn't plugged.
How many turns out is the idle screw supposed to be?

 

Any help guys...?

 

this might sound crazy but any help is help... i had a 85 motor 4 that sat for a few years i did the same thing,added fresh fuel,plug,and no start, but spayed a little fuel in the carb and got some sputtering,took the the carb apart and cleaned it and primed but still no start, checked comp spark ect,ect... ok here was the crazy thing i put my hand over the air intake were the air filter goes into the carb and i felt sucktion then the battery started to die, so hooked up the charger and got it turning over fast and so i sprayed more fuel in to the air intake so it would get some gas and put my hand over the air intake and got spuddering i added a bunch more spayes of fuel with the charger on making the engine turn fast and my hand over the intake feeling sucktion it FIRED up took a few time to make it run it self but once it got a full bowl of feul (it seemed) it ran by it self and never had a prob starting again... it was wierd but worked hope it works for u best of luck im in a bad issuse my self so like i say any help is help....
