Hey all,

What a great resource here!

Just finished cleaning and rebuilding the carbs and all the synching and linking as listed in the factory service manual.

With muffs in the yard motor starts and runs on high idle, but slowly dies out, no longer than 5 min. Will not start after that point crank as I might! After sitting all day while I'm at work, it'll start again.

On the lake it'll start and then run in gear at 1/4 to 1/3 throttle. More than that and the engine simply dies, just like turning the key off. After running 5 min or so it again slowly dies and then will not start no matter how much I crank.

I have NOT compression tested yet, nor have I started into the electronics. I do have the factory service manual and plan on going through everything.

Any suggestions on what might be a good place to start? This ones got me stumped.

Thanks in advance!

well check compression and check spark when it will not start. does no good to have clean carbs if you don't have compression and spark.
