Finally found AT2 in pretty good shape



I bought this AT2 knowing it had issues but looked pretty good. I enjoy working on them …

The piston slap was so bad I had to tell the seller to please shut it off. He had no idea.

I had it bored to new piston and rings. Then the engine ran away to 5k and even though I replaced both crank seals only one was popped. Clutch plates wore out so I replaced those too.

Giant spark, motor just turns. Carb issues so I sent to a professional carb rebuilder and found jets and needle sizes wrong.

Got it to pop off a few times since the motor was flooded. Going to put the other carb back on along with the tank.

Kicking it seems to help too. Got the air out of the oil pump so I’m running straight fuel tomorrow after she’s all back together.

Thanks for everyone’s help
