You can't go wrong either way...

Stay away from the 813 unless you intend to race it...

I hear that 813 's run great when they are new but after 3-4 tanks of gas they don't perform as well. Thats is what 813 did, my motor would not run, I was afraid I had ruined my motor I put a 668 carb on and the motor fired right up and has not had any problems . Let us know how things go with your 813 carb.

J.

it has a primer and return line just as an 813, it just does not have the accelerator pump for the extra boost of fuel when you first hit the throttle.. the 813 carb is ok, but not one of my favorites..

How do you tell what model your carb is? Is the model no. ie 668, 813 etc stamped on somewhere? They all look the same to me :blush:
