Re: boging when loading on trailor

I think it's trying to keep you from comitting the mortal sin of powerloading.

does it do this any other time, when going from neutral idle to mid speed? Have you tried pushing against something to see if the resistance is doing it?

If it's only on the trailer, perhaps it's the angle of the motor when you are part way up. I've seen motors that are temperamental at different angles--something to do with the fuel level in the bowls.
