if its not one thing its another - top problem now

[ferrytrip1]

Ok - Now I am stuck. With pushrods off the clamshell and the roof the motor works fine, each transmission rotates the same to the limits and the dash light goes out. The clamshell movement is smooth both up and down by hand. No signs of twisting.

When I connect the clamshell pushrods the passenger side is a little jerky and it seems to struggle unless I give the clamshell a bit of a helping hand.

Could I be back to the motor struggling under load?

Any other thoughts or things to check? How can I check if the pushrods are ok?

Thanks, Simon
