I installed an electric wiper motor after several years of fighting with my vacuum wipers on my 1952 3100. My problem with them is they are only wiping about 1/3 to 1/2 of the windshield. If I set them to park about an inch above the bottom of the windshield they only swing up to about the middle of the windshield. Does anyone know if there is an adjustment on the wiper motor to increase the travel? The instructions that came with it doesn't mention anything about such an adjustment, only how to adjust the parking. My motor housing has locking set screw at the bottom. I'm wondering if it would adjust the amount of travel. Neither the motor nor the directions indicate who the manufacturer is.

My dad always told me, "Don't force it, get a bigger hammer".
