I got my AB-25 running about 3 years ago thanks to all the help here. First time in a barrel and it did not pee. I took apart the intake.piston and cleaned and it peed. Took it to the lake and it did not. Just wondering if it set too high in the water on my 14′ aluminum john boat. Semi v model from the 60’s. I was out in my shed a couple weeks ago and it still had gas in the tank for 3 years ago. It started on the 3rd pull. My grandson wants to go to the lake with it and do some fishing. Is there any adjustment to lower the motor a little bit? Thanks
