K&B 7.5 ob exhaust pressure

Postby magicman » Tue Sep 06, 2005 9:00 am

I have an old K&B 7.5 ob that wouldn’t start. I figured out why it wouldn’t start but I cant seem to fix it. There is not enough pressure going to the tank from the exhaust I am getting almost none. What could the problem be?

Thanks for any help.

Hi Magicman first there needs to be a hopper tank on the top of the fueltank. It only needs to be an 1 oz tank. then run the needle out more about 4 turns and see if it runs. there is not much pressure going to the tank. It sounds like more of a restricted line or an air leak in the engine. Which engine do you have. Also check the lowend needle or disc. hope this helps jimmy
