    I finally got out to test climb some hills in my 67' CJ5 and notices some stalling. I found this great video and realized some of these mods were done by the PO.



    My 225 came with a Carter AVS and I was wondering why the passage between the float bowl was intentionally blocked. Also, this video gave me new insight into why the PO installed a fuel pressure gauge with a low pressure mechanical pump (worn out maybe) and an inline electric pump.

    Something that was strange was he had set one of the floats low and the other was normal height. Do you think this would work to allow street flat street driving and incline driving? The Offenhauser 360 intake is not split so each barrel feeds all cylinders.

    I ended up setting both floats to stock height and it runs great on the street. I'm thinking I'm going to lower them.

    I used to work at a speed shop back in the 80's and I've worked on a lot of these carbs. I watched that vid & I agree with all his modifications for off road use...I used to use JB Weld to block the passage between the 2 float bowls. Do NOT set the floats at different levels...each float bowl feeds one side of the carb, you'd wind up with one side of the carb running leaner than the other.

    Thanks for clarifying that. My carb did have JB Weld blocking the passage and I'm not sure why one float was way off so I set them to stock when I cleaned it. I'm going to lower the levels and see if there's an improvement. My mechanical fuel pump registers about 3-4 psi and when I flip on the electric pump it goes up to about 5-6 so I'll trying turning off the electric pump when I'm inclined.
