Mine runs great after the rebuild!
The kit should have a variety of o-rings to fit your application.

Put it in easy, use a little lube (soap suds?) and make sure you visually confirm the o-ring did not get discombobulated when installing (both ends). There is one of several opportunities to rush with reassembly and have a leak...

Been there more than once.....

Oh sure, get all technical on us.




Really good point.

I had a similar o-ring issue with my fuel transfer tube. The end at the secondary was not seated well and was spraying fuel all about.

Cloaked, what would be the symptom of a leak in the tube referenced above?

Now that you mention it, I may very have had those o-rings in the kit but thought they were too small to be used on that brass tube. Oh well, I still have those o-rings so this is an easy fix.

Symptom is fuel leaking out of one end or the other... The cause can be one of two things; 1) o-rings not properly in place or 2) the tube is not seated properly (regardless of the o-ring, assuming it is installed properly). There is a far fetched possibility of a tube that has a pinhole leak somewhere.

You can fine o-rings at the hardware store... They are common items per se....

I have also seen the bowl screws (front and rear) leak because of the same issue, not seating the washers properly and there is where fuel can leak also (obviously)....the washers of olden days used to be cork and would tear easily upon reassembly.... Clean the recessed area under the screw head where the washer seats...I have seen leftover residue that will not allow a new washer to seat well.

Thanks for the great documentary of your rebuild. This goes in my PowerPoint collection...

One more word from experience... patience

I didn't touch the AP cam. I figured that whatever was there was working (and it was). Also, your spec sheet lists a 2.5 power valve but Holley sent me a 5.5 in the renew kit. I assume that Holley knows what it's doing so I used the parts in the kit.

Let us know how it works out for you though.

I have come across a number of applications where Holley uses the 5.5 power valve in the 240 hp version and the boat has run quite well so equipped.

Have you tried to go to a shorter stroke with the optional hole to back off on the amount of fuel being squirted? I assume your choke is opening fully.
