Sounds good, thank you.

So, I put a 5.5 head on my stock 1929 Model A 4 banger. Then I started to get some knocking - ok, I see people shaking their head yep. I assume the bottom end could not handle the higher compression. Correct me if I am wrong. But if that is the case, can I order a set of babbitts, or do they...

Yes, that is the one I say before - Thank you much

I have multiple Model A heads in my garage. I can't remember which are good and which are not. Does anyone have a link or pictures of what the 4.5, 5, 5.5 and 6:1 heads look like. I once seen a picture that shows the physical differences, but have lost it. Appreciate it Dean

OK, when I retarded the timing the knock lessened. I pulled the copper connectors on each plug and no difference. Sounds like I need to drain the oil, pull the pan and look at and "adjusting the main bearing". This will be a new experience. And one I am hoping to only do once.

Yes, I am trying to isolate the issue, and appreciate all the feedback. It isn't the generator hitting anything.

I like that idea.will let you know results

Is this something new since the head was replaced? Have you driven it yet? With the higher compression heads they tend to knock much easier. Try to purposely set the timing retarded a bit more and give it a try to see if the noise goes away. Do you have full travel of the advance lever in...

I will head down that road and keep you posted. Thank you much

Yes

So I cracked the head and replaced it with a 6:1 head. Now I have a deep loud knock as I start it and when it is idling, and then hit throttle. What do y'all think it is, and what kind of test do I need to do to confirm what the issue is?

With the standard head on my '29 pickup I had autolite 3076 spark plugs. Should I move to different plugs with HC head?

yes you are right. I need to lock the points down from wandering

Can someone provide me the size of screw, or set screw that is used on the original distributor point block, to hold the adjustment in place for the points gap.

J Franklin, I entirely hope so and feel pretty confident that I have.

Yes, and that is what I have. I just pulled the distributor all apart and it appears that everything is there, I just need the bolt and washer. The condenser was touching the tab underneath, so the pickup was running. It just wasn't bolted to the plate.

Thank you GPierce. The issue I am trying to solve is "I have no screw in the end of the condenser"...And I can buy one but I am trying to understand how is that screw connected to the lower plate.

Yes I see that picture. It basically shows the condenser slides in and there is an screw -item #12 - that screws in the end of the condenser. I know there is a copper screw and fiber washer that screw in there https://www.brattons.com/searchprods.asp (second row down). Im looking to see how and...

Ok, so I have a '29 pickup and it has an occasional backfire out the exhaust. I have replaced the head, rebuilt the carburator and no change. I am thinking I have more or less pinpointed the issue down to the condenser. I have original distributor and the condenser slides in the side. I replaced...

Can somebody point me to a picture that shows how to release the rear brake. I am trying to get the drum back on - it was a beast to remove as well. I think the brake is dragging all the time so I am trying to release it abit. Appreciate your help
