  1. @50mech Interesting.. I will look into rebuilding the carb and see if that helps.. @DJK Do you think valve clearances could cause a misfire like that? @greg gThank you so much for your detailed post! The points are new and I tried to set them to .020, but they are coming in at more like .024(my bad, I'll fix that). I'm assuming that wouldn't cause an issue though? Spark plugs are also new as well. I will look into doing a wet/dry compression check. Vacuum is steady at 21 inches except when is sputters, then the vacuum needle drops. I have been running it a lot recently and have found it difficult to get the temp above 170(I thought it was supposed to get higher than that?) @Sniper Yeah! I watched his series too! I even bought a cheap valve cutter off ebay to try to fix up my other engine, but it didn't work very well and the valve guides look like they're shot as well. I would love to go as in-depth as he did, but I don't have the tools. 😕 Do you guys know if there is a way to replace guides and cut seats without expensive tools? @dpolloOh ok! Sorry for the misunderstanding. Interesting... The engine number says "PII*20928I*. Which seems like you're right. I don't know exactly how to decode the engine numbers though.. @squirebill @DJK @Sniper @50mech I thought what you guys were saying was interesting so I thought I would take a look at the valve train.. I decided to open the valve covers and take a slow-motion video of the valves to see if I could see anything out of the ordinary. I am no mechanic but I didn't see anything wrong! What I thought was interesting though, was that in the slowmotion video, you can hear the misfire, and occasionally 2 misfires right next to each other. Now, I might be wrong, but because there seemed to be 2 misfires right after each other, too soon to be the same cylinder, my hypothesis is that the misfire is not unique to a specific cylinder but eradically affecting multiple cylinders? Here's the video if you guys want to check it out! (I thought it was pretty cool to watch.) Anyways, I may be reading into it too much, but would be interested in what you guys think?
  2. Thank you all for the input! I am going to try to start isolating which cylinder that misfire is coming from. I will look over the plugs/wires(though they are brand new) as @Sniper suggested. @Go Fleiter Thank you! It's a bit overwhelming, but I am hopeful. I will look at the fuel lines and maybe even carb? And will look at swapping the harmonic balancer as you suggested. @michaelmarks697@yahoo.com Thank you! I need all the encouragement I can get! I am really no mechanic, but a total beginner. A lot of this seems way over my head, but I am learning a lot. @dpollo Thanks for the input! Yes, this engine is from a 46, plymouth business coupe(I believe thats what the PO said) Why would you recommend getting rid of it? I am just interested as this is the closest to ready engine I have found so far. I have the old '52 engine that came out of it, but the valve guides and seats were totally shot. I am a totally newbie, and it seemed pretty expensive to have a machine shop do it, so I opted for a new engine. Also, I have the old harmonic balancer from the old crankshaft, will that be swappable with my current one? I am currently just running it daily, to see if I see any gaskets that are failing so I can replace them now. Any other things I should look for? Any gaskets/parts that are a pain to replace with the engine in? Thank you all so much for the help!!!!! I really appreciate it!
  3. Hello all! I have a 1952 Plymouth Cranbrook project I am working on, and need all the advice/tips I can get. I bought this almost 3 years ago as a "beginner resto project", and I ended up encountering so many issues that I got discouraged and started to think it was an ill-fated attempt. Long story short, I just found a flathead 6 in the area that the PO says was rebuilt somewhere around ~2-5k miles ago. I was able to get the engine on the frame, and fire it right up! So now, I am looking for advice on what to check/verify before putting the engine back in? Currently, the body is off the frame, and I am just working with the engine. My thought is that if I'm gonna do any maintenance or repairs that I need to do it now before putting it back together. So what should I check? I need some guidance as I am honestly just a beginner who doesn't know too much. I would really appreciate some tips from you seasoned veterans. Currently, the only issue I'm aware of is that it has a bit of an occasional sputter. I am unsure of what this might be from, but here is a link to a video of it running if you guys want to listen. Also, I have a bunch of new engine parts(as I thought I was gonna be rebuilding the last engine), so if you have any suggestions on things to replace, I may already have the parts! Thanks in advance!! Here is a video of it running. https://youtu.be/LOspeNQM8Ck
