In this episode i show you how to set the initial base timing on a 1987 jeep YJ wrangler with the 258ci 6cyl engine. Music Credit: Hollow Eyes - Blanket Barricade Going Higher - Bensound
I've watched several videos on adjusting timing and yours was the most detailed, actually showing turning the distributer, testing, running again. Also liked that you mentioned to be careful of the timing light wires. Good stuff - thank you!
I love military guys doing DIY videos, they make great instructors. And they always include the details. There's 1 suggestion I would like to make, you might include is if the vacuum hose is connected to ported or manifold vacuum. Good video.
Thank you! I haven't made many videos and was trying to capture what most videos i had found were lacking.. hopefully those who view it find it helpful!
I have an HEI and a weber. I only have a couple vac lines but my wires on the firewall are still way more than needed. How did you clean up your wires in the engine bay?. I mean mine are cleaner than stock but yours looks a lot thinner.
Hi may I ask you something?Can you tell me on amc258 6 inline the timing marks for the timing chain to replace? Cause I did it and since then I have backfire from the excaust and doesn't work well
If the timing is off would it cause it to sputter at the top end of 3rd gear and the worst in 4th gear. I just bought an 85 cj7. Changed the ignition module but didn’t fix the issue. Love the video!
Yes, this was a mistake on my part. I should have been more clear on this video and said “this is how you set initial timing.” The vacuum advance will advance timing with increased RPM
I bought a jeep from a guy up the street, and they didn't have the Haynes manual for it, it's an 89 YJ 2.5 4cyl. Would the timing be the same for this? Been doing some research and I'm not getting a lot of answers for a 2.5L.
unfortunately, i have sold that particular jeep a few months ago. Not entirely sure which Weber carburetor was on it, but i do know it ran strong and smooth throughout the entire RPM band, and once i had it tuned, never ran lean or rich from what i could read of the sparkplugs. Not sure how well a weber performs on offcamber or steep inclines for offroad capabilities.. However i will tell you the best 2bbl offroad carb you can get is a Motorcraft 2150. Many jeeps came stock with them, and it's the same carb my 82 wagoneer has and will continue to chug and idle along even with headlights pointed at the sky :)
I just found your posting. That is a Chinese copy of a 32/36. Not a 38/38, which is virtually the same size as the Carter BBD and Motorcraft 2100/2150. The real Weber 38 DGES is the realistic same size and is closest to the stock size BBD and 2100. Fact
I was wondering the same thing. In the video he went back and forth but never mentioned which way was advancing the timing. I guess just turn it one way and check it to find out. I'm thinking it's clockwise though.
adding an O2 sensor is a great benefit for tuning the air fuel mixture on any engine but not necessarily a requirement. This particular engine is carbureted and has been tuned through extensive engine runs and reading of spark plugs to the point where it is as efficient as i am capable of getting it. If you're looking to tune the air fuel mixture, you can do some reading on the basics of spark plugs readings and then tune the carburetor if you're so mechanically inclined
Hello I brought this truck off the person you sold it to, did you rebuild the transmission as well? And was it burn rich when you had it, it seems to burn gas fast. Thank for your help
T Williams I don’t believe the transmission was rebuilt when I had it, nor did I rebuild it. I had tuned the carburetor to run smoothly and correctly when I had it, it’s possible the gentleman I sold it to may have tuned it differently. Do you enjoy driving it?
Jason Kman trying to get it up and running is burning a qtr of a tank fast and the tranny is having issues is there a way to chat on Facebook or etc. the person let it sit for awhile so I had to do some work on it
T Williams If it’s been sitting I recommend a carb rebuild. It could have an air passageway plugged causing a Rich condition. If that doesn’t solve it, it could require tuning the idle air mixture screws, or even re jetting. Pull the spark plugs to see if it’s been running Rich 👍🏼 I don’t know what to say about the trans... make sure it has the right level of trans fluid. Check it on a level surface, with the Jeep idling In neutral, and at operating temperature. If that doesn’t solve it, I recommend a trans filter change :)
Good article, One Small Suggestion, In the beginning remove distributor cap and show direction of rotation of rotor, so it will be easier for some to understand whats really going on about the "Timing Advance". When the distributor is turned, the "cap" is Advanced or Retarded, in relation to the arc of the rotors turning.
Starter is loud. Might need to shim it. Remove the bell housing cover. Watch the starter gear mesh with the flywheel teeth when a second person starts it. Starter gear should go roughly 3/4 the way INTO the flywheel gear. Not fully into the flywheel gear teeth.
those flex fans are junk that rob a bunch of power, go to the junkyard and find an electric fan and get an adjustable temp switch from the auto parts store. This set up will work way better!
The procedure you took was correct for aftermarket or nutter bypassed OEM carbs. If you can get away without pinging you can go even more advanced. 8 is okay. I like 10-12.
I hate my weber I'm converting mine over to a Holley Sniper throttle body fuel injection I also have a HEI distributor . It's technically made for the CJ but my guy at 4wheelparts.com said to get it instead of the howell conversion.
