Having some difficulty setting my timing using a vacuum gauge on my 48 New Yorker 8 cyl…..and could use some guidance. I’m trying to find the timing “sweet spot” rather than just rely on the book specs. I’ve attached my vac gauge to a non-ported vac source at the carb base…(it usually reads about 17-18”)… then adjust my idle as low as I can get it…about 350 rpm or so….to keep the mechanical advance from kicking in. Did not disconnect vacuum advance because it is not supposed to activate at low RPM. Next, the procedure is to advance the timing until you get the highest rpm...just before it drops of. The problem is the more I advance, the more RPM I get…until I can’t turn the distributor any further (about 12-15 degrees (which I know is way too far). What should happen, is that at some, point the RPM should decline when the timing is too far advanced…but it doesn’t. I would expect the RPM “fall off” to show excessive advance, but that’s not happening….(FYI, points are set to specs and read about 28 degrees of dwell). The manual calls for 2 degrees ATDC, but with modern fuels I’ve been told most people run about about 2-4 degrees advance; I’m currently at 2 degrees BTDC based on my timing light. Can anyone tell me what’s going on?

Any old timers willing to help a noob with a little tune up. I recently bought a 1946 business coupe off of my Grandpa and got it out to California. The car runs but will die and then is hard to start plus is running a little rough any way. The car has sat for about 12 years but it fired right up and I have been able to drive it some. It needs to be a little more reliable. I am mechanical but this thing is new to me and would love a little help and to get to know some locals with the same car. I am located in East Pasadena.

so i have my old 1950 dodge b2c and im rebuilding my engine well making it look new again and painting it and cleaning it in the process i am pulling everything apart cleaning and painting things when i took off my distributor i realized that my Vacuum advance on the distributor isnt working i pulled it off and sucked on it surely enough nothing happened and i already rebuilt my distributor and dont feel like buying a whole new one were can i get this part? i went to 3 [parts stores and they had nothing. im hoping this will fix my trucks running issues thank you ! ill [post before and after pics of my engine later for all you interested it looks beautiful for only spending 200 dollars spiffing it up and some elbow grease -
Hi Everybody, I have a misfiring problem on my D22. When the engine is on higher rpms i have a misfire so the car wouldn't go faster than 45 to 50 miles. It also has not full power on full accelaration. First I thought it was the braker, so I installed a new on, including finger, distributor cap, wires and spark plugs, but it didn't solve the problem. Then I tried an electronic ignition but it won't be better. Then I thought it may be a fuel problem and rebuilt the carburator but nothing happened. By the time I installed a new carburator, new fuel pump, new rebulilt distributor, new fuel filter and checked vaccum and all that stuff. Now I run out of ideas. When I check timing it seems to be everything ok but the marks jump a little bit. Then I remenbered a post, that I didn't find anymore saying it may be a problem of a worn timing chain that could affect the timing in higher rpms. I'm not sure if this could affect the misfiring in higher rpms. Did anyone heard about that or have another idea? Thanks a lot Kai

I got a 48 Plymouth with a 218. Last night I wanted to check the timing because I kept thinking maybe there was something wrong, running like it was very retarded (no pun intended ) I loosened the distributor and removed the vacuum line from the carb. I plugged the hole in the carb to delete the vacuum leak. Started the motor (RPM around 450-500) and checked to see what was going on at the crank pulley. I couldn't see much so I shut her down and cleaned the the pulley to get a good visual of the timing marks. I started up the car again and got to work. I could see where it was set so I started to make some adjustments. After turning it CW and CCW a few times, I noticed there wasnt much or any difference in the sound of the engine. So I drastically turned the distributor CCW and CW with no audible or RPM changes...very wierd. I shut the car down and checked the vacuum advance unit. I sucked on the vacuum line and it appeared and felt like to be working good. I know its not working while timing, but sometimes you think of the darndest things. With that good I fired the motor again and messed with the distributor again with no changes. Very wierd...no sputtering or speed up of the engine rpm.... NOTHING! Any Suggestion to the issue im having? Is this normal? Im thinking I have a 'bad' distributor....weak springs maybe...I dont know...im "spitballing" at this point. Thanks for any help!

I am trying to get my 47 D24 started! It sat for 20+ before I got my hands on it. Replace plugs, cables, coil, condensor, distributor cap and rotar, battery and cables. I am pretty sure I have the plugs set right but I can't find the timing mark. (too rusted to see it) Any suggestions????
