  1. 41, Perhaps I am misunderstanding your statement, but I am not running a Pertronix module, just their coil. Rod
  2. Thanks Terry, I'm just playing around trying to see what works and what doesn't. The wires and rotor appear to be fairly new. That pertronics site is a little confusing with their charts etc, which is why I asked the question. I'm going to play with this a bit, changing plug gap trying to find a sweet spot. I bought an "innovate LM-2" exhaust gas analyzer recently in an effort to dial this thing in, but with only an end of tailpipe sniffer it isn't steady enough to do much good, might have to weld in a bung further up the pipe for the O2 sensor? Rod
  3. I'm a little bored so I checked the plugs and found all 6 to be set at .020 I reset them to .025 resulting in some improvement. Then I got to thinking about the coil. I have a "Pertronics" # 40011 1.5 ohm brand new in the box. can I use it , or am I better off using a 3.0 ohm? Rod
  4. Castricum, sorry but it has sold. I do have two other Model A's, both in excellent condition. Another deluxe coupe (1930) with rebuilt engine, transmission and rearend. $27,000.00 And a 1930 Phaeton that is like it just rolled off the assembly line $28,000.00 Both have just been color sanded and buffed to a perfect shine. See below
  5. Well I received the new carburetor and installed it today https://newcarburetors.com/?product=y200-universal-carburetor This is a new, not rebuilt unit. Straight out of the box, the car started right up, I adjusted the idle mixture using a vacuum gauge to 60" max it has about a 2" intermittent drop. 58-60-58-60.... The prior issues: intermittent miss, stumble and near closed choke requirement are all gone, so I think I was was right about the Carter w1 being defective was correct after all. Lots more power than originally but some of that increase is probably the result of my adding
  6. Ed, I am pretty certain there IS a vacuum leak in this carb. I have totally isolated it from any other source of a vacuum leak. the only connections to it are the fuel line and the throttle linkage. Using your "propane" test I get no reaction at the gasket between the carb and manifold or any where externally, but when the engine starts bogging down and I apply the propane to the inlet, it immediately levels out and runs great. The same reaction as choking it. We are not talking high rpm's or no more load than coming off idle up maybe 50-75 rpm while parked. it seams to me that adding th
  7. Yes, the lean condition is what I've been talking about for some time now and that is why this carb is going back and another one is on the way. When I ordered the intake manifold gasket, I also got the exhaust manifold gasket, I think the ports are the same, so those exhaust gaskets should work in the intake ports, if so, I might put the marvel back on and see what it is like with the timing advanced. (just for shi.. & giggles). My conversion to the down draft is not set in stone, but i'm a stubborn old fool pretty intent on seeing something through once I start it.
  8. Thanks Larry, Geeez, could they have not have found a more perfect spot! So far here is what I am finding on the engine. 1. Checked the battery and coil voltage: Battery = 6.09 Coil = 5.91 so some voltage loss there, don't know if that is significant? 2. Advanced timing ~ 3* (a guess) Engine likes that with power increasing but still requires choke only open about 3/8". 3. used propane in the intake of the carb as per Ed's instruction and the stumbling was somewhat reduced, so there is a vacuum leak somewhere. I had already disconnected all the vacuum connections and
  9. Thanks guys for the new comments-suggestions, all are appreciated. I have been tied up with a wet sand/buff project on one of the "A's" and hope to get back to the Buick today - After Voting of course! Rod PS Where exactly is the inspection cover to view the timing mark on the flywheel? I'm looking on the distributor side and see nothing.
  10. Thank you Ed, Grimy, And everyone else who have offered constructive advise on finding out why this engine is misbehaving. I have made a list of all the suggested items to check. This is going to take some time and I will keep posting findings as I get to them. First off though is the down draft carb. I need to figure out if it is also misbehaving as it only has a 60 day warranty. This morning I replaced the intake manifold gasket as well as the carb to manifold gasket. I checked (starter fluid spray) at all the suspected areas for a vacuum leak. I didn't detect any. I took the car for a
  11. After reading all the posts in this thread I think i need to reiterate what exactly has been the issues with this engine and i'm going to do it numerically in the order in which they occurred: 1. Bought the car in March of this year. 2. Noticed on the 1st drive that there was a noticeable lack of power in all gears at all rpms. There was NO missing or back firing at this time!! It did run really rich. 3. Read of the possibility of reversing the manifold and using a down draft carburetor because multiple people were reporting issues with the Marvel. (at this time i knew noth
  12. Well, unfortunately myself and a good number of the rest of us don't think so highly of ourselves and just keep stumbling along hoping that a question we might ask might be reasonably answered without being dissed as ignorant fools. I'm sorry I started this thread. Rod
  13. I really don't want to push this Marvel switch controversy too far, but here is something to contemplate for the future (maybe sooner than expected). If no one steps up or is qualified down the road to work on and adequately repair the Marvel carburetors, then what will be the answer. It would seem to me that without a means of repair everyone including the "purest" will be forced to go with something other than the Marvel or maybe it is their intention to create a knock-off "Marvel"? Can you imagine the cost of that item, I should think pretty cheap considering the huge demand.
  14. Grimy, Finally someone with some actual help, thank you so much, it is much appreciated. No the stumbling, miss and backfire that is occurring with the Carter down draft, did not occur with the Marvel. The Marvel equipped engine just had very low power and as I mentioned in another post, the model A's I have are much more peppy. I hope to get it out this weekend to see if my changing the intake manifold gaskets made a difference. Again thanks for the help and for staying on topic.
