just did compression test, all the numbers are within 5psi of each other ranging from 125-130psi.
as soon as i get some numbers for what others are running in their DCOE40's I'm going to order new internals, AND new plugs. I'm super irritated with this whole damn thing.
advancing and retarding is not changing anything at this point, and adjusting the mixture screw i get to where the plugs are no longer fouling, BUT at this point all the carbs have about 1/8th of a turn left on the mixture screws, and then they are fully closed, at that point it doesn't could the plugs, BUT it also will NOT idle at all, if i keep tapping the pedal it will run, but as soon as i let off it shuts off, I've even tried re-syncing the carbs at this point and bringing the idle up, but it does not stay running at all. if i go back to baseline on the mixture acre (1.5 turns to start with then adjust from there) the car starts fin and idles ok, but will not drive, just pops and sputters, and fouls the plugs.
at this point, I'm jut going to set the car on fire.. no wait, thats not what my plan is, I'm going to order the jets that are suggested to me. I've messaged Kev, but no reply yet. he sent me a good set of numbers, and i did NOT make the order, i just tried rolling with what my carbs came with, and that was ok last summer, but now i can't get it to run at all
Sorry I didn't reply earlier, tim, been sick as a dog all week
As for jetting, as long as it's 40-something (F8 or F9) on the idle jet then it's close to the money. For the remaining main/corrector sizes, something like a 125main and 175 corrector would be pretty good. So your current jetting isn't that far out of whack (it seems quite common for Japanese webers to be set up a notch on the rich side) and certainly wouldn't be the cause of your problems.
The E in the NGK plug is AFAIK, just to denote that the electrode has a groove in it, and the non-E ones have a plain flat end. 11 means they are pre-gapped to 1.1mm which will be too big for points though, you need more like a 0.8mm gap.
Have you checked the state of your leads? Measure the resistance from end to end with a multimeter, none of them should be more than say 20 kilo ohms.
No Kev, you are eating a duck fetus.
