I did that. These plugs have 1 ride of 20 miles on them before they fouled up. Cleaned with the plug cleaner and have swapped plugs with the old plugs and back and forth etc same result.

I lowered the needle to the first notch and it did get hot on the left cylinder and much less fuel/oil came out.

So frustrating

Could be the fueled up side carb has a dodgy float or float valve needle , flooding. have a good look at the float operation, new floats sometimes have left over flashing seems that can catch and prevent proper closure, needle seats can have dirt on them and prevent proper sealing, that sort of thing.

Gavin that was the side that I checked the float level with the new style floats after reinstalling them and it was right on the pip. I was having issues with the new style as they seemed to be slightly larger than the old style and were getting stuck on the screw boss causing flooding and fuel to spit out the tickler. I removed the injection flash from the float and relieved a little material from the screw boss and that allowed it to work properly. At that point the fuel level was checked and it was on the pip.

I cranked out the air screw and set the needle to the top notch and it seemed to get heat into the cylinder but on idle there was fuel/oil coming from the header again. I'm going to pull that carb off and tear it apart, maybe something got stuck somewhere. I may swap everything over to my other 389 body and see if that helps. If not head will come off and see what I find. Based on my compression and leak down test I don't think there are any issues with anything but the carb, but I'm running out of things to look at.

Anyone know a competent mechanic around the Oxford, MI area? or Metro Detroit? I know about E&V but I'm looking for someone within an hour or less and hes 3+. I'm getting to the throw the towel in point after 2+ years of restoring and 3 years of trying to get it to run right I'm about done dicking with it. How reliable are those repop concentrics from AMAL? maybe I should switch to those.
