Jon G. and Carb King, It is a shock to my pride but you need to know. I replaced the old carb on my 54-3100, 235. In that this is near the last of my AD restoration's I wanted it to be perfect. The new old stock carb which I have had for about 50 years was bought from my fathers store. Of course I rebuilt it (one of very many), but I cannot get it to stop running rich. This is the third set of new AC45's that I have put in it and after a 1/2 hour they foul out. Compression is great, valves need to be adjusted as soon as I can get it to run for a half hour. I flattered myself as being an expert but this old bugger has shown me otherwise. I always do the 600 grit sand paper on everything (air horn and fuel bowl), that I have rebuilt. Many satisfied customer's in the past but, I cannot get my own to run. HELP! Doc.
