Subject: 503 Problem From: rayw (rmwis@charter.net) Date: Wed Nov 18 - 4:18 PM Hello, I could use some help. I am running out of idea's. I have a 503 with dual Bing 54 carb's. The engine starts and runs well up to about 2000 RPM. After this RPM it has nothing left it just bogs. I have gone through both carbs so many times I could do it in my sleep. I don't think it is fuel pump problem because I have rebuilt it and I have used the primer bulb to try to compensate for a potentially bad pump but this has no effect. The other day I ran it up to a point just before it bogged and put three fingers in front of the inlet of the right carb and got it to bog. I put three fingers in front of the inlet on the left carb and got a 1000 RPM rise. The carb on the left is an older type so I bought a brand new carb. Would you believe it? Same exact reaction. I went through the timing but I will probably go through it again to double check. Any body got any idea's? I have done so much that I can't even remember it all. Ray W.
