Phoenix - 1975 Sears Suburban ST/16

Tomorrow, I'm going to see about clearance on the carb, I found an actual pulse plate the fits between the carb and head. If I have the space, I'll get it as it's only 9 bucks, but I have limited space in there. If not enough space, I can just make what I have better. Also, I may look into putting a set of new-old-stock blades on the tractor after today. Then I can resharpen what I have and put back in rotation.

OK, so the plate is actually a replacement isolator with a pulse fitting for a fuel pump.  I got it today and for 30 minutes ran GREAT.  Then for the first time the engine started running really RICH and fuel was coming out the overflow.  AYE.  Talk about fixing one issue to create a new. Pump now works 100% and pushes more fuel than the carb can handle.Looks like what I need is add a T connector between the carb and fuel pump running a line back to the gas tank. Not really feeling drilling a hole in the gas tank.  Not sure how to catch the shavings, plus getting it out is a partial disassembly of the rear of the tractor.  Or being very skilled.  I can do it.  Done it before.  

I am wondering if I could put another T between the tank and pump to feed the excess back in line?

Put a fuel petcock on the pulse line to restrict how much it actually pumps... works for me anyhow!
