What I Have:
1974 Eska (Ted Williams 7.5HP) model number 217.58882 with carburetor type 640-09 Spark Plug Champion RJ12YC
The Problem:
I can connect the fuel line and prime the bowl using the bulb. Fresh gas mixed at 32:1 with Walmart TC-W3 premix. If I disconnect the fuel line and pull on it about twenty times it will fire up and start running. I quickly shift to gear and put it at fuel throttle. But before it runs out of fuel I reconnect the fuel line. And it runs horrible and wont idle. Only when I disconnect the fuel does it run well.
What I have done already:
*Fresh Plug gap set to 0.030
*Thoroughly cleaned carburetor. I took everything thing out, carefully inspected all the gaskets. I had to cut a new engine/carb gasket out of rubber fiber gasket material. The fuel diaphragm and the orange pump thing are in great shape. Sprayed carb cleaner in everything and blasted out with compressed air. Put it all back together following the Tecumseh two-stroke book. Setting the float to 11/64". (The original brass bowl bolt was torn, so I had to get a new one made, everything is identical with a 30/1000" hole drilled at the bottom. Is that the correct size hole? We didn't have much to work with)
*Checked the spark using a small engine spark tester and I have no problems with the ignition whatsoever.
Does anyone have any advice as to why this motor keeps getting too much fuel?
Thank you,
Chris
