Just came across you forum, thru MTF site. My 318 is doing exactly the same as tjoltz was. I cleaned the carb, new plugs, points and condenser while i was there. Still same result. Surging up and down. I didn't repair the rivets intake, was going to but thought i could get away with it. All that said just wondering what happened with his. Hoping that it's not the governor. would be nice if it was fuel pump issue or something like that.
Also have creeping issue, won't stay still if last in forward it rolls forward. In reverse the same. is this an adjustment or repair?

Im going to start with the creep issue as its the most clear cut to deal with.
Most likely the linkage is loose or is worn at the pivots. Youll need to remove the fender and try and trace and remove any sloppiness between the forward/reverse lever and the transmission input lever.
Eliminate that and set your neutral and all should be well.
As to the surging as you know it could be many things. I would first eliminate the fuel pump/filter/tank by employing a small pony tank and run the tractor of of that for a while and see if things improve.
I use a small 1/2gal tank scavenged from another piece of equipment and brace it up on rods so the fuel level is about 1' above the carb to ensure good flow. Also use a new section of fuel line from this tank to the carb to eliminate any obstructions or leaks.
Using a plastic tank mounted above the battery works well. Make sure to not let it come in contact with the battery terminals!
If this does not clear up the issue I would look to the intake manifold and gaskets next. I may have a manifold if you need one replaced.
If its none of the above, look at your governor linkage for wear or looseness. Sometimes you can add fine springs to the linkage to take up the slop if it is worn.
At thin point you would be down to looking into the governor itself.
Keep me posted with your progress and Ill help any way I can.
