The 706g is Going Again!

OK, as you may (or may not) remember, I bought a 706g at an auction a few weeks ago. I had to get the radiator recored, but I expected to find a few bugs.

I got the radiator back today, put it on and ran it for a while and it didn't overheat or leak, so I am pretty happy about that.

It was running sort of funny and weak, so I pulled the plugs and the first 4 looked good, but the #5 plug had the electrode mashed in so there was no spark at all. I bent out the electrode and reinstalled it because all the plugs look good.

It runs very smooth compared to how it was running. It revs smoothly and lugs well. It runs cool and starts great.

I am looking at doing a tune-up (coil, plugs, points, condenser, wires, rotor etc...) and an oil change since I read something on here about low-ash oil.

Finally, I am worried about this 93 octane business. I was able to get 91+ octane from the co-op for my farm tank and I don't plan on working the tractor very hard. Maybe plowing/discing a couple acres per year and running a 6' bush hog. (I know, I don't really [u:3dc599824f]NEED[/u:3dc599824f] a 706)

Is the 91 octane going to kill this engine since I am not going to be pushing this tractor a lot?

Thanks for the input.

You should be ok if not going to plow with it.
Use only the low ash oil though.

The M+R method of rating Octane will allow 91 R+M to be as good as 93 Research. It appears you have a great tractor. Jim

One more question:

Where can I find the correct hose that goes from the air filter tube to the carb inlet? It is a short length that is almost a 90 degree angle. I can't find it on Steiner or Bates websites.

Thanks.

CaseIH probably, but a trip to the napa radiator hose rack will probably find a perfect solution (possibly cut out of a more complex hose, but cheaper) Jim

There is one little trick that you can use if the engine pings intermittently: richen the carburetor mixture slightly. Of course people tell you about retarding the ignition timing but beware--that can cause exhaust valves to overheat--especially under the occasional heavy load. A slightly richer mixture can be done or undone easily without significant risk of engine damage. Just sayin.'

Matt,
Where did you get the radiator re-cored and how much $ I think I might have to do that also.
