Tanaka Engine

Howdy Matrix Master,
Does your engine look something like this one? If so I have the manual somewhere around here and can take a few pictures of the manual for you.

View attachment 649068 This engine was part of a 2/2.5" Keene suction dredge I purchased back in 1992. It is a good engine. I have to find the instructions to get the gas/oil ratios. I will get back to you.........63bkpkr

That looks like the kawasaki engine they used for quite some time but the Tanaka is quite similiar looking also and no oil. They used TML radio controlled airplane engines from canada for awhile also. John

Hello Again mmDBA,

The short answer to your question is two cycle engine oil that is made to mix between 25:1 and 50:1. Of course the pictures of the manual explain this a little better but Tanaka likes the 25:1 ratio. Also note they give a warning to not use Gasohol, like we have a choice these days. The manual is about 30 pages long, with all the languages its printed in, so if you can use a copy of it let me know.

Best of luck.......63bkpkr

And howdy there Hoser John! How goes it? Well I hope! This week will see me working six days, five ten hour days and one eight hour day and then Sunday and Monday and Tuesday each for 10 hours and then off for five days. Wish I was going to do something wonderful with those five days off but that will depend on if my Son and I are able to get together. My knee is still acting up so I've an appointment to see an Orthopedic Surgeon. Ain't that a pain!!

WOW Herb it sure sounds like that new job is really working out great and truly hope that knee gets better through by trying some some simple physical therapy and NOT the knife. Saw my knee doc Schwartz the other day and now that he has a $7 mill new office he wants to cut on everybody who steps in the door!! 2 hour wait,11 patients and all going under the knife EXCEPT ME. Had 3 ops already and pt did much more good than all 3 ops-err on the side a caution and hope your outdoor passion will resume asap and nuttn' but respect ---tons a au 2 u 2 -John
