Tanaka P7 engine parts including the Keihin carburetor are very very hard to come by. You might consider getting a replacement carb but you will probably have to get/make an attachment collar. I also suggest joining the FB Little Petro Group

Brandan It appears that your engine is a general purpose TAS motor with no gear reduction/transmission.. I see that on of the stickers on the cover says P-7 and the other says P-72. It also looks as if this engine rotates in the opposite direction of (2) TAS P-7's I have. I do not know if this motor could be used for a minibike. I state that because I use TAS P-7's for minibikes. Maybe you have seen pictures of my P-7 up in this string of posts. Are you interested in selling this motor and parts ?

My damaged float and the carburetor pics are about 5 posts above. Thanks for the eBay link for a float. I purchased it but the seller couldn't give me accurate dimensions. Maybe I will get lucky --

HELP PLEASE - I need a Little Petro P-7 KEIHIN carburetor - OR a carburetor float. I have tried many other floats that do not fit in the KEIHIN float bowl. I have been looking for over 1 year now and I really need some help with this --- Help. I can also be reached at hkillackey@aol.com

I had a few Tanaka P7 Air Cleaner Covers made. I have listed them in eBay. They came out very good. They can be gentle sanded if you want to make them show quality. https://www.ebay.com/itm/164645598092?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649

Yes, That is the next step if I can't get another spring. I will apply a clamping vice-grip about 1" from the end of the spring. This will act as a thermal shunt heat dissipator. I will then heat the spring end to red/white hot if possible. This heat treatment will remove the hardness spring of the steel. It will be easy to form the soft steel. After forming the soft steel end heat will be applied to a blue color. This should restore the hardness of the steel to a spring. I know that one or both heat treatments will require a quench in oil or water.

The curved end of the spring coil is gone. I believe it broke off at some point in it's life. I don't know if my Tanaka is a match to the O&R. I do believe the pull stater design is similar but I don't know if the Japanese Tanaka did a 100% design copy.

Hello - I need a pull starter mechanism for my Tanaka P-7. I don't need the engine cover that holds the pull starter mechanism but I would be willing to buy the cover with the pull starter mechanism attached. My internal spring's tab that retains the spring has broken off.

Hello - I need the Pull Starter mechanism for my Tanaka P7 motor. I would love to have the engine cover with it or even the whole engine..... If possible. I need some parts help to get my old Tanaka running again --

On my old TAS P-7 I had to re-tap the threads to a modern/today standard metric thread pitch. The JIS metric thread pitch of 60+ years ago are similar but not the same as today. Get the M diameter size and a new tap and chase/reform the old threaded holes if you are going to us new M fasteners

Hello - I need a TAS Tanaka P-7 or P-5 engine and carburetor. I also need the plastic air cleaner that was on the carburetor of the old P-7.

I looking for ANY parts OR whole motor for a Tanaka P-7 or P-5. I need a carburetor also. I have a non working Little Petro that I want to restore.

I need a Tanaka P-7 motor ..... for my Little Petro project.

My engine before assembled to frame

I have started a Facebook group specific for Little Petro's. You can join the Little Petro Group and we can learn, trade, find info about obtaining parts, share photo's & etc. Do you have a better Coil Cover than this one that you would like to sell? Mine shown needs a repair around the wire hole.

Very Interesting ...... I might have Little Petro transmission ..... I'm not sure of the condition ..... the motor was torn apart and the motor orange painted cover was damaged. Also - I have just started a Little Petro Group on Facebook as another source for getting in touch with other Little Petro owners and fans. On Facebook search Little Petro Group

I didn't / couldn't find any Little Petro plastic parts (Seat, Chain Guard) ---- So I have made a few for me and Im selling a Seat & Chain Guard on eBay now. in 2020 I will be making the Little Petro plastic coil covers...... since I can't find / buy them.

Yes, Im selling a few Little Petro Seats & Chain Guards on eBay now

Craig, Can you email me at hkillackey@aol.com thanks

Craig H, Hello. If you can sell OR loan me your chain guard I will have a solid model made and a few produced. Please respond to me - Hkillackey@AOL.com Also - Is the chain guard like this one ?

Just a FYI. The chainsaw has a Tanaka P-7 engine. The guy on eBay that sells the engine decals made them say "P-74c" so nobody would copy/steal a picture to make their own. The problem is that when you buy on from him on eBay you get "P-74c" and not the correct "P-7" as produced by TAS. I know because I have purchased 2 sets -

Your welcome Clint. If you come across any Little Petro plastic parts such as: Seat or Chain Guard please contact me here or at hkillackey@aol.com Any part I can buy might be a better starting point for my mold making than my current plan

For my P-7 engine in the photos that has the small diameter Spark Plug (10mm major thread diameter) I use NGK CMR7A. For my other P-7 engine that has the large diameter Spark Plug (about 14mm) I purchased Champion CJ14. Since my usage will only be a few times a year for maybe 5 minutes it really won't matter ... It's not like the engine(s) will be raced or held at 90%+ RPM's for any long durations.

P-7 engines came with small & medium diameter spark plugs. I have 2 P-7's and the heads & plugs are different. I went down to an old lawn mower / weed wacker repair shop and he had the plugs.

It was media blasted. Im not sure with what exactly - and It's a TAS P-7 Here's my resto-mod today. You can scroll up above to my April 2018 post and see the before picture. The chain guard mold will be made this summer 2019 - then copies. I will later in the year make the seat mold and copies
