Earlier this year I was set on buying me a new Stihl mini tiller to Replace my Honda mini tiller. Well the way it worked out some guy was moving out of state and sold me a like new craftsman mini tiller for cheap cheap cheap 8). Works great and wife loves it.
The other day cruising CL I seen another one down the road from me for $20 and stated locked up. I'm thinking cool parts for the one I just bought.
Well today I was looking at my JD trimmer that is a Homelite 30cc powerhead and I thought to my Redneck self, I can do this. ;)
Here is some pics of the parts mini tiller with laminated crankshaft throws. The rod pin had oblong the crank and finally broke the lamination apart. The muffler had some kind of metal wire coming out of the exhaust outlets and was plugged up (forgot to get pic of that). ???

Nice engineering! 8) 8)

The First torn up engine is a Ryobi and so is the Craftsman engine on the original good tiller
What do you think of that stamped steel fabricated connecting rod?
-
You remind me of myself sometimes!
My neighbor is still running the Stihullochobi string trimmer I "repaired" for him years ago.
Took some "engineering" but it worked great.

The Homelite 25 and 30 were far superior to the Ryobi 31/32 engine.
-
Hey hey hey ain't a thing wrong with a chicken wire bubble gum fix .Been doing it all my life . ;)
-
I'd be willing to bet that your wife takes to the one with the Homelite engine and the other one just sets?
-
What do you think of that stamped steel fabricated connecting rod?
:o and that laminated crank ::) Cant believe it when I seen it.
Testing the Homie one out she says it tills just like the other one. Thats all I care about right now.

I have some of those Ryobi engines and they run OK but they don't look so good to take them apart.
I have a Ryobi from 1985 that was originally a Lawnboy. I used it as a weed whacker for 15 years and it tired me out many times. It stihl runs like new as a model airplane engine. If you do anything to one to make it run faster, the rod big end will give trouble. You have to keep them below 7000. Some even had limiting coils at 7000. The one I sometimes currently use as a weed whacker has a limiting coil in it. The limited coil is OK for weed whacker use.
Even the Homelites have changed. The original Homelite 25's had a forged crank with the counterweight and main shaft as one piece. But since the early 90's they have been a piece of drill rod for the main shaft and cold rolled sheet for the counterweight. The crankpin always was drill rod.
A interesting observation on my part is that all the curved shaft type weed whackers use the .080" trimmer line and the homeowner straight shaft ones use .095" line. The reason is that the straight shaft ones have a gear reduction in the trimmer head. The 095" line lasts a lot longer.
My cheaper Ryobi and Homelite Bandit weed whackers have no clutch and are direct drive to the string head. I get along just find with them this way.
My Stihl 45 curved shaft trimmer has a clutch. I like my Echo yard tools the best. The Stihl 27cc engine has good power but the ergonomic feel is not as good as the Echo.
The newer Ryobi branded engines are the Homelite design
-
Everytime I see the internals of some of these engines, I can't get over what I see. But, I guess they are building them to a price point..
-
Actualy some of the Echo stuff works pretty good .I have a couple of hedge clippers and an Echo weed wacker .The wacker does better than a Stihl of the same size displacement .
Funny story on the wacker which I got at a garage sale .The man couldn't keep it running and it nearly new .Tear in the fuel line which I had running in five minutes and cut some weeds for him .I remarked after that fix he probabley didn't want to sell it .He said it's okay and dropped the price to 25 bucks just for the lesson on small engines . ;D

I just had a mini tiller dropped off. Guy on phone told me echo, when I seen it not.
Somebody in the past had his degree in redneck engineering too. Pics to come later.
-
My Echo tiller has the power head mounted by the snout just like the rotor tillers you had.
-
Rednecked mini tiller. I really like the 90 degree exhaust outlet idea.
Any clue what cc the homelite trimmer is?

That style is either a 25cc or a 30cc
30cc is not so common but I was thinking we decided it was a 30?
-
Does it have a clutch? My experience with homelite is 25cc direct, 30cc clutch
-
Homelite ST-145 IPL shows drum and clutch http://www.searspartsdirect.com/partsdirect/part-model/Homelite-Parts/Grass-trimmer-weed-wacker-Parts/Model-ST145/1518/1503820
-
Found 3 listed. HOMELITE ST-145, ST-155 and ST-175 with no specs
-
Well looks like I am looking for another motor for the one on the right. The laminated cranks just cant take real garden weeding work between rows. It quit and then rattle when try to restart. Finally locked when a part moved just right. ;D
If you got a trimmer motor you think will work let me know. I have a few listed from before.

Thanks Jim for the delivery of Mac and Ryobi trimmers. The one Mac you seen get to run that I said I could redneck to work was a failure. I ended up ruining the recoil shortening it up as far as I needed to reach the tiller shaft. strike 1
So I dig back in the Ryobi PH that had broken recoil. Another no go after removal. The whole bottom end is totally different then the Ryobi tiller motor one. Couldnt believe that one. So went to try and do a switch and got all but 1 seized bolt out.
Time to walk away and come back later.
Thanks again and enjoyed the small talk.

Tomorrow is another day . . . .

Got another craftsman tiller with ryobi motor. I had gave some hardwoods off my land to a guy for firewood at my dads church. He ask my dad if he had a use for a mini tiller. My dad got it and I remember tuning it last year or year before for another guy he gave it to. Well that guy told dad he hasnt used it since last year and he could have it back.
Just finished giving it a fat rich tune and see if that helps hold them stamped rod and laminated crank together. :-\ ::)
-
I have another Ryobi whacker if you have to have one. I don't think it has a clutch?
-
I'm good for now and should get through the garden season.
Anyone every paid attention to the rpm a weed trimmer is turning at WOT trimming?
-
7000
-
7000
Hmmmm that last ryobi tiller was turning closer to 9K and was pretty fat after I adjusted it down. Maybe that is the issues on these. All that have came to me was 9plus from factory. Except the one I couldnt check as it had already **** the laminated crank.
The one I just did is pig fat at 7800
-
The model airplane guys have always said that if you turn a Ryobi past 7000 for any length of time, you are going to loose the crank pin.
-
I have a Craftsman tiller like this one.
Never has ran right, I think air leak..
I am thinking about adapting a saw engine to the tiller.
What do you think?
-
Please show how you adapted it please.
I have only found certain weed eater heads to work so far without modifications.
-
I am still in the thinking stages.
Not sure if I should use a Poulan or a Husky 235?
-
LOL at PB blackmailing folks for $. They can pizz off IMHO blocking folks pics. ;)
Just rednecked another mini tiller with the homelite trimmer I bought yesterday. Now just 1 more PH to find. Hate those ryobi motors they put on these.
-
Started on that other ryobi motor one on right yesterday. Never did like the zama china carb that was on it without a choke. Had some kind of knob on side like you turn for choke. Reminded me of the i domars carb deal.
Anyway switched over to a walbro carb and a choke set up I had from one that had blown up years ago. Flooded it bad on 1st try so waited till today after pulling plug and pulling through yesterday.
Got it running and tuned, So will be #3 till that laminated crank lets go someday.
