Any one have pictures of a converted 25cc homelite wacker motor? I'm starting my first conversion and need some visuals. Thanks in advance, :)

Here's my 30cc Homie (externally identical to 25cc) with the stock flywheel. I had started trimming the crankcase and was probably 80% done as shown. I just received the Synchrospark kit I'd ordered from CH Ignitions. One of these weekends, I'll fire it up on the bench and report the RPMs.

this is the way I do mine...

The motor I bought (10.00) still has the machining on the cyl. walls and on the piston. The string in the shroud from the wacker is still white so I doubt it has much time on it. It did come without a crank case back plate though so I went back and picked one up. But after getting home I started to wonder if it should have been a metal one? It is made of black plastic and covers the whole back of the engine. But it fits quite snuggly into the engine so I cant imagine there being a steel one under it. Is the plastic one the only one there? Thanks

Some came with plastic, some with steel. Should be no problem. I have one that I converted and am just waiting for the electronic ignition to come in the mail. I'd send a pic, but I'm in the middle of moving and unhooked my scanner. These engines seem to work real well. www.carrprecision.com has pics and parts available.

Good luck,
AV8TOR

I have been very happy with the parts that I recieved from http://www.carrprecision.com/Pages/prod02.htm

I have 2 of the 25 cc units. Seems only problem is the compression is to low for them to start. Will they come back to life with new ring(s)?

I sold these a while back, but they are 25cc versions. Pretty easy to cut them down really.

I have tons of pics and specs on HOMEY converstions. Feel free to email me directly or go to http://www.rsengines.net/ to see where they all come from.

I would have preferred a pastic one. It would act as a better "gasket" between the aluminum plate motor mount and the crankcase. Plus it should be lighter than the steel one I have.

Thanks alot for all the response! The links and pictures are very helpful. Has anyone used a homey 25 in a Sig Spacewalker 2? Which aircraft would be a good first gasser?( please don't say a cub. I can't stand them. I had one and hated it. :( :disappoin )
Thanks again,

First Gasser
 

soulman,
for your first gasser I HIGHLY recommend the Sig 4-Star 120. It builds very easy and is IDEA for a 25cc Homey. If you want pics and spcifics of this set up email me or go to
www.rsengines.net

Two of those guys are building 4-stars side by side right now. I have MANY pics of them with gassers pulling them through the air with ease. I would be glad to give your all the information you need. Just let me know what you want.

Sincerely,
Flyguy2002

RE: homey pics
 

another great plane for a 25cc homey would be a lanier stinger 1.20 (see my link below...) it certainly isn't overpowered, but a great sunday flying type plane. (no 3d with that combo though...) VERY large and very noisy!

RE: homey pics
 

OK guys, I am ready to convert my 25 Homy to electronic.. from CH..

does anyone have pics of the before and after.. Mag removal and what do you do with the flywheel.. Hmmm

They say a picture is worth a thousand words...

RE: homey pics
 

Gene,
That is a beautiful conversion. Did you do that? Great Job!

RE: homey pics
 

Yep, that was my handywork. I figured after converting ~25 Homelites it was time to do one for me and keep it. It is a 30cc with a sandblasted, highly modified case/cylinder...components/mods include a velocity stack, big-bore carb/manifold, ported intake on cylinder, flow modified ports to cylinder, Frank Bowman high-compression rings, stuffed back plate, CH Ignition w/ Bosch cap, resistor plug, Bennett muffler. I plan on making a mousse-can-like pipe for it but model the pipe like an MVVS's mini-tuned pipe where the header length goes into the can about half way...that should give it a broad RPM range 'on the pipe'. Previous models like this one did ~8300 RPM with an APC 18x6W prop and Bennett muffler...they weren't even broke-in either. I'm thinking this one will turn in the low/mid 9's with the pipe and that prop. FWIW...I got it all finished and haven't even started it up yet. I've got a NIB Balsa USA Stingray 120 kit I plan to put it on.

...Too many toys and not enough time to play with them all!

RE: homey pics
 

This is a 25 I took it out of my plane and have a 30 on the way(I found a place were i can get just the engine on its own for a reasonable price). Does anyone have a rough idea of the difference in power between the 25 and 30.

RE: homey pics
 

Get a backplate mount cast in aluminium by AJC
they are wonderfull and light
not expensive and beautifully made
Andrew Coholic is on line regularly

I have 2 of his Great

RE: homey pics
 

Look for a small hole above the exhaust port. If there's one there it should be plugged with a set screw. The compression will go up considerably. Once you get the technique down, these engines are really easy to start by hand. Prop should be in about the 12 o'clock position.

Jim

RE: homey pics
 

I have both, and can't see much difference in power.

Jim

RE: homey pics
 

I dont suppose anyone has tached both with the same size prop for a comparison.

RE: homey pics
 

Ok, I see a couple of nice engines.. but how to remove the flywheel??

Floyd

RE: homey pics
 

Hello,
First remove the trimmer drive shaft adapter nut by turning it counter clockwise with the flywheel clamped in a vise or otherwise restraned. Then use a gear puller or a large flate tipped screw driver placed between the cooling flange and the wheel. Pry a little on one side, then rotate the wheel 180 dgrees and pry again. Repeat this until the wheel is free. Do a search for homelite conversion on RCU or in Google.

Dave

RE: homey pics
 

Thanks Dave, I am sure the wheel puller is the best choice...

Floyd

RE: homey pics
 

Dave, got it off.. now am installing the CH ignition..

Couple of questions.. I have the short adapter for the Homelight 25.. the adapter is 1 1/2" long and the threads inside are 1".

The crankshaft on the 25 is 1 1/2" from the bearing to the end of the shaft.. and the threads are 3/4"..

If I install the adapter there would be no threads to bolt on the prop...

Do I cut off some of the crankshaft ??? or get another adapter from CH ignitions...

Floyd...

RE: homey pics
 

Hi,
It sounds like you got the wrong adapter. Usually the body of the prop hub has 5/16x24 thread al the wat through. The shaft screws in the engine end and the prop bolt and washer screw in the other end. The tapered keyed section either holds a flywheel or a magnet timing hub. The Hall sensors that I have seen on Homey's have been retained by a small hose clamp. You should giv Bill at CH a call. I'm sure that He can fix you up.

Dave

RE: homey pics
 

Duplicate reply.

Dave

RE: homey pics
 

do you have a short or long crank shaft. If it is the long you will need an adapter that is not threaded at all .

RE: homey pics
 

DID YOU FOLLOW THE INSTRUCTIONS???? Especially the paragraph that says that there different length prop shafts and that you should cut the crankshaft so that it goes in the hub half way and the stud the other half.

RE: homey pics
 

Thanks Dave3, will do that...

Floyd
