I am getting some of the necessary parts from wackerengines. He does not have a mount for this engine. I have the motor on order and have not seen it yet, however, I have seen pictures from wacker. I am lost as to how I would mount this engine. There does not appear to be any mounting area available in the rear. It also appears that the case would protrude out, preventing the use of the case mounting holes. Any help with this would be appreciated. Also, I have seen a company called rs engines mentioned on a few posts, I cannot find their website, does anyone know what it is?

Most often the big part of the crank behind the engine is sawn off. It has to be done in a manner as to not get the seal hot.
They've been using the H9 Ultra Stick mount but it doesn't just fit up alongside the engine case bolts. They make little aluminum adapter plates that extend out from the engine case bolts enough to bolt onto the H9 mount. There are other big mounts that will work also like the biggest Dubro.
There has been talk of turning the crank around in the block when using a C-H ignition assembly and using the oil pump screw holes to mount the Hall Effect sensor?
I have not converted mine yet.
Enjoy,
Jim

Well, Cummingstools came through town yesterday, so I picked up a Homelite 45 for a good price. Got this much done so far. More later.

Looks lilke this is going to be a fine little engine. Cranked right up this morning with the first tap of the starter. Didn't even have to adjust the needles on a Bambula 18x8 which it turned at 8400rpm with the stock muffler. I know that's kind of a small prop, but I wanted to go easy on the motor until I get a couple of tanks through it. I did have to richen it up a little with a Pro Zinger 20x8. Looks like the Ultra Stik is fixing to get a major horsepower increase!

Alright, three more flights today with the 45 in my Ultra Stik. I had three flights last weekend with the stock muffler and the landing gear off a Wildhare Edge on it. It flew fine, nothing to get excited about though. Today I was back with the stock landing gear (with 1" spacers installed) and a B&B muffler. One pound one ounce lighter (the stock Wildhare landing gear weighs a ton)
MA 20x10, 7320rpm and a Pro Zinger 18x10, 7710rpm. Unlimited vertical with either prop, hovers at half throttle with the MA. That's chugging along pretty well for a motor with 7 tanks of gas through it.

Is that the new style 45cc which I hear is harder to convert??? Something about there being a new way of the carb mounting that makes the conversion more difficult.
Thanks,
Steve

flipflop,
Is that the Hangar 9 large universal mount that you're using? I just ordered those for my Homelite 33s.
Here's how I cut down the bottom crankcase and rear crankshaft on the 33cc, which is similar to the 45, I believe. I left about 1/2" of the crank sticking out (I don't like to cut too close to the bearing). I made my adapter plates from 3/16" thick G10 material.

That's the new style 45 that you have to make the carb adapter for.(shown in the first picture) It's easy to make the adapter (if you have a lathe) because the intake stub is round instead of that weird oval shape like on the Poulan 46. Those are the Hanger Nine mounts, I do a slight modification to them so you don't have to use adapter plates. I've got a picture around here somewhere that I would post but I can't right now. My monitor died a couple of days ago and right now I'm using an antique 12" 16 color monitor that won't let me view my pictures with AC?DC.

So what exactly did you do to hold the adapter on? It is threaded at the intake.. and then bolted at the carb?

Flipflop: I was reading about you 45cc conversion. Do you have any updates or photos now? Was the carb adapter held in place with set screws? Thanks Capt,n
