Status: offline 		Could someone post some pics of the commonly converted Homelite 33cc engine, along with some prop/rpm numbers??  I scored a Homelite 33cc engine the other day, but I think it is different from the ones usually converted.

Thanks,
AV8TOR

mine looks like the 45cc homey and the poulan saws, but it has a weedeater style mount on the bottom crankcase half.  im going to go ahead and use it cause i'd rather not use beam mounts if i have an already made radial mount solution.

Status: offline 		Yeah, mine is different.  It has a differently shaped cylinder and the carb manifold is a spigot type mount.  I will have to make a manifold for it.  The engine seems a bit heavy too, at a tad over 3 lbs. without muffler, magneto or prop adapter, but with the carb.  It will lose a few ounces however, when I cut off the original oil pump and use shorter crankcase screws....

Here's a couple of pics.

Status: offline 		I did a 33cc Ranger saw from Depot last year. What Vintage is your saw? It is very different

Here were my initial numbers posted on another site of the first runs using a MAS classic 18x8:
She'll idle happliy along at 13000-1400RPM and I had 8300 RPM at WOT once, but can't get it back since I improved the mid range (tiny bit it did improve) but it will do a consistent 7700 rpm @ WOT.

I can't check the link from work but here's the old link to the walk around. About 1:30 intro and description of the bits.
http://media.putfile.com/Walk-around-of-converted-homelite-33
- In the vid I say "Hayes is ready to go for the glow" of course I meant gas, sorry.

Last time I checked they had another one but do I need another saw engine?

The decal on the engine says "Displacement 33cc Family 6HCPS.0338AA and the Homelite number is UT-10532, serial number ATJ2171262 and has a date of 08-05-06.

So the question is, what year(s) are the better 33cc engines?  Newer or older?  I was hoping mine was going to be like "J-3's" pictures.

Status: offline 		The 33cc Powerstroke engines from the Ranger and Bandit saws are the very best in this size range period!!!!!!  I have done a couple myself and they are true powerhouses!!  I run mine on the stock mag. ignition and can hand start them very, very easy....just have to know the right technique.  Mine will turn a Xoar 18x6 @8800+ and the Xoar has a pretty good load compared to most "cheaper" props.

Status: offline 		no i did not. i do know that it is less then my Quadra 35. i do have one here that is not done yet.  i can put all the part on a scall and see what it comes out as.   

The last time i did a RPM run i got 8200 with a 18X6 prop.  but that was with the old mufler.  i made one last year and did not do a RPM check.
So i did one to day with the mufler i made.  The RPM came out to be 8652.   not bad at all.

Status: offline 		Wow all stripped down it looks to be a pretty sharp engine.  With the performane numbers you guys are getting out of them it makes me mad im so damn broke or i would go get one of these.  Maybee i will get luck and find one in the recycle bin at the lawnmower shop. 

What size carb are you guys using to get the 8200 rpm on an 18-8 prop?

I ran the stock carb.  It had a 28 in the carb. not sure one what carb it is.

Status: offline 		"28" in the carb throat means a venturi size of 28/64".  64 divided by 28 equals .4375".  .4375" x 25.4 equals a venturi size of  11.11 mm.  It is an 11mm carb.  It would probably run a bit better with a 12.7mm carb, which would have a "32" casting number in the carb throat.  This would especially be true if you are running a smaller prop.  If you want to run as large a prop as possible for your application, it might do just as well with the 11mm carb, but only experimentation would tell....  I suspect the 12.7 carb would be better for most applications.

Status: offline 		Avi8tor i think it was you that told me tht the number in the venturi of a carb is the venturi size in 64ths.  Man I got to thank you for that.  it makes carb identification so easy.

I dont come across many chain saw engines at the engine shop bin.  i did score a 46 cc tht im hanging onto lol.  I do hope i can get lucky like you and score one of these.  i really like how they have the carb on the side.   the ryobis are such a pain with them on the rear.

Status: offline 		This one I have will make a good (and easy) conversion engine; but I have a bunch of engines.  If anyone wants it for $30.00 plus actual shipping cost, just PM me.  As I mentioned, it is like new inside, with no carbon and no evident wear.

Status: offline 		Help .. I Have a 33 cc conversion (from a chain saw) that I've done. The engine ran before I took it apart but now with it all together and mounted on the plane I can get it even to burb.. It has a blue spark.. but I'm not sure its getting fuel, but I don't have much experience with these engines. I've turned it over with a drill @ 2500 rpm both directions counter and clockwise and it wont even try to fire.

I'm wondering if I screwed up the compression somehow, turning it over by hand with a 18" prop on it doesn't take any effort. I feel kinda dumb, these things are suppose to be fool proof.

Any help or advice will be appreciated.

Thanks
Derek

Status: offline 		first, did you happen to rotate the carb 180*? if so, you might not have the pulse hole in the carb lined up anymore, I've had that problem before.

second, I see that's not a final setup since the plane isn't covered, but that silicone line isn't going to live more than a few minutes with gas in it.

there's a possibility that the fuel lines are backwards, I don't remember off the top of my head.

Status: offline 		I see 2 wires that go to maybe the coil...try to see if you get spark when you unhook them. Turn the engine over fast as you can with sparkplug on engine so you can see if it has spark. I 2nd changing the glow fuel line ot a gas line to carb. Best Regards Capt,n
