RE:
I've tried searching for the mods to "hotrod" the homelite 30cc, but have come up a little short. What exactly are the "hotrod" mods? I want to run mine on gas/glow.

Hi,
Do a search here in the forum and you'll find lots of info. The things I do to hop them up are things I have learned from experience, and also from a lot of study on the web. The boat guys use the Homelites, and you can find a lot of info about them and modifications on the boating sites. There is just too much to do and explain for me to cover it here in the forum with a post. I cut the squish band out of the cylinder head, lower the cylinder, change all the port timings, stuff the crankcase, etc., etc. etc.... It's a lot of work and I normally never do them for sale because I could never charge for all the hours of work I get into them. But they do run great when all hopped up...

Are all homelite 30cc engines equipped with a double ringed pistons? Mine is, and the rings are very narrow. About as narrow as a glow engine's piston ring. I think mine's from 1997 or thereabouts.

RE:
The narrow rings are good. Less friction and less ring flutter at high rpms.
You would be hard pressed to find a better deal than the one for sale in the market place. Even if you count your time at a buck an hour you would come out ahead. Just the custom two needle Walbro carb, the ignition sensor, the Twister Manifold, and the prop hub cost close to 100 bucks..... The whole engine with all the mods is only 150 as advertised....

The boat guys chewed my tail for even asking about modifying a homelite. Waste of time they say. I disagree as he knowledge gained is worth the time to mess with it. Though I am taking on a build for another forum member that will put the homelite on the shelf for awhile anyway.

RE: RE:
Well, for me it is hardly an "experiment". I've been flying these engines for years with zero failures. Swinging an APC 16 x 8 at 9400 rpms is some really decent power as well. Both of the planes shown have Homelite 30's in them, and both would go vertical out of sight. I lost the Christen Eagle due to a dumb thumb mistake, but I've had the Giles for 4 years and it flies super with it's Homelite 30cc.

There is a possibility I may just put the engine on the shelf too. I'm not sure yet.

I am calling my engine conversion an experiment because I do not want to fly giant scale. If I get the engine performing well, I'll most likely put it on my big 18"x32" airboat. It runs real nice with an ST .90, I can only imagine what it would do with 30cc at 9,000+ rpm.

RE: RE:
I won't run a prop that big, i was going to do a high pitch pattern prop. Maybe a 13x12 or 14x14. I'd want to prop it for 11,500rpm peak.
Before the pilots get cranky with my rpm figure, the engine would never unload since it wouldn't be airborne. That and I don't care a whole lot about the engine; I did pull it from a dumpster after all.
I figure it would be pretty light running without a flywheel and ignition system.
On a side note; my wife isn't fond of the noise much, I usually break engines in away from the house or wait until she isn't home.

RE: RE:
I got a NOS Homelite 30 cyl and piston assembly awhile back. It has the small cooling fins an a small combustion chamber with good port timing. It does however have what appears to be a de-compressor port above the Ex. port.
What is a good and easy technique to plug that port.

RE: RE:
Tap it and put a small allen set screw/plug in it. (Use Loctite) That's the way I do all mine. I don't think I would trust just stuffing JB Weld in it because of the heat, fuel, pressure etc.
If I remember right, the hole is already the right size for the tap so you don't even have to drill it, but I can't remember the size. 8-32?
I don't believe it is a compression release however. None of us are sure, but I think it is kind of an Exhaust Gas Recirculation port for smog purposes.
