RE: Alchohol vs gasoline

I believe it's the nitromethane that makes the power, not the alcohol. Also, it takes nearly twice as much alcohol to generate the power of an equal volume of gasoline. Probably why the gasser planes...

Homelite 45cc & Walbro HDB-6B

I'm converting a Homie 45cc using parts from Wacker Engines. The carb adapter kit supplied has a Walbro HDB-6B carb, which seems awfully big to me! It has, I'm told, a 15+ mm venturi. Nice looking...

RE: Surplus McCulloch's

I have a couple of the 32cc versions of this motor. Reasonably light, fairly powerful and the block design lends itself well to easy mounting options.

RE: Poulan 42cc dies out

I had a McCulloch that would do the same thing. Turned out to be an air leak in the fuel line. Look for air bubbles in the line when you open the throttle...

RE: California Ryobi's?

Unfortunately along with the grooved cylinder it also has a single ring! It's been modified with a CH exhaust, tweaked carb, etc. He also discovered that the pistons on both engines are quite a bit...

California Ryobi's?

My neighbor (who got me into this small engine addiction) has been running an old Ryobi 31cc for a long time in a *big* plane of his own design, but always ran it on glow. It consistently turns 8K -...

RE: 32cc Mac.

Unless you plan to use the stock muffler, you'll find that the Mac has a somewhat unique exhaust port configuration that requires a special muffler setup. AFAIK, Abell hobbies is the only source for...

RE: OK, So I screwed up!

Jim,
If you move up the merger/food chain you'll find that Weedeater is now owned by the Electrolux corporation, along with a whole slew of other acquisitions. I think Poulan is in that group as...

RE: Homemade prop hubs...

You can also use a 1 1/4" or 1 1/2" hole saw. I use it in a lathe, but a drill press will also work fine if you can center it cleanly. You have to be a bit careful to avoid hitting the magnet,...

RE: homelite flywheel
