I'm planning to run it on Gas Glow first and I may go to EI.

The plane I'm putting it on, a 88" Clipped Wing Cub, is tail heavy.
I have a ST-90 and 1 1/2 pounds hanging on the fire wall and a extra heavy brass spinner
so I could use the weight of the flywheel. So that is still an option for me too.

I have a Toro and am in need of a mounting plate. Any suggestions where I can get one?
Thanks

Don't forget that you need to connect the nipple on the carb insulator to the nipple on the aluminum carb pump cover with a peice of fuel line. This will provide your pulse to the carb pump from the crankcase. The plug threads for the 2bbl Toro is 10mm. If you find an adapter, let us know. I am running mine on electronic ignition with a rear pickup.

Status: offline 		Hi Dave thanks for the heads up on the pulse for the carb,but I did have that covered.

What kind of numbers should I expect from my Toro on EI?
And which EI are you using?

If I can find a steel cased spark plug I'll go a head and make my own.

I was wondering if there was enough metal to drill and tap for a standard plug.
That would be the easiest of all.

Status: offline 		Rather than make them I bought mine from CH Ignitions. Less than $10.00 each as I recall. As for the pulse line I connect mine with neoprene hose. Doesn't harden up like the Tygon does. The Toro's I have done so far were the 1 barrel ones and I propped them for about 7500 RPM. Personally I don't like to run my engines above that. Very hot and humid most of the year around here.

I am using a Chinese brand-X synro style EI. It works well and was affordable. I got 8,000 on a APC 16x8 prop.

Tim,
Thanks for suggesting CH for glow plug adapters. I didn't know that they had the 10mm size. I guess they can make anything.

Dave

Status: offline 		I spent the hot part of the day installing the Toro in my Clipped Wing Cub.

I have run it some on Gas/Glow but out of the blue I ordered a CH Ignition for it.
I'm still not sure why, I just did. Any way it will be here maybe as early as Monday.

It flew very nice with the ST-90 but I had to / wanted to make it a gasser.

I had the batteries as far forward as I could get them and still had 25 ounces on the firewall
plus the heaviest spinner I could find.
I almost ran it with a Mag. just for the extra weight.
I'm using 1-inch standoffs to make the cowl line up.
If I figured right I'll still need 12 ounces on the firewall.

I'm going from a 13 x 8 to a 16 x 8 so take off should be about 10 feet
and I'll be able to idle along at a snails pace.

Here in the Sacramento Valley we get a North Wind 15 to 20mph often and this
should be a perfect setup for playing on those windy days when no one else wants to fly.

The last picture is of the L-4 I used as a model when I made mine.
After I get the motor tuned all I'll have to do is paint the cowl and it's done.
This was an abandoned 1/4 scale kit I finnished.

Status: online 		just an update on what these motors will fly for any of you that are interested.

all of the planes listed have used stock flywheel and a 11 mm carb, unless noted otherwise.... (2 barrel type motor) we are also switching to the lawnmower muffler and homemade aluminum exhaust header made from an electric junction box (light/cheap/works great) there is a how to thread on this forum...


GP super stearman/pt-17 stock 2 barrel, modified stock muffler .... flies scalish

Goldberg giant tiger stock flew lethargic, polished ports, 11mm carb lawn/muff flies respectable, now has 9 inch wing clip flies well.

cmp/china model hellcat 9mm carb or so decent homemade muffler....killer combo! flies beautiful. forgiving at 10.5 pounds

homemade 65 inch yak profile flies nice but underpowered, needs bigger carb and muffler, may get new engine (larger)

giant stinger was stripped down to a stick, almost 15lb's with DEAD stock toro...flew like a b-17 with full fuel and bombs, whew!

GP ugly stick 60-90 KILLER setup ! cut back to the second partial bulkhead,make tail dragger,battery and servos in back, make new firewall, 11mm carb, lawn/muff will hover at 8.5 pounds, no extreme pullout power, but ports unchanged yet...plane will never thermal away, but lands respectfully with short draggy approach...

a 60-90 ucando3d would be good plane also..
the cmp 190 should be perfect ...
gp gee bee would work, but deadsticks would be ugly...

You want to have around 900-1000 square inches minimum, but we have been smaller with success ....

Status: offline 		I see some people were asking about ballancing the Toro. I never ballanced the crank on the Toro. It was allready good. Most engines are pretty close. Only a few need ballancing. I just used a Dubro prop ballancer to ballance the flywheel on the mag versions. Good little engines. I wish they were as available as they were a couple years ago.

Status: offline 		Tell me about the tuned pipe.

Did you port the cylinder so it could take advantage of the pipe?

If so what are the numbers and how well does it perform against other boats?
