Indian Tadpole

I noticed you went with those substantial brake cable guides, nice.

You can do dual trenching with that engine. Two stroke is close to twice four stroke horsepower.

I have an Cox Pee Wee .020 nitro engine somewhere, its is less power, but rpm is like 20,000 screemer. I had a balsa and shrink paper Spitfire Airplane that I assembled and put it on. It was not even U-control, just a string and made wobbly circles on 1 string. The 0.020's are not being produced anymore, maybe it is a collector item?

Steve,
You're moving right along! The steering looks good and the engine looks just right for your Indian. The end is in sight and motorbike summer camp is coming up in August. Woohoo!

MT,
What is dual trenching? Rick did a nice job trimming down the engine. I forgot to take some pictures of the stock Jacobsen, but will.

Steve,
Are you planning to use the Shell Aero motor oil with this engine? I'm guessing you will, same as for the Villiars Midget and 2 speed Sachs. What is the mix ratio for that? I forgot. Did I tell you I located a second Jacobsen through Curtis Fox which should be here in a week or so. I'd like to try starting both of the Jacobsens to see if I need to order carb kits. No doubt Rick knows where we can find the kits. Can't wait to hear these engines running.

Measure Twice,

When I opened the box to look at the motor for the first time my thought was .049 on mega steroids.

Steve, I must agree they look a LOT like RC plane engines once stripped down to the basics.
I forgot to ask if your going to take this masterpiece to bike shows?

SB the carb kit your looking for is a SDC walbro carb kit, did you get curtisfox's 40's- 50's era jacobsen? The one I sold you should start right up. 1st close choke , then pull starter rope slowly till you get a small drip of fuel falling from the carb then open the choke a pull starter rope briskly it should start on the 1st pull. However I have used a drill and socket to start more troublesome engines but thats before Ive done the carb work. Your carb was set prior to shipping

Yeah, it's a bit dusty from the wood stove this spring, but pretty soon will see active duty.

Curtis had one like this which I purchased and another which is smaller yet and I believe is from the 1940's. I passed on that one although it looks interesting.

Even in stock form the 147cc is smallish. I think it has a nice 1950's look to it and doesn't say... "I'm a screamer, way over 50cc"... so it is kind of a sleeper in that way. I don't want cops looking too closely at it and there's nothing on the engine announcing 147CCs. If asked I can kind of mumble the hundred part and be very clear on the 47CCs

I need to make up a metal plate I can put in the vice and mount the engine to so I can start it up. I've been doing no bike work so far this summer... trying to get next winter's firewood cut, split and in the wood shed. I wanna play with me motorbikes!

M.T.
Yes, the cable guides are a bit of overkill. Smallest tubing I had.

The Cox model planes were every boys dream when I was young. Spent more than a few hours admiring the latest airplane to appear in the local hobby shop window. Never did get one and had to satisfy my model aircraft desires with plastic models and half built balsa wood and tissue paper models.

I would imagine your .029 motor is very collectable. When I see one of Cox air plane motors I marvel at the quality of the workmanship and what they sold for new.

Steve.
 
I'm not sure just what oil I'll use in the gas. Being as these are a more modern motor they will use the synthetic oils I would think. The old engines needed the heavier oil because they didn't cool as well as the modern ones I believe. They needed the oil to stick to the metal and not run off.

I have the mix ratio for the engines some where but off hand I remember it being 1 pint oil oil to a gallon of gasoline. That would have been the old Imperial Gallon which was 5 U.S. pints.

You told me that Curtis sold you another Jacobsen motor. When I see yours in it's original trim I realize just how much work Rick did to get mine to where it is.
So happy I had him do it right.

Steve.
 
Rick,
I'm more of the type of guy that ambles down the road at bike and car meets just slow enough to be safe but fast enough to give them a fleeting glimpse and they have to get up and look down the road to see if they really saw, what they thought they saw. Then you don't go back that way again and everyone is watching out for you and you never show up.

Yes, I'll probably be at a lot of the bike/ car/ motorcycle shows we have out here between B.C. and California. As well as some of the motorcycle shows back east in the summer. It will be fun to see what people say.

Steve.
 
Silver Bear, I saw on "That 70's Show" an episode where they get into trouble using the station wagon Vista Cruiser to get back at a grumpy neighbor. This kind of trenching where you don't need a trencher to install lawn sprinkler pipes, when the idea is a bit different.

When I realized the power of the engine on the trike's two rear drive wheels and it sitting on a nice lawn, you get the idea.

MT
 
With a nice new pair of trail ripper tires on the rear? I mean the kind where if you drop a dime into the tread you will never see it again.

Steve.
 
And speaking of tread, I have the tires on the tri car. I'll get some photos tomorrow when I have more done to the bike. Tomorrows plan is to get the fenders mounted and the motor mount's welded in. Other than getting the gas tank coated with Caswell tank liner that should be all the fun. There is some body work to do on the top of the tank but that should take about half a day or so he says boldly.

Pretty soon it will be paint and final assembly time.

Steve.
 
P.S.D.

Aww darn it, you got in on the ground floor of the Animated Beaver. I tried but it's sold out and you can't buy in for love nor money. Your a lucky man indeed.

To compensate you for losing out on the chance at the tri car, when I bring it down how would a chance to run the tires off it be. Hate to see a fella get so close and have it slip away. :) Really looking forward to meeting you all.

Steve.
 
Just a side note on the OLD jacobsen that curtisfox has it requires leaded fuel or a additive. They are very durable. Even more so then the newer ones.

Rick
Silverbear didn't want the small engine i sent him another just like he allready has.........Curt

Thanks for poasting that i didn't know about the leaded fuel need

Hi P.S.D.,
Silverbear and I are talking about when and where at the moment. We should have it mapped out shortly. A great weekend for sure.

Steve.
 
P.S.D. Have to be sure we don't book the same time period as a fishing trip to Basswood Lake in the boundary waters with a neighbor, so I'll need to check with him. I'm voting for late August or early September when it is a little cooler down south where you are. Way south of here anyway. Very much looking forward to the meet up.

Curtis,
Fast shipping, bud!. The engine arrived today in good shape and this one has no dust on it. Ha! I've robbed a pull handle from a Tecumseh to fix the pull start.

I've fixed the pull start on the second Jacobsen. It sure has nice compression. I'll pick up a new plug for it and will give it a go within a few days.
