Is anybody still viewing this thread? Is so, I have a inline 50cc that I need info on. I bought it here on RCU, and it didn't have instructions with it. I'm wondering what size prop to use. I've got plenty of experience with MOKI's, and really like them. But this is the first time I've owned a 50cc (the box says inline 350). I'm assuming that means 3.50 cubic inch.

It should be marked 3.60 on the box. I run a 24x10 on mine and it turns 7000 or so, but I still have it very rich since I just replaced the rings and bearings.
Be prepared to feed it LOTS of fuel and have plenty of papwer towel read. It is a nasty beast! I use a Cline regulator on mine, but I am sure it will run fine on muffler pressure if you can get the tank high enough. It has a unique sound due to it firing twice in each revolution.

Jeff

I believe that this engine came out before the 3.60. Just a guess, but the box says 3.50 and each cylinder has a 25 stamped on them which comes out to just over 3.0 cubic inch, so I don't know how they come up with 3.50.
Anyways, I'll probably try a 20X10 for break in. (This engine has obviously never been run.)
But thanks for the info. BTW, what mufflers did you use? I know Jtec and Bisson make mufflers for Moki, but I was wondering if you could manifold the cylinders together and have one canister.

That is odd since that 10.360 number is the part number for the 360 twin.
Mine says M180 on one side and 30 on the other which makes it a 360. I wonder if yours was rebuilt at some point with the older Moki 1.50 cylinders?
I am using the Bisson Mufflers, but would prefer a log style cannister with one outlet. DA uses that type of muffler on their 100cc inline twin.

Certainly not rebuilt. I would contact the factory and ask. This is important because they had crankshaft upgrades along the way. Early cranks were prone to breaking.

Wear a thick glove when you start it. I find it easiest to back flip against compression. Every once in awhile it will get into an odd cycle where each cylinder is firing in a reverse order from one another. It rocks back and forth only turning a half a turn....very strange looking and sounding

Yeah, but the DA is an gas (ignition), and I was wondering if the back pressure from each cylinder would interfere with the firing of the other cylinder.

I've had a couple of the 2.10's, and love them. Even though no one can understand why I still fly glow engines, but to each his own.

It shouldn't both are two strokes opearting on the same theory. It should have the same muffler pressure if you put the tap near the feont cylinder since MAYBE the gas from the front cylinder could create a slight vacuum on the pressure port if it was on the rear half??

I run methanol in some of my spark ignition engines. My little G26 turns 10,000 rpm on alcohol. I have a Sachs 4.2 on methanol, and I getting ready to run my G62 on methanol. I hate the smell of gas. They run MUCH cooler on alcohol too.

That's awesome! Do you use the same carburetor?

You can if you are handy. For the smaller engines, up 30-40cc you can use a Walbro WT499 which already has larger jets internally. Otherwise, you have to pop the welch plugs out and increase the jet size to twice the area, NOT twice the diameter. Takes a bit of trial and error, but its fun.
I will probably get an adaptor to run the 499 carb on my 360.
