It's a TGB. It should have a Mikuni on it stock I believe. I'd say I'd send you one but the stock one I have seems to be junk after sitting in the elements for too long.
Any of the Jog style carbs you can find around should work fine with proper jetting.

Good Job Mike. I never thought there was a difference between a 2T and 4T carb. Always a Good feeling when things come to together.

Good Job Mike. I never thought there was a difference between a 2T and 4T carb. Always a Good feeling when things come to together. Oh yeah, there is a large difference between those two. 4 stroke carbs usually have a butterfly valve. Throttle only changes the amount of air that's getting in. Fuel, supplied to the cylinder is regulated automatically. It does it by having a needle attached to a diaphragm. When cylinder creates a vacuum to pull in the mixture (intake stroke), diaphragm moves up because of that same vacuum and allows fuel to get in. If you take a look at it while the engine is working you would see that it constantly jumps up and down real fast. That makes it great for fuel efficiency. Why? The fuel is only supplied when the cylinder needs it. Also, it works depending on the air pressure, so it makes it efficient over a bigger range of altitudes (I'm not sure about this one, correct me if I'm wrong) 2 strokes on the other hand have a valve with a needle attached to it. Throttle changes the amount of air AND fuel that gets into the cylinder manually. And the amount (ratio) is fixed. Depending on the altitude you might require different jets. Overall, 4 stroke carbs are more efficient but very complex 2 stroke carbs are more fun - faster, very easy to disassemble and work on, but fuel consumption and emissions are through the roof. Again, correct me if I'm wrong. |
