In a 4t engine the air is drawn (sucked) through the carb. and into the cylinder when the piston is moving down on the intake stroke.
In a 2t engine the air is drawn (sucked) through the carb. and into the crankcase when the piston is moving up on the compression stroke, then forced into the cylinder (pushed) when the piston is moving down on the power stroke.

I agree with rockynv. These little engines take a beating with no oil in them. There could be unseen damage. It may turn over smooth now, but if the balls or races in the bearing has gotten scored they will not last long.

Solution, sissy bar and or willie bar, maybe even a kill cord  Seriously, glad you are ok and the scoot only got minor damage. Use this as a learning experience.  A video would have been awesome  . Roy |

Kick the tires and light the fires. Check lights, blinkers, brakes, and horn. Strap on crash pad and ride.

I'm not looking. I have some friends that are looking for a small ATV for their son and found that scooter dynasty Has them. So I was just doing some research for them.

I have a socket that I modified with a die grinder to cut slots in the side, so I can install the keepers. I use a small pair of thin needle nose pliers to insert the keepers. I also modified a big c clamp to hold the socket when compressing the springs. Getting the keepers out is the easy part. Getting them in is the hard part especially with double springs.

I've had a keeper fly out doing it that way once. Spent 3 hours moving stuff and using a high power magnet to find it. I always use a valve spring compressor now.

I did find that Delfi makes an in tank version, that uses the same pump that I have, but they don't sell them individual. They sell large quantities to manufactures.
The tank on this thing is almost the lowest point on it. The radiator lines run under it so I haven't been able to see the fuel outlet. Just getting to the tank is a couple hour process because almost all the plastic needs to come off. Then getting the tank out is almost imposable I tried once before and gave up. I think they put the tank in first then build the rest of the scooter around it.

Depends on weather or not the pump will create enough suction to pull the fuel out of the tank. Some pumps must be primed to work. If they don't have fuel in them they will burn out. I'm not sure if the outlet is in the bottom of this tank or if the fuel pump has to suck it out from the top.

Some people just post a lot of nonsense and never really help anybody. All they care about is the number of posts so their title goes up. This is the nature of forums though.

Did you hold the spark plug on the engine or the frame to test for spark? Did you use a gauge or the finger over the plug hole method to test for compression?
A stock carb is big enough to at least get it running. If you are getting fuel to the carb but not into the cylinder a couple of things could be the problem.
1) The carb passages and/or jets are plugged.
2) The engine it is not creating enough vacuum to suck the fuel up from the bowl. In this case it could be:
A) timing.
B) valves not seating. (improper adjustment, bent stem, ect)
C) rings (if not installed properly)
If you squirt about a teaspoon or so of fuel into a vacuum nipple on the intake manifold it should start if you have spark, compression, and timing is right.

I'm thinking about another ecotrons kit as I have experience with them. I am not sure how I would mount the fuel pump as the tank is lower than the carb.. and the tank is a real pita to get to. The 300 is actually a true 276cc It will hit 75 pretty easy on level ground. The fastest I have pushed it so far is 80mph by gps. the speedo was reading  and it started vibrating bad, so I didn't push it any more but it still had some left. This magnum is still stock except for the horn and head lights. I have installed 55w hids and a bad boy duel air horn. Roy |
