Is it true that the more fuel you can get your quad to burn the more power it makes? A while back we had a 210 main in a DS. It did not skip at full throttle at all. Everything that I have read says to richen until you get that hard skip but it never happened. We thought that it was to rich and dropped down to a 185. Which in theory makes more power? Who has ran these rich jets?

Hurycne, Does it run crisp with the 205? I went up to 195 and I was having a hard time telling the difference between that and the 175 so I split the difference 185.[img]i/expressions/face-icon-small-happy.gif[/img]

Logically, the more gas you have to detonate, the bigger explosion, which produces more power. But if you dont have enough air to equal the ratio, it will in turn lose power.

The oxygen burning is what makes power, not the fuel. The fuel is what is know as a catylist. You only want enough fuel to ignite the oxygen that you can get into the cylinder. Any more than that, and your displacing oxygen with fuel and slowing down the burn. Idealy, you want a 13.2-13.7 to 1 air/fuel ratio. Any more than that and the "burn" in the cylinder won't be full strength, any less and you won't control the timing or heat of the "burn".
