    Carb Jetting really low

    I have stock everything except an expansion chamber. The engine 2 strokes all the way down to size 64 jet. It has a good air/fuel ratio at around size 55 jet. This seems really low and even though she runs great I'm topping out at 30ish with a shift kit. How can I get more air to the engine so I...

    Bike fires but wont stay started

    Re-gapping the spark plug is a good idea. I'll ty that tomorrow when it's not pouring rain. I'll look at the gaskets tonight. Would they just suddenly go bad? This is a pretty new engine so they're not old.

    Bike fires but wont stay started

    And fuel flowing freely out of is what you want right? I don't have any way to measure psi but it's as hard to turn as usual.

    Bike fires but wont stay started

    Is the carb bowl drain test taking the screw out of the bowl and seeing if fuel flows? Ill check the tang but I just took it apart and this has been happening for awhile. I'm using normal lock nuts not the acorn nuts. Low fuel matches the symptoms I agree but I can't find anywhere that could be...

    Bike fires but wont stay started

    It is firing though so fuel is getting burned up. Basically i crnk on the pedals hard it sputters once or twice and then nothing. Most of the time there's no sputtering but enough that fuel would get burned I'd think. I took the carb apart and nothing was blocked or gooked up or anything. Fuel...

    Bike fires but wont stay started

    I've got a shift kit so i have to turn the pedals to turn the engine over but walking speed sounds about right. I'll double check the wiring and test the connections.

    Bike fires but wont stay started

    Head is fine torqued down properly. I took the carb apart and it was spotless. The plug wasn't wet but it was pretty dark. I assum this is from all the failed starts though. Every 50 tries or so I take the plug out and air the cylinder out to make sure there's not un-burned gas sitting in there...

    Bike fires but wont stay started

    Everything was running fine and then this problem started. The bike will fire a few times and sometimes and can even get it to rev but as soon as i let the throttle go it dies. I've tried everything at this point. There's spark, fuel, no leaks. When testing the spark plug against the head no...

    Bike wont start after fixing air leak

    Crassius it is in a channel of sorts, im not sure it's what you mean by channel though. The one i use is the same size as the OD of the intake pipe. And there's that lip in the carb that the intake would normally sit against and the oring just gets sandwiched in between the intake pipe and that...

    Bike wont start after fixing air leak

    It's not starting without the o-ring either now so there's that. I've got strong spark, compression, even fires a couple times on its own every now and then when i try to start it.

    Bike wont start after fixing air leak

    The problem is i can't get it started to test for leaks. I tested it for leaks before it stopped starting and it was only at the carb. Is there any way to test for leaks without it running?

    Bike wont start after fixing air leak

    As i said i checked thoroughly for air leaks in the rest of the engine everything is sealed up tight. I wasn't referring to fuel at all just air leaks.
