Proddy Mod won't run

[mohawk]

This bike used too go like hell , but over the last 2 meetings its lost power and died .
It will start and idle with the choke on but dies instantly when i gas it.
Ive stripped and cleaned the carby twice, checked clutch, tryed new spark plug and electrics, checked gas filter, tank breather and fule lines and throttle.
Its got me stuffed, i did notice alittle gas around the intake when it idled without the air filter on it tho?
Could it be the reed block mabey? I doubt it would be a float level problem because it used to go well and i havent alterd anything.
Its got a 14mm carb, i dont want to pull the motor apart if i dont have too.

bro, does it have a fuel cock? These are really unreliable.. pull the cock apart and check it for crap stuck in it.

Haha, what?

Oh dear Mohawk. Steves on to it. sounds like a fuel starving problem. And it sounds like you've had a good go at trying to find it.. reed problem normaly makes it hard to start so wouldn't spend too much time on them. Air leak is a biggy between carb and manifold- manifold and engine. Whats the flow from the tank like ?? block in the tank outlet? . rule the fuel out then on to the spark whats the plug look like?? is the gap the right size on the plug?? theres a few to keep ya busy

[mohawk]

yup, checked plug and flow from tank all the way down to the needle valve.
Will check for air leak tomorrow.
thanks guys.

Haha what ya trying to say there lol..
There used to be a bunch of 10-12 guys that raced aroung the Base car park after 9 at night most week nights but haven't heard much from them lately. The Waihi thing is new and hope to adopt the same to a Hamilton location in the future seen as the kart club will not let us on.

[mohawk]

Yup, theres alot of racers in Hamilton. Just gota find a venue i guesse. The missus is keen as hell to get something sorted out.

go kart track???
or do some street races lol

[mohawk]

Ok, Bike still being a wank.
Took of inline fule tap and checked flow all the way through to needle valve. the motor idles with choke on fine and picks up when i manualy turn choke off. With the choke off it trys to go when i twist throttle but pretty much dies strait away. It just wont rev at all.
I did notice fine fule spray blowing out of carb when it idles tho. Will a d2 needle valve fit, it may be that ?

[CookMySock]

Try raising the float level slightly.

Steve

[BigAl]

Swap the carb for a D2 one, at least to see if it runs.

Try raising the float level slightly.

Steve

Thought about that, but i dont think you can adjust the float level on 14mm carbs.?

Ive got a d2 carb ill try tomorow, but the only part that i can imagine would wear out on the 14 would be the needle valve. Every thing else would only ever block up.
The bike was running mint, i want to find the problem , i dont want to change anything.

[Gadgit]

Hay Mohawk Just had a reread of all you have tryed and have you had the carb right out?? I would pull the jet and clean the elmulsion tube out. one of the 3 holes in the brass tube that goes throuh the center of the throte may be blocked ( I would say the center one is)
