posticon No Flow Of Fuel From Tank


Hey, I've just put a new engine into my GK76A after stupidly blowing my last one up with lack of oil.

I've more or less managed to get it all back together but when it comes to starting the bike there is no luck! I've established that there is no fuel flowing from the tank to the carbs.

Can anyone tell me what could be wrong? Any info would be greatful.

Is this the connection to the diaphram or the under side of the tank?

OK I have all the connections back together but it still won't start!
The spark plugs haven't got any petrol on them so thinking it's not getting through the carbs properly. At least on the upside now we have petrol moving down the fuel lines. I had a fiddle with the fuel tap and got the petrol moving. I think maybe just sitting around for so long has taken it's toll on the poor bike!!

Solved the fuel flow problem but couldn't get any go from the bike so after changing the carbs for my old ones only to discover they were leaking I put the same ones back on, pushed the ignition button and got a half spurt of life. 30mins of trying and stopping I got a great burst of life from the new engine!! emoticon

So for a bit of tinkering and I may yet just get out for a ride in the sunshine before the Scottish weather decides to kick in and start raining!! emoticon

you don't need to open the drain screws. The float bowls are vented to atmosphere so they self bleed. Just turn the tap to prime and they fill.

Re: No Flow Of Fuel From Tank


I always use fuel cleaner in my tank, a couple of times a year I put a can of wurth fuel cleaner in the tank and fill with fuel. Four years of ownership and no fuel related problems, even when the poor toys been little used it dosn`t give problems.
