Another slight problem

[ricky0115]

Just testing my rebuild, kicked her over and it runs.... kind of. No throttle = bogs out & tiny bit of throttle and its revving so much I have to kill it! I've tried altering the jetting to where I can get it to run steady at 3-4000 rpm but that seems way to high, checked my throttle cable all seems fine and the carb slide is closing all the way. Out of ideas! Could be an air leak? Checked all the bolts and they seem fine, engine temp is good. Btw my horn works Also started fine first time without the choke.

Yeah it's an air leak.

@calum spotted it, on the top of the coolant temp sensor the yellow bit is coming away dripping coolant!

@ricky0115 Yeah but would take cause the RPM's to increase.
