The last picture is your heater on / off valve..
I bet your heater stays at one temp all the time, its not got the cable attached.
Just a few things that aren't clear on the pics...left side of the carb, theres a big pipe, its a crank case breather pipe..were does it go...is it blocked off ?? If it goes nowhere it needs plugging.
also theres a wire going under the coil, seems to say resistive on it, wheres it going to ??
Have you a ballasted or non ballasted coil ?? can't see a ballast wire going to it ?
il ask then il go check,
first is the pipe u are talking about the brassy pipe coming from the carb? its never been pluged in??
second is the wire you are talking about the white wire?
third how do i tell difference between ballasted and non ballasted?
really sorry about all the questions but i want to do everything right!!
thanks
