191707 6030-01 is the code
I had a look today at it, looked at my eurocarparts clear filter and its already got dirt floating in it so decided to blow down the pipe, there was some resistance then no resistance so put the pipe back to the carb and the filter filled right up which looked like a highly improved flow started it and again revs hunting up and down :-(
Next step I removed the carb and found -
1 - No gasket between the carb and head so just metal on metal..
2 - big hole in the exhaust silencer (but guessing this would be just a noise issue and why its so loud rather than causing a running problem..)
3 - Probably the main cause of the complete problem, the High speed needle valve on the bottom of the carb was fully in!!
Took it apart anyway while it was off and cleaned it out, some dirt but less than I thought
Put it back together, set needle to 1.5 turns and idle needle to 1 turn and started it and it now runs without the choke, increased the revs but then it started bogging down and firing black smoke out (guessing too rich) so turned high speed needle in 1/4 turn and now revs to full revs but some blueish looking smoke starts to appear at full revs
It says to set the idle RPM to 1750 rpm, how do you know when its at 1750rpm? Do you need a special tool for that?
Thanks again
Just waiting for the carb gasket to arrive as well..
