Posted: Fri Apr 06, 2012 11:42 am
Hello everyone,
I'm new to this forum so hope someone can help.
I have a problem which has been discussed before, I have read the previous posts but I am still having problems, here goes...
PROBLEM
My Qualcast 43S only runs on full choke, as soon I adjust to half or no choke, the engine stops.
SYMPTOMS
It's running very rich, black soot all over plug.
Drinking petrol!
TRIED SO FAR
Adjusting the main jet to 1 3/4 turns out.
Cleaned carb.
New air filter.
Removed head and de-coked.
Help! it's such a simple engine and set-up I'm at a bit off a loss now!
Thanks in anticipation.
Nigel.
