Help! I started up my 164 super today after its been sitting dormant for a good 6 months hoping to get her mot'd and back on the road.
It started fine but when giving it any more than part throttle it seemed like it was misfiring and is very reluctant to rev above 2.5k with occasional backfiring.
Its also running hot and producing foul smelling sulpher exhaust fumes and I can't work out what the problem is.
I took the air flow meter out and cleaned it but it made no difference
Any one else experienced anything like this?
