Hey Guys,
My RB30(Carby dual fuel) was kinda running bit too 'cold" yesterday, if I'm correct about that.
I was driving for about couple of hours in the evening and the temperature gauge doesn't seem to be
going as high as it usually did.
It's a fairly cold evening last night, for around 4-5 degrees in Melbourne, but
I've never seen the temperature gauge dial going this low even in colder days, after driving for that long.
I was running the heater on and off, but I do that in winter anyway.
I did "fiddle" with AFR mixture screw on the carby to get the petrol to run previous days back, but it wasn't
running on petrol yesterday and won't be for a while. So, it was on LPG.
It didn't make much difference whether I was stationary on idling or doing 80km/h on the highway.
I didn't think carby AFR setting mattered that much for LPG anyway, or does it?
LPG mixer has it's on AFR setting which I've never touched.
So, I didn't think the engine's running bit cold due to running too rich, or is it possible with my "fiddling"
with carby AFR screw??!!
When I started and warmed up before I took off yesterday for the drive, the engine was purring initially,
but didn't sound like as much purring on the highway. Kinda sounded bit rough, while I was keeping any eye on the seemingly low
temperature reading on the temp gauge.
So, I'm guessing,
1)Running too cold/too rich possibly due to my carby "fiddling" with the mixture screw? or
2)Coolant thermostat is in early stages of dying?
I took the picture while idling after I got home yesterday.
It idles around 950-1000rpm on LPG atm. I don't seem to be able to get it down to 850ish, warm or cold on LPG
Any advice please guys?
Thanx
