Ticking noise under load...Hmmm

When did you last check/grease/change your CV joints... :?:

Cordialement,

:ok
I checked CV bolts were tight before my strip. The CVs themselves I haven’t checked perhaps a rebuild is in order?

I am going to re-do mine when I change the gearbox.
A quick test is to see if you can waggle the driveshafts from side to side. if it is too easy there is no more grease left... :wink:

Drove about 20km yesterday got worse and worse. Nursed it home and put it up on the lift. The fuel filter was completely clogged. I drained the tank and looks like there was another liquid not petrol in the tank also along with numerous particles. I had checked the filter before my trip so in 1000km it had completely filled with sediment

New filter in and it’s back driving like normal. Still a slight bit of pinking but the carbs need a bit of a clean out as I’m sure debris has passed through the filter. Also need to get the carbs properly synced and tuned up.

New fuel tank time. I just hope I haven’t done any damage to the mechanical fuel pump :(
