i i just installed a 3k carb on my sj70 all went well started it up drove it about 300m and then tick tick tick tick tick started F#$K

i checked the timing its at -8 i pulled each plug one at a time but the tick still never went away, if i put the clutch in and out the ticks still there. i cant feel any hesitation and its idling ok

i removed the filter between carby and fuel pump and messed with the idle mix and still ticking, take rocker cover off and have a look at the tappers ?

Did the oil level go up? May be leaking fuel into the sump thinning out the oil.

i thought that could only happen with a fuel injected car ? this is an old g13ba carby.

No, opposite. The fuel pump on an efi car isn’t attached to the crank case. (Well they might be in some very late model direct injection cars but not a g motor.

Oil Level looks fine, I took carby off and made sure the butterfly or something had not snapped off and fell into the manifold that all looks fine I'm 100 percent nothing dropped in it I had it sealed up the whole time. I'm starting to think tappet issue, will keep looking.

noise seems to have pissed off at the moment, i do think the oil i got in her is a little thick 20w-60 and will be changing to 20w-50 soon but she was sitting for a month between a start so maybe something just needed a good run to get it going again.

Sticking valve or may take a while to pump oil thru the tappet as it,s been sitting for a month.

Use the correct weight oil which is 15w40
