Fj62 3f Rebuild

gday andy.
3f are quite a simple engine to rebuild nothing hard about them.
a cpl of things to remember is make sure you get the main bearings in right each main is different from the next.
get the crank crack tested there prone to breaking.
any good cam place should be able to grind something up for you.
cheers

Andy.
The mechanical workshop I used to go to when I lived in the northern suburbs tried everything to get the 2F and 3F engines to burn less fuel. After many years and many trials and tests and rebuilding lots of engines with different ideas on fuel consumption, he gave up trying.

Extractors....marginally better, just !!
Holley carby....bad idea.
5 speed box....well duh!!
Different cam grinds....a slight difference - hardly noticable.
Electric thermostatic fan....marginally better, just !!
Drive like my mum....a lot better.

He now just tells people to lay of the gas pedal and get on with other stuff.

AND YEP, ABSOLUTELY. GET THE CRANK CHECKED OUT.

I bought an FJ62 with a newly reconditioned engine and the crank sh*t itself at about 12,000 K's.

Andy, If you want to stick with the original carby (which I think is a good idea) in most major cities you will find a carby overhaul specialist. Freight to and from wouldn't be too much, only drama may be gettin' someone to tune the whole shebang properly once it's all done.

Be prepared for the cost though. I had the carby done on my FJ62 (on gas) and it came to over $800.00 !!!!!!!!!!!!!!!!!!!
