Kirby Lauson VK30C Carburetor

Looks like that carb might be the way to go.
Looks like it might need a screw in jet in the bottom of that one.

UNC is a coarse thread. UNF is a fine thread. Cant remember what the U and N mean, something like Unified National.

Generally the finer the thread the shallower the thread is. (so the closer the tapping drill size is to the bolt size)

The older TVS90s are found on Victas mostly.
The newer ones ive seen on most, masports, victas even the odd Rover.

Bob.

Thanks Bob for all your help and advice, if this carb from steve works then im home and hosed if not i will try your re-taping suggestion, ive written down all the details you supplied.
I may even do it just to see it i can.
Cheers

Hi Bob,
Just got back from Ozzie tonight so will check with my neighbour tomorrow to see if Steve's carby has arrived then i'll get stuck in to getting her started fingers crossed.
While i was in OZ in port douglas i went to a bloke called Vics mowers in Mossman and he had never heard of a Kirby Lauson even when i told him it was an ozzie made motor.

cheers
Pete

Hey Steve,
I sent you a couple of PM's not sure if you've got them. its below

Just wanted to ask if you know what make the carby is because i need to try and find a needle and seat, My bowl fits and i have a bowl bolt from another carb that fits with packing washers only problem is, is the bolt supposed to have a jet or no jet.
The numbers 200 and 73 are stamped on the carby but no letters that i can see.

Cheers
Pete
