Also try recarb in canberra i think ,good guys and no there carbs .Sorry don't have a number but they sell a lot of kits on ebay as well.

 

Mostly weber but do dellortos to.

I had trouble finding bits for mine. My dynotuner had a stock of parts though.

ok got it sorted and got them rebuilt

 

but it leaking fuel after i turn it off

 

what do you guys do about fuel return, thinking it might be getting to much pressure and pushing the fuel thought the carbies

No fuel return from my carbs, Pressure is controlled by the mechanical fuel pump..

Leaking from where? As in out the throats?

 

You DEFINITELY need to run a fuel pressure regulator on these things, stock K engine pumps will put out more than 4psi which is the absolute max for these things

 

Go get a holley red FPR and a cheap gauge.

 

These are pics of mine, I mounted the FPR off the manifold-carb bolts on an aluminium angle bracket. Gauge is downstream before the carbs, but I'm going to remount it onto the spare port on the FPR... One day.

ok sit up my return on the fuel pump and she not leaking fuel anymore

 

now its of to the shop for a tune

I am going to run a mitsuba pump on both my 2TG and K-B. You can get Malpassi filterkings cheap from Canada (about $USD70 inc post).

 

These act as a fuel filter and a pressure regulator for carbed engines.

Excuse the link. I have bought two of these from this seller.

 

Have had personal experience with over pressuring the needles on twin webers on an L20B. Did a great job of washing the bores. I don't recommend it

Yes I too will repeat - you need to run a fuel pressure regulator, or you'll find it.... tricky to tune.

ok so will get a fpr, this holley one is the 1psi-4psi model hey?

 

got a part number? will go pick one up tomorrow

Any speed shop will have them, just look for a holley red Fuel Pressure regulator.

 

I can't remember what the top end pressure is on it but it's well beyond 4PSI. You'll need a gauge too.

Or get one like this....

The 1-6 around the edge is the pressure in PSI..... still having a guage isn't a bad idea. :P
