hey,
just got my new bundy, petrol 22R, and it seems to have a fuel leak in the lines?

It loses power on hills and goes into a chuga-lug-lug in the worst cases. I found the fuel level in the carby to be low and have tweaked that, does it less and not as severely but it still gets a bit of a power loss sometimes, very randomly! Maybe once every 20-30kms.


Anyone else had this problem with the 22R? could it be that i have a shit house brand carby? Anyone know of some good ones that i can switch too? Weber maybe?

the carby on my 22R sucks ass too..

If you had a fuel leak in the lines you would smell it for sure.Have you checked the filter to see if its blocked.It might be more of a tune problem on the ignition side of things.
Before you start swapping carbs make sure thats the problem.I dont know much about your carb but most carbys are ok if they are set right.
Pay a carb rebuilder to run a test on the emmissions then you will know for sure.
Sometimes a can of crc carb cleaner works wonders for 20 bucks
Im paying a carb rebuilder $240 plus $40 to rebuild, fit and check my FJ aisin carb today and Ive already told him not to go ahead and do it unless he is %100 sure thats the problem.

the carby on the 22R suffers from leaks around the buttterflt spindles on higher km motors, if it has over 200,000km this could be part of the problem, although it usually manifests itself as high, rough idle and poor low rpm/light throttle performance. what rosco has said about trhe fuel filter is the first thing to check, for a few dollars stick a new filter in there and see how it goes. treat it to fresh leads, plugs, dist cap and rotor and see if that helps, if no then start throwing money at carby shops.

that carb can be rebuilt/exchanged for around $300 which isn't cheap but when fixed up they do run very nicely, very smooth with no flat spots. they are famous for getting the accelerator pump clogged causing a nasty flat spot on quick throttle openings and yukky pedal feel.

it's probably not a leak.

I bought a rebuild kit for the carby on my 22r for $80-90. Was simple to install and fixed up a few little problems that mine had. only takes about 15minutes to get the carby off. 4 bolts, a few hoses and the air ducting..

I have a feeling that it could be fuel pump related as when mine died in the arse it carried on a bit like u are saying yours does.

Hope u get it sorted.

yeh, i have given it new leads and plugs, coz i thought it might be spark problems, now i think it is more fuel but it doesnt smell at all, the air intake is dodgy and i just got a new air pipe to the carby for $150 from genuine toyota, i thought that might be it and am yet to try it, i knew it had a leak in the pipe so hopefully? Also, am going to get a new uniflow filter for it tomorrow, after that if that doenst work i will look at how the pump is going. Thanks keep u posted...

WELL, REPLACED THE AIR HOSE, NEW SPARKS, NEW LEADS, NEW AIR FILTER, RESEALED THE ROCKER COVER.... STILL BLOODY DOING IT.

I AM NOT TWEAKING THE FUEL LEVEL TO COUNTERACT THIS PROBLEM. I HAVE BEEN PUT ON TO A GUY IN BRISSIE FOR CARBIES AND WILL GO AND SEE HIM THIS WEEK.

ANYONE KNOW OF THE SOME CARBY MECHANICAL GENIUS'S IN BRISSIE??

BUNDERA. WHERE DO YOU GET THESE THINGS FROM??

low rpm/light throttle performance. what rosco has said about trhe fuel filter is the first thing to check

THE FUEL FILTER WILL BE THE NEXT THING I CHECK!! LOOKS PRETTY NEW THOUGH.

You can get theose kits through REPCO.. They are manufactured by Fuelmiser so anyone that can get their products should be able to get u something.

I am still thinking that it could be fuel pump.

Is any oil leaking from the bottom of the fuel pump through the two little breather holes?


Hope u get it sorted soon mate.

Cheers,
Nick

Bundyboy after rereading your post and Bunderas post I would lean to the fuel pump theory.I had a Ford once that did the same thing yours is doing.It was hard to trace because sometimes it ran perfect.The reason was that as the pump warmed up it would lose just enough pressure to cause things to wrong.Turn it off for a few minutes it would regain its pressure.The level of fuel in the tank seem to have an effect as well.
You can isolate a pump problem by connecting a suitable fuel container and syphoning it into the carb.You would need to fix it to the bonnet and and devise a leak proof seal around the top of the container.One of those 4 ltr red plastic fuel containers would do it .Loosen the small breather cap to allow air in as the fuel is used .

yeh, i thik i will spend a day cleaning out the entire fuel system, filter pump carby etc. and then we will see how it goes, i think you might be right it definitely is not an electrical fault so it is likely to be the pump i guess.
