URGENT HELP NEEDED!
Turbo Mini Forums

Ok,just went to start my 1275 turbo up after putting it in the mini,when doing so petrol shot out of the anti run on valve,all spark plugs were wet,spun it over without the plugs and petrol shot out,more than what should be in there.so i need to sort this out as i dont want it to fill up again and bend con rods etc! lucky we stopped spinning it over,any help much appreciated!


thanks

sounds like the floats stuck to me. shit in the carb prob.
Take it off and strip the bottom off and have a good look around.
Not sure the old trick of tapping it with small hammer to get it to move/seat will be the best option.

Two things are infinite: the universe and human stupidity; and I'm not sure about the the universe.

we cleaned the carb ot before we put it in though,me dad rekons it could be needle valve?

could it be fuel pressure?

could be fuel pressure.. if you havn't set it..
Try firing it up with the pump off now the carbs full.

its spinning over and its gota spark,i hate it when things like this happens,never easy is it

well the metro engine came complete with the regulator attached,so we havent tampered with it and was guessing it would be set the same.....weve put 8mm feed and return. what you reckon?

if it still floods with the pump off then you know it's the carb and not the pressure.

yeah we tried disconnecting the pump (spi tank) and it wasnt having it, so your sayin its more likely the carb, needle valve or sticky float?

i hope you have piped the carb up correctley?
and you are not allowing fuel into the plenum!????i think this is what you have done to have so much fuel in the bores
and not to the carb, check that first.

if you are sure thats ok? then its the float valve
also check the pressure like doodmeister says

Also make sure the return pipe is not blocked or kinked along its length, as it can change the fuel pressure dramaticaly.

aha i was just looking at a pic on the net (im at work) and ive noticed ive connected the carb up wrong,looking at the carb from the front - ive blocked up the one thats coming out at an angle pointing upwards, and ive blocked the one where the carb meets the inlet manifold, is this why its doing it???

cheers

DOH!

been there!!

hehe dya reckon thats whats the problem?

Yep, you are just filling everything but the float blow.

Let us know how you get on.

good man you have sussed it
nearly been there

Cheers lads,i shall swap them over when i get home 2nite,get her started!! cant wait to hear that sweet sound of turbo and straight cut drops

il let you know what happens

guys, just so i can learn from this....... what do these pipes do exactly AND what are the effects if you block them up like i did???


thanks

That's the one i was thinking of

Ok guys,sorted that problem,it was that little clip thats on the carb float that keeps tension on the needle valve,changed it and it runs now,

now for the next problem, the choak aint connected so we set a high tick over and just nurse it by hand to keep it running,when you rev it up abit it backfires, and it sounds like its misfiring,played with timing but it still does it,so im wondering if al these pipes are fitted corrected...........the one im not too sure on is the one thats coming off the actuator, think it went to air pressure solinoid or something? i put a bolt in it but not too sure if its right

can somebody tell me what needs blocking off and what needs piping up where etc.

thanks guys
