my moneys on the ignition leads are on wrong!

they may be 180 degrees out

find number 1 cyl at TDC with the valves rocking shut remove distrib cap now the rotor arm will be pointing to the segment on the cap wich is number one on firing work anticlocwise with the leads firing order 1,3,4,2

it will start now re time the engind 6dg btdc

keep us informed

Hi,
What extent of rebuild?
Cam timing?
Valve clearances?
Head torqued down properly?
Dizzy drive in correctly?
Plug leads on wrong way round?
Cheers,
Gavin :)

The std timing figures (8 Degrees) is only for the std cam,mines on 16(I think) for a 276

Metro turbo weekend driver,Mini turbo in the making again!

just have to play with the timing mate, this is always a prop with the dizzy set up rather than mega jolt mate.

normally takes me a while to get it sorted

always looking for them bigger bunches of bannanas

Also make sure that the dizzzy drive shaft was put in correctly, This was the main problem with my first rebuild as i slotted it in in any old place! Let us know how you get on!

pretty sure the the dizzy is right but its not firing and i blew the carb out and even took the carb off and made sure it was clean cant seem to get fuel at the head i tryed and tryed just vapers set all the rockers running out of ideas when you turn it over its like coffing sound and blowing vapers out the top plueum where the pipe goes on to go to the turbo and at one point there was fuel but just on the two pistons both next to each other as you are looking a t the car on the left. depressing or what

yeah check the dixzzy drive it fooled me for a week

Are you sure the cam timing is right?

I had a problem with an air leak off the inlet manifold.. Plug the servo take off if your not using it etc, worth a check.

pretty sure the dizzy is in right copyed it out the haynes but i'll check today any other thoughts good please thanx

http://www.Zeemax.com

Yes there are more suggestions, here is one I have made, have you checked it?

isnt the haynes wrong tho (as in it tells you to put it in 180deg out).. or am i thinking of summat else?

trust me mate it always is a pain to sdtart a mini after a dizzy drive removal, last time it took me a good hour to get it fired up.

always looking for them bigger bunches of bannanas

Two stupid mistakes I have made in the past:

The dizzy rotates anti-clockwise, I put my leads on clockwise, I must have checked the firing sequence a dozen time before I realised what I've done.

Check the tappets, I once had a head skimmed & forgot to check the tappet clearances, turned out there were no clearances & the valves didn't seal.

The only think I can think of is the fuel pressure regulator.

would this stiop fuel at the plugs carb doesnt sound healthly i think that might be the pro any check you can do it makes a clicking when you move the throtle. I found it really hard going tring to make sense of that driveshaft made sure piston one was at the top and it only seem to go in one way and sightly turned anticlock wise when it engaged i think the to cut mark are vertal that sound right then i put the dizzy and moved it left to right when i was turning the car over no joy i think going to get a new carb just dont understand why theres no fuel at the plug any help before i have a big bill for new carb

is the pump working?

is there petrol in your tank?

have you plumbed the carb up right?

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

My Mini build diary

Cam timing incorrect. defo not this checked

Tappet clearances in correct, or bent valves / not sealing correctly. checked clearances and followed the haynes and i've head the head and valves all redone

Spark timing eg dizzy drive, dizzy position or plug leads incorrect. leads are correct. never touched the leads concerned about this dizzy drive but i position it and it seemed to only go one way as for the dizzy i turned it as the car was turning over got a bit of a back fire but didnt sound like it was firing.

I cant get my head round why theres no fuel my first turbo when i put it on a standard 1275 was throwing fuel out this nothing i have fuel at the pump and then nothing meant to go straight through the carb to the plugs but nothing this makes me think the carbs no good
