what do u mean by checking the head over?
How can i tell if i am flooding the engine?

[Alburglar]

Sounds like You've tried everything. make sure that the fuel isn't more than a couple of weeks old because it only has a short shelf life. You've got a fat spark so It's not battery. you've got wet plugs so you've got fuel. But you have touched the dizzy so it is very likely to be timing. So i'd suggest starting again with the timing.

if it was running bad it could be knackered plugs!! if they are wrong rating they could burn out very fast!! if very lean mite be worth thinking about!!

remove the rocker box when setting the dizzy to make sure u have no1 cylinder firing when u think!! could have been 180degrees out to start with and flooded after that!!

if timing is 100% ok and you'r totally sure then leaving it for about half hour should cure the flooding or if u have an su carb try removing the damper pot whilst starting!! if it fires up ok put the damper back in very slowly!! only use a little choke if u do this too!!

EDIT: make sure there is oil in the damper pot!!

ive bought new plugs, leads, battery, points are set perfect, tapetts are set perfect, I have tried timing every way I can think of but have definately set it up correct now,

The problem now tho is that when i turn the key to fire it up it seems as if the car is struggling to turn over, it turns quick then slows right down then quick then slow etc etc, what could this be?

there is oil in the damper pot.

If there is anybody that wouldnt mind comming and taking a look it would be very much appreciated, I would obviously pay you for your troubles?

bad earth!!! possibly!!

[dklawson]

Describe how you set the static timing and tell us how you know you've got spark. Where did you determine you have a spark and what are you defining as a good spark?

[miniman207]

have taken engine out of car yet again!

noticed why it was not turning over properly, the flywheel was grinding the sides and the back of the casing, any ideas why it would of done this?
Also i need to get a new flywheel now as this one has seen better days! anybody know which 1 i need as i am getting confused whilst looking for 1!! it is a 1275 engine with inertia starter i think!

also once i took all the housing off so i could see if there was anything obvious the other side causing the flywheel to do this i noticed a plastic bearing with a metal ring inside (sorry best i can describe it) its located at the bottom of the block on the end of one of the shafts that stick through from the gearbox, anybody know what this is called? I will try and get photos up tomorow.

sorry for all the questions!!

Cheers

really need to see the pics first!! sounds like you're primary drop gear if its at the bottom of the block but the only plastic in that area should be the dust cover for the flywheel housing oil seal, if you have removed the flywheel housing and you're looking at the bottom of the gearboz then its the little bearing that supports the gearbox input shaft!!

[dklawson]

I can't tell from your description what the plastic bushing/bearing might be. As suggested by Fikus01, a picture would really help.

As for the flywheel, I do have an idea but you aren't going to like it. Yes, your flywheel is probably damaged (on its tapered bore). The crank tail will likely be equally damaged. You can dress the tail and flywheel bore to remove high spots then use lapping compound to reseat them to each other. However, it sounds like this may have already been done to your engine... multiple times. The problem is that for every 0.001" you take off the ID/OD of the crank tail and flywheel bore, the flywheel moves 0.007" toward the block. SO... fitting a brand new flywheel may correct the problem. On the other hand, there's just as likely a chance that the crank tail is so damaged that your new flywheel will still pull up too far on the crank tail. by the way, I've seen this before... on my engine. I was lucky and a new/better flywheel corrected my engine's problem.

hello this is the bearing thingy that was broke, and this is where it came from. the bottom cog thingy!! could you please let me know what it is called.

thanks

i think its a gearbox input bearing but its the small noe obviously the large being the other 1 in the casing!!

ouch! looks like you havent done much damage to it but to be on the safe side its worth making sure the nut hasnt come loose on the gearbox input gear, also chemc the bearing for play!!!! they have been known to and they can push / destroy gear!! i've seen 1 or 2 corcscrew into a flywheel housing!!

just a thought but you're timing issue could have been the timing being too advanced!! bit late to try it now!! could have been firing too soon and tryong to push the piston down before its got to tdc!!

safe bet to check/change oil pump while u can!!

[miniman207]

cheers for that fikus, there is quite a bit of play on the crankshaft where the flywheel attaches to, hence the movement and the flywheel munching up the casing and teeth!!! wasnt sure if i was a bearing missing as I only have a plastic thingy on the flywheel side then the oil seal but nothing on the inside so didnt know if i needed a plastic thingy on the inside maybe?? I put this engine 2gether so it is very very likely I have missed parts off!!

Cheeers

you should have a thrust washer on the centre main!! definately not something to be forgotten if u want smooth running!! if u didnt forget to put it in its possible that is got so worn it fell out!! i've seen worse happen!!

[miniman207]

would the bearing that is broke be the (BEARING, idler gear) ???

If so which one do I want?

BEARING, idler gear
Note: (1.065' O/D, 0.750' I/D)

or

BEARING, idler gear
Note: (1.375' O/D, 0.750' I/D)

or

BEARING, idler gear
Note: (1.375' O/D, 0.875' I/D

Y cant they make these cars more simple!!

[fikus01]

if your crank is moving forwards and back a lot its the mani bearing thrust washer!! inside the engine on the centre main bearing!! both sides should have a full 360 degree thrust washer!! gearbox off and turn the engine up side down and remove the centre main cap jobby
