Chuffing landy

Slippery · Dec 17, 2006

Ok I took me landy out last week for a little drive and all went well for a
couple of miles and then it started to sound like a steam engine.
It makes a chuffing noise when I put me foot down so I took off the air filter (K+N) and it is pushing air/petrol mix back through the air intake.
It runs but it's got no go in it and there is no bangs or rattels.

So what do you all think ? valve stuck open?
Is this sort of thing common and any advice on removing the cylinder head.

Regards

Ps
Its a 2a SWB 2.25 petrol (3 bearings type)

head gasket is a possibility, i would remove the head, have it reconned anyway, then you have covered everything

Ta
I think you could be right as i have lost compression in pots 1 and 2.
O well it will give me somthing to do over x-mass

and is it best to get the head reconed or is it best to DIY it?

Get head tested and skimmed if needed, grind in valves and replace valve stem oil seals .

Well got the head off today and there is a bit of the head gasket about 15mm wide missing between pots 1 and 2

My questions this time are :-
1. What do you do if you snap off the studs that hold the exhaust pipe on to the manifold?
drill + tap or replace manifold?

2. How much gap is acceptable when testing for head flatness.

3. The head gasket I took off was copper (look's new) and the replacement I have from pad's is standard gasket material, so which is best ?
Is the new one likly to be better with a none flat head?

Also the Muppet who last had the head off didn't put back all the bits ie. missing rocker seat collets and missing inlet manifold studs / bolts and no thermosta.
Could something he failed to do cause the head gasket failure?

1) drill a hole and use an "easy out" to remove the old stud

2)none, i think the tolerance is less than 1mm

3) its as long as it is deep, either or will do the job but neither on a warped head

and you call the other bloke a muppet???????
