253 rebuild not starting.

[chance23]

Electric fuel pump, so that’s no issue and it’s working fine.
Head gaskets were the right ones.
Compression was dry; wet they came up to 100 and 60 on number one.
It fires on the starter spray, so I’m thinking it might need more fuel. I’ll try screwing out the Quaddie another turn.
It shouldn’t be. I used the same cam that was in there. Unless someone swapped the cam years ago before I bought it.

It may have worked for you. I tried it once and it was hopeless - never again will I try it this way.
So quick to whip pump off, sneak a little vaso in while spinning by hand to get that suction noise, then reassemble.

I can prime a pump.. in about 2 mins (remove sender, screw in plunger adaptor and squeeze lever)
and am guaranteed oil pressure .

So you’re actually talking about pressurising the oiling system with a hand pump then? That’s a little different to drizzling some oil down the sender hole.

Care to post a picture of your tools used to do this?

like this .. see pic below(there are several different designs)

note .. the only bit missing in the pic is the brass adaptor (that goes into the clear tube and has a screwed thread to match the sender hole)

the brass adaptor?

yes.... sort of
you are forcing in oil (to push the air out) ... 'force' priming the pump if you like

Have you got enough choke working to run rich enough when cold?
To get my old Torana running on a cold day back in the day sometimes I had to warm up the inlet manifold with a hair dryer then pour some fuel down the Carby and crank it then BOOM she would come to life Full throttle is probably going to work best.
Just don't set yourself on fire

The cam would be correct.....From what I've heard if you have the wrong one, it won't fire.

And those compression figures.....Rebuild the engine properly....They are numbers you'd expect from a high mileage motor, not a fresh one...(oh and no offense intended)

That cam timing picture is wrong!!!!! what book did that pic come from?

 

[jcvhsle]

From my experience 17 pins between timing marks. That picture is only 14.
