My type 4 engine build...based on AP 1800

I have no notch....so I've just been lifting cap to check alignment

 

So, timing now set correctly, battery on charge, camcorder on tripod, fingers crossed. When do we start the drumroll? I love a happy ending! I usually cry!

 

No, because then the rotor arm will point at No.3. Just turn it backwards a bit from ATDC to BTDC...

Set the pulley so timing mark is at 7.5 BTDC (left of 0 degs).
Static time as before by turning distributor.
Now your rotor arm should be slightly before no.1

 

But will he be on no1... Or will he be on no3...

 

If he was on number 3 it would backfire through the carbs like a shot gun. Bit of a giveaway?

 

I'm making sure the now piston is at tdc and since the rotor arm is pointing to where it was when I first put it all together, I'm taking that as being at no1. When I had everything open this is the position where both valves on no1 were closed with piston at top

 

Are we there yet?

 

Do you line the centre of the arm or the leading edge with the lead?

 

Tweaked the static timing but still no joy. Started getting popping through the carbs now though. Not loud bangs but little pops

 

Do you have the old dissy with points you can time statically using a light. you mention you stressed over installing dissy drive. Did it go back one tooth out.

 

This is what I thought, so didn't worry too much during the build. I put the drive in with the 2 dots lined up and umm'd and ahh'd for ages over whether the slot was at 12 deg off centre line or not. I tried it a tooth either side and went for the one that looked right the most. I'll take some pics later, but basically I've now turned the engine till No1 is 7.5(ish) BTDC (to the left of the zero on the scale) and at that position the rotor arm is pointing towards the fan centre ish. Then I've undone the clamp and turned the dizzy body until the centre of the rotor arm lines up with the centre of lead No1 and clamped it back up. I've also removed the plugs, checked the gaps (all at 0.65mm) and cleaned them. They all had a little oil on them which I suppose is to be expected during first start up/running in etc. Still won't start though, but pops/coughs a little through the carbs now (or that's where it sounds like anyway). Hard to tell on your own, but I'll have another pair of hands tonight

 

Have you got enough fuel? Can lend you a can if you want

 

Hahaha great minds and all that....I'm sure I have, but just in case I actually filled up my jerry can this morning on the way into work, so I can stick another 20 odd quids worth in tonight for peace of mind

 

You filled up a fuel can this morning, you say.... planning on sticking in some more fuel tonight for peace of mind, you say.... now that is a coincidence

I would have been bowled over if you stuck a post up this morning about fault finding on a broken fuel gauge as well....

 

I sense you don't know how to static time. You can't time it with the rotor arm, you do know that? Static timing involes either a bulb or a meter, not just pointing the rotor arm. Pointing rotor arm is just so you know you're set at number one very roughly. Then you static time with a bulb.

 

I don't think you can static time an accuspark unit

 

^^ whs. @zed I have no points mate
