Unsolvable problem with Stag it seems

[singapore stag]

Hi, here is a challenge/or brain teaser.
I have been trying to solve this problem for many many weeks if not months. I have the Webers fitted. Have got a new German made metal fuel pump new distributor etc etc.
I have tried my best to time the stag and adjust the carbs...but, the engine will only idle with choke out or the idle speed put up. The ENGINE KEEPS REVVING FROM 850 RPM TO 1000-1300 RPM UP AND DOWN UP AND DOWN ALL THE TIME AAARRRGGGHH!!.
Also if you look at the picture of my engine (posted) with the stroms, the location of the leads on the dissy differ from the usual location of other pics of engines on this forum. I swapped them around so the number one lead is on the right hand side of the clip and number two on the left as per pic posted.
Please help me to get the engine running.
Today i took off the cam cover got engine to TDC by lining up the two marks with the valves closed (can someone post pic of what valves look like when closed, i am sure the first one points left (the tip) when sitting in car. Got the pulley mark to 12btdc and rotor just near number two plug on dissy but to no avail. What are your thoughts?
The one who solves this for me will be worshipped.
Sukh.
p.s please notice the position of leads on my engine and the other one which is numbered. Why the discrepancy? I cannot remember for sure but think it was working ok with the leads as in the pic of my engine.

The engine rev up and down on its own accord.
Pity me old mate Russ is not on the forum any more he would have solved this by a batt of his eyelid! Ha ha.

That’s all very good Sukh but the important thing is missing. Where is the rotor arm
pointing? My guess is you have the dissy one tooth out. The rotor should point at the onboard bolt of the coil clamp at tdc. If it isn’t then take the dissy securing bolts out and lift it up turn it until it is. Sounds easy but will take a bit of patience to get it right. Also don’t bother taking
rh cam cover off to find tdc (Lomé it up at tdc not 12 degrees advanced) line it all up at tdc with your finger over the no 2 plug hole, the pressure will build up on the compression stroke somyou k ownyou are at the correct position.

Hope that all all makes sense.

The rotor is pointing just before the number two point of the dissy which lead goes to number two plug. Dont understand the coil clamp bit. Anyone got a pic of the actual location of the rotor facing the right way and location of leads please....
Tnx for replying

[singapore stag]

Goldstar.... I think i know what you mean. I will have a look. Forgot the rotation is anticlockwise. Got the rotor pointing just before the clamp.
Will report back. If it works, how do you want to be worshiped?

the fact it runs ok says the timing is close.
the roving up and down indicates an air leak.
have you over tightened the carb to the manifold, webbers have a habit of the bottom mounting flange distorting and leaking air into the manifold, may be lift it off and check it across the diagonal with a steel straight edge

reving even. auto correct again...read it before pressing submit

Sounds like an air leak Sukh, I’ve recently fitted new gaskets to my Weber and also the gaskets on the insulation bloc between the carb and manifold.
maybe worth a look?

Revving up and down, or hunting as it used to be known, is usually the sign of an incorrect mixture. As said above it may be a weak mixture due to an air leak. Check that none of the vacuum pipes have come off the Weber.

Dont understand???

Am I missing something here? He has strombergs according to the pic not a weber?

The way I read it was that it was an old pic when the Stroms were still fitted but he has a Weber fitted now.

Thats correct Webers. Engine was running sweet as a nut with Stroms......and they in my opinion look good. I am so self destructive sometimes, sigh!
Stag still not sorted yet.
Need to put leads in the right place on dissy, which one is the outboard coil clamp nut. Is it the one closest to the the dissy or the otherside near the right bank.
Rgds.
p.s there is so many conflicting pics of dissys with leads clipped in differently.
To be honest I did pull the leads off to do some work and lost the plot where they go. Also the position of the rotor, is it just before or after the number 2 lead location in dissy.

[Goldstar]

The rotor should point at the bolt holding the coil that is closed to the centre of the engine Sukh.

No comment on that statement!

Sukh, do you want me to PM Russ and ask him? Goldstar should be able to help you 100% anyway.
