Intake/Exhaust Manifold Torque Settings?

[MrTougéTka]

Alright I've installed the new gasket, holy jesus it pulls now! No clicking from the spark plugs or anything. 

Might need a new tune and time again tho, it still dies coming up to intersections in neutral. Also bogs a bit when you go to take off, after that it mangs like no tomorrow

[MrTougéTka]

Also feel like its dropt a cyl completely now ugh, doesn't sound like a proper raspy 4k up in the revs. Still pulls like mad tho, it rumbles like a subi. What the hells going on sigh..

Lean probably, idle circuit not up to it.  Do the tune, and see if idle speed/mixture helps.

Tappet gaps, plug gap, points gap, timing..  if you've done it all then its a distinct problem to chase.

bugger it .

can u just plug up the pcv pipe (in place of the pcv valve) temporarily and see if that fixes your engine dying issue.

also, ive had 2 bolts come completely loose on manifold, both at the rear, and didnt notice anything. wasnt until i was doing my weekly lurk around the enngine bay that i saw the threads and laughed. Then i tightened them up as hard as i could with my fingers bent around down past the carburettor on a std size ratchet handle. I clearlu remember when i rebuilt the thing,  torquing them up to spec but it still came loose. i have the one piece gasket so the one piece gasket as pictured must shrink after multiple heat cycles. that suggests to me they need to be retorqued after a few thousand kms.

I'll redo the timing, sounds a bit tappy/pingy under load. I changed the manifold gasket and it improved quite a bit,. But is still present.

Brought a new fuel pump, new plugs, coil and leads installed. alsio have the carb apart as we speak getting a good cleanse! Plus a fresh rebuild kit! 

I'll get back to you with the end result.

I've played with the mixture/idle screws constantly since this started. It goes the best once you reset the mixture screw to 1 1/2 turns back from the screw being fully seated/screwed in.

which carb have u got?

ig its the one with a vacuum diaphragm controlled secondary throat, and the external hot idle compensator with hoses running to it, then the stock mixture setting is actually 2.25 turns. 

if u have this one (its most popular) and u are getting a better idle leaning it in to 1.5 turns then id say u have a spark leakage problem.

I've got just the standard twin choke aisan single down draught mate, I'm a bit of a noob when it comes to all this. But I'm learning quickly.

Hey is there any tips on refitting a new mechanical fuel pump? 

I've got the spacer , but I feel it Doesn't want to line up/slot in right when I go to install it.

[MrTougéTka]

Hey rebuilder 86 have you got Facebook? Its just I only come onto the forums with my pc, thats why I'm not on here replying every second.

yeh mate look for thommo thompson in perth picture of me holding my baby boy.

as for fuel pump. i don't know i havent mucked with them. I'm all for electric pumps! 

as for carby, there arr 2 variants of the twin choke standard. one vacuum diaphragm operated secondary, and one suction gravity operated.

need to know which u have before suggesting a factory idle mixture setting.

I'm pretty sure its the gravity suction version. Because there wasn't an external vaccum diaphragm?

[rebuilder86]

ah ok great so it looks like this...

in that case its the same as mine and depending on ur engine its 2.5 turns for 4k or if u wanna be lame and run it like the californians with the 4k-C haha, its 1.5 turns. see screenshot below of the manual.

[altezzaclub]

The fuel pump arm has to ride above the cam lobe, so it goes into the hole aiming upwards and you roll the pump horizontal to get it over the studs.

I can't think of anything else that might stop it.
