Had a family lunch so we had a play with the plasma cutter and made some exhaust hanger mounts

I borrowed a charger and fired up the laptop which talked to the stinger which is nice. 

I raided a k20 a zebra for the cam sensors which I plan to use for the crank trigger. Scoped out the sensor on the daily so I know what's going on

so I made a note of the jets etc

Primary main fuel jet is 140

secondary main fuel jet is 210

primary air corrector jet 170

Secondary air corrector jet is 180

Didn't pull the emulsion tubes out as cbf

I'm assuming bigger number = More fuel / air?

I'll wack the points dizzy back in as I don't fully trust the aliexpress and second hand dizzy to do its thing properly. That way I'll only be working with one variable/unknown rather than two.

Ordered some jets off aliexpress, and a fuel pump for when I rage quit because I don't understand carbs and rip into the injection. 

Replaced the engine mounts today

Tacked up the tailpipe and am fairly happy with where it's sitting. It's interesting how a couple of bends after the muffler really quietens stuff down!

That sums my current feelings up. 

It was pouring fuel in again, it was my fault for not tightening the base screws enough. Put the carb back on and it's still running poorly (un surprising as I didn't really fix anything) 

I dropped my brake hoses off at sterling brake and clutch. I ended up needing some custom ones made up as for whatever reason my originals were 20mm longer than every other tonner/hz listing. 

I'll go grab some washers tomorrow as I lost my other ones

so thanks to @1963 AP5 for the weber info. I pulled and capped all of the vacuum lines off the carb and put the solenoid in the correct position and fired it up. Still popping/backfiring and misbehaving.

I managed to get it idling and chucked the timing light on it again. The timing was on the piss. I thought I may have had the pickup coil polarity wrong on the module. Swapped the wires over and it wouldnt idle well at all but reved out cleanly but timing was WAAY to advanced. So my idea of using the gm HEI module wasnt as good as I initially though due to its internal advance and it not liking the low idle speed. I've lost my points dizzy somewhere in the garage so can't use that to test. I could go buy  genuine Bosch module for not a lot of money but I can get a jaycar ignition kit and barry it up myself for less money. That way I can use my barry jaycar progressive shift kit and rev limit module I made a few years ago. Might even be able to be a cool kid and do pops and bangs

Tonight I learned how to fail at AN hose fittings, Took a million attempts but I finally got it sorted.

The 202 breathes heaps because old and tired and the old airfilter was FULL of oil. I figured I'd polish a turd and use some of my finest aliexpress fittings and catch can to try and remedy that

Fixed photos in other post 

Re timing after I swapped polarity for the pickup coil the GM HEI module it the timing was 10ADTC at idle and with any revs it would jump to 20+ BTDC. so that was never going to work nicely. Atleast it was a cheap lesson (I bought the modules as spares for the van)

Ooh yeah barry time

Ready to do the smoke test and hopefully not have 30+ degrees of timing change. Bonus with this kit is if I get the polarity wrong on the pickup. I can just Wang a jumper in and Invert it

Soldered stuff  on

Made a less ugly Lead

Quickly connected for testing/setup

Wired it up and set the dwell/made sure it worked 

 

Quickly cobbled together a throttle bracket (it's shit, flexes and doesn't put the cable in the right place)

Now I can nicely mount fuses and instead of the industry standard stuff that's in there
