Yes, best effort on my phone, I thought 28, 30 or 36. Top looks like 30 though, the 0 is quite clear so couldn't be anything else.
So, in summary, 30 vents, 60 idles, 122 mains, don't ask about the pump jet sizes and take off the cross head screw and photo the innards when the rain lets up.
If you crop it right down and save, your phone will display what's left at higher resolution. Doesn't work so well with downloaded images as the ones you take yourself and are still on the phone. This is a new discovery for me.
30x4=120 then up a size is the holy grail? If I try that it's frighteningly lean but my engine is weird and not in a good way.
I guess it is. If the main hasn't been a problem I'd leave it as it is though. 122 to 130 is a big step. When you jet the main, unneccessary richness wastes power. It won't hurt to try though you csn swap them back, nothing gets adjusted.
I can't say I noticed a huge improvement on 130's, I will try them again, but it's the popping that needs fixing first.
That damn popping! Nothing I've done effects it from 4-9 idle timing, 45 to 57 idles.. during that I've had afr between about 15 and off the scale lean during max deceleration.
Yes that's what it is. Stock doesn't do it. Was hoping stock might have been masking a jetting problem, my shouty exhaust on the previous engine didn't do it.
My problem is it didn't used to do it, and now it does, same exhaust, same everything, it seemed to start when I had it all apart to change the worn needle valves.
I keep wondering if the linkage is misaligned and is now causing one side to remain open longer than the other or visa versa.
Mine isn't bit yours could be. I'm still on course to block a tailpipe when I find something in a 2" can.
Linkages is are funny things, I can set a running balance at say 2000 revs with a meter, or set by eye and ear that the both are opening for the smallest twitch but when I get it right it's by revving it up and down like a boy racer while adjusting the balance with a screwdriver until it's smoothest.
The trigonometry on the CB Performance linkage gives me hives, if you slide the down link along the cross bar you're changing the angle of sine x (and the opposite side length) while keeping the hypotenuse the same. It seems to break all theorems that are supposed to be immutable, I guess the adjacent side must be getting longer too , otherwise it's not a right angle triangle? I need to think about this and then stare at it some more, then get a ruler out.
