I have put the softesd mech springs in already is that a good id. Be careful doing that, you may find that at lidle the spring is not strong enough to hold the advance weight in This results in it moving out, advancing the timing/ that increases rpms, Since you are running on the idle circuit only,...

Make good use of the forum search function.. detailed how toos on changing weights.. fixing weight to establish a curve on paper, filling off/ reshaping weight tails to limit advance.. making stops for weights and VA s etc
and lot of other stuff.

At any given rpm and load combo there is approx +/- 1.5 deg tolerance for best performance.. racing even less. To do that you will need data logger and at least knock sensor 02 sensor, preferably IMAP sensor. I have spent many decades dialing engines, old school thru to modern data logger/ sensor te...

Like it
not only that
and colour/ designs match the subject, something many over look.

Did you use the mounting holes that are on these adapters for extra support? A must.. a scrape bit 4mmx 15mm bar, bent and couple holes drilled each end.. one end mounts on a convenient point on the mixer extension.. mounting point or section joining nut/ bolt, down to a convenient exhaust, or powe...

Fun thing to notice was, that it liked timing to be pulled back from 32° to 30°, from 3000 to 4000rpm This is where the cam starts to work.. higher rpms and the overlap/ duration and cylinder pressure tend to increase a few lbs at this point. The dyno has AFR and knock readings etc? Dyno guys tend ...

I have been messing with LPG, classic, vintage compressions, re designing old engines, compressions , custom cam designes to run on modern fuels since the early 70s. All I can say it I get damn good results.... for the last 30 odd yrs, and with technology and data loggers etc becoming affordable in ...

Dont believe everything about electric fans.. If going to replace a fixed fan.. yes.. If a clutch fan.. no.. forget the marketing propaganda to sell electric fans (like the 'flexi fan bs) .. . there is no load on a clutch fan when it is not needed.. this is one of those old wives tails.. like HEI wa...

Eventhough, after everything I've done to my car, I still can't produce any MPG's to be proud off, as I'm currently only netting around 12mpg. Im between 15 and 16 mpg Also musty go right back to basics.. The amount of mixture used per mile is directly related to the volume moved by the engine per ...

Changing timing AND AFRs makes a huge difference in economy and power. Simply changing one or the other may only be slight, depending how far the other is out. Any timing change.. be it at idle or in the rpm range will require a a change in mixture....unless the timing is over advanced... and visa v...

Forget trying to relate petrol tuning (any specs) specs to and other fuel... doesnt work. I mention dial in.. this is what you have to do...Dial in means establishing the best tuning specs (as one gets the tuning specs in the manual) idle rpms... that is best stable idle at good afr..."best " means ...

Billhilly I hope I'm not coming across as harsh but there is a lot on the internet and much of it is generic or wrong. I will also add.. most old school pre dizzy mechanics didnt/dont even understand timing and the background behind it.. Damn near ALL modern mechanics.. or 'technicians' who only kn...

Little to ad to storms I take a slightly different approach in setting up timing.. both end up achieving same results...method in older posts Few things you need to understand. 1/ Never dial in timing increasing advance...as advance increases the tone changes, sounds better..this is sort of like a o...

Thats what I run at.. or very close. There is far more than just getting the O2 right, you need to combine that with the timing curve. The timing curve will vary due to load on the engine.. ie final gear ratios, weight of the vehicle and if running EGR or nor Also Vacuum advance at idle (enables low...

Mine is a dual plane.... no issues right out to leaning out high 4K / low 5K rpms sb 355 chev... which is around where it should be.. if anything a little lower.
