Plugs and timing for alky

[wheredahoesatracing]

Im going to alky and I need to know what plugs to run and what gap and where to put my timing im at +4 now. I have a stock stroke stock cylinder drag/play port by fast racing .040 over 185 compression with coolhead with 17cc domes 35mm mikunis converted to run alky with powerjets. Thanks

br9es .019 and different motors like different timing. i ran +10 degree's

b8es, b9es, br9evix, br8evix are all good plugs i liked .18 tho a lil better. you just need to keep the gap tight enough that the fule dosent blow out the spark at higher RPM's

 

are the domes alky specific or just shelf deto 17cc PD's? if they are gas domes you will need to be really carefull on the timing. once you get the jetting kinda worked out at about +4 then you can bumpo it up a lil at a time till it starts having issues and add fuel as you go if needed..

They are pro design and they are for gas so you are saying leave it at+4 till I get the jetting good then start to bump it up? I ran this motor on alky last year but they were stock size carbs and it ran really good and I didnt change timing.Thanks for all the help...

Add some powerjets and a big bowl/fuel pump if you don't already have them.
