Got my other l20 in, with a little of Bleaches help, everythings fine, actually great, except it's studdering and backfiring, only when i try to mash into the secondary of the ol weber. Changed plugs, gapped factory, checked timing with a light, dead on. sound like the carb? Using the primary it works fairly well, but step into it, the truck coughs and sneezes.

I have been considering trying a 38 38 jetted for the l20b. any ideas??????????????????????????

ok, I'll go outside, yank the weber, bring it in cleanit up, and check the jets? sounds fine - be right back. any other ideas, i'll try em all.

Hainz, your transistor distributor is at Bleachatronics blue house. btw.

would it run 180 off? The engine is solid, Bleach witnessed the timing chain as being dead on, maybe something fishy with the distributor? I rebuilt the carb, which eliminated that, hey Hainz, do you have that picture of the dist tang position again? I lined up the v and dot on the oil pump, but maybe it's possible the shaft turned when i inserted it?

Ryan you should be good at this by now.
The dist shaft should be inserted with the dot and cutout on the pump. Bleach should know this also if he was there.
Put motor on TDC comp stroke.When inserted it will look like its in the 11.28 position looking from intake side of block.
Insert dist on to mount let it lock down. Where rotor points will be #1 plug wire and then go 1 3 4 2 counter clock wise. EZ!!!! You did this already

Im sure your using your old EI dist correct? If using the another make sure the rotor is pointing in the right direction. Maybe another was rebuilt the rotor was installed 180off.
Im not at work that where my photos are.

Thanks for letting me know you got the truck running,
I didnt know you wanted Icon info first instead of distributor info

how to time your oil pump at TDC comp stroke
