Hey guys
Im sure this has been discussed before but I never found a straight answer

I have a 17084226 carb. Dont know who and when it was redone but it has a 73 with 50M rods with DA secondary

Its a bit lean on my 350 on primary circuit
9.5:1
Comp xe262 218 226 at 50
Edelbrock heads and performer intake

I Feels like a 73 with 50M thick rods 0.036 is a bit lean on the powe side
Can someone tell me if Im better off with 74 and 41k 0.026

Or how is this combo good enough

This is in a chevelle
And I read that M rods came on trucks
Not sure why

Other suggestion are great as well

Thanks

How is it cruising at light throttle? You could step up to a 74-75 jet & a 52 M rod.

omarghazzy:
Why M rod not K rod
Trying to wrap my head around this

Cliff Ruggles:
Where is it lean at?

Idle, off idle, light throttle, heavy throttle, etc?

What makes you think it's lean, hesitation, stumble, bog, surging, etc?.....Cliff

omarghazzy:
Hey cliff
It bogs if m doing light throttle then I push it half way to go up a hill or sth
Mainly on cold days if not fully warm up
It also feels a better when fully warm or its a hot day
Choke working file 5 min then fully open
Plugs are a bit too white
Thx guys

Is 73 jet enough for a fat 50m
