I think I have to open may b 1/8 to 1/4 turn out .wen using the 45s .and how to check float settings?
-
Klassic motion.
Thank you for pointing out the jets.i just took the jets out from the carb n it says 50 on them whereas the original jets that came wit 38s say 45.so iam guessing I should put back the 45s back on dat carb rite?
-
Still the 32/36 jets in the carb.so I took a look at plugs .but I still c sum carbon on them.so I closed the bores like 1/4 turn more in . This adjustment better fix that .lol
-
Kool .I got it to where both bores open about 3/4s of a turn out.speed screw bout turn in.and wen iam on the street driving it.i dont feel any missing at low rpms.faster throttle response. Hear no backfiring while deceleration or acceleration. is it sounds like I did sum thing rite with it?
-
Now r all this adjustments to the carb done with the air filter on or off of the carb?

I went and listen to your advice on opening both bore.n so I did .there bout 1/2 turn out on both bores.and its seems like I have to where its tiny bit more towards the leaner mixture den rhe rich side.but I think iam done tweaking on this carb for today.lol

R u still using stock fuel pump or electrical?
-
Btw.that engine looks clean.
-
Now I get what ur say .wit the help of fuel regulator I can control the amount of fuel entering the carb.is that what ur trying to explain to me?
-
I bought it from ebay .part# wk663-38 .said it will work wit l series. Toyotas etc.etc.
-
But I got it to where there is no backfire in the exhaust.
-
Car runs fine now seem like to me .but iam not a professional mechanic.and I dont have machines to do tuning.and every time I change sumthing like splug gap or fuel air screw I take from a spin before I check my plugs for analysis. Lol.
-
Backfire was due to too lean of mixture
-
No fuel regulator in line. But my 32/36 was rebuilt like 11/2 yrs ago.so dey might have changed.it.also as of rite now iam only using secondary bore which I have at 11/2 turn out n it had eliminated the backfire which the engine was expriencing.primary bore is closed all the way.ie the one close to valve cover.
-
Iam running the gaps at .044 wit match box.u think I should make the gap smaller since iam using bigger carb?

Looking dat way but noy 100% sure.i still have to do fine tuning
-
O n I also changed the secondary jet too
-
But I haven't checked my s plugs yet.it was really getting late at night
-
I change the jets from my old 32/36s n it seems to run fine.and the mixture screw is 21/2 turn out.
-
Ritecat rhe momennt its at 21/2 turn out
-
Iam not sure on the 38s but wat I did earlier was i swapped my .jets from my old 32/36.into the new 38s n it seems to run fine wit no misfire at low rpms
-
What up fellas.
Just got this 38/38 weber dges carb with electric choke installed in my l20b engine.but it runs too rich.and also at lower rpms it seems to misfire but pulls hard in higher rpm.i only have 1 idle mixture srew at not even 3/4 s of a full turn out.my spark plugs get carbon fouled .any ideas what might b going on ? Need help guys.thanx
-
And where can I get the mild cam for l series for reasonable price also.?
38/38 weber?

U think a fuel pressure regulator is needed for this setup or this datsun fuel pump is ok wit it.? Cus I was reading bout webers its says the fuel pressure needs to b 3.5 psi or less for this carburetors.
