final build
11am. installed the needle and seat, and also swapped the baby monojets metering needle in. Realizing I had to remove an emulsification flood from the past days after installing, I let it climb to full warm at an idle (quite a task here in Maine right now). I must have some kind of luck… dialed right into the sweetest running little engine, after all these years of pouncing with japanese sized….”things”.
So to sum this up:
As it turns out, the number 80 jet that the little monojet was using was rather constrictive because of its design. dropping the slightly fatter needle with longer thinner taper, than the original taper needle through a number 79 where it can respond faster was a very lucky coincidence. hesitation is null..and its not even in the 60degree weather for really fine tuning a finale. The hesitation going away has a bit of everything above to gain. this will only get faster responses. the high static clutch is back in its happy place as well.
I basically resembled a chevette carburator on steroids, in a truck carburator body..keeping everything large but needles and seats, and adding an active fuel return, a resistor, and making the choke many times tougher than the fuse built in.
I also removed boot ring, found the boot fits right on direct fit, no modifications.

So to sum this up:
- little monojets plated metering needle (keeps the electric away) on the original larger power valve,
- through a holley #79 jet (fits hole better than rochester angle, nice modern bowl cut for jet venturi)
- my version of the float bowls needle and seat from little monojet, also plated.(old seat may even be radioactive..self electroplated)
- in the truck heavy duty monojet carburator body, with the bimetal relief area filled in…
- warmed up and lit by the choke I fixed my way.
- an extra resistor grounding on the back of the carb, acting as fuel heater, and light up the barrel per its own design (choke could not feed the barrel entirely- the all aluminum engine is very fast electrically)
- active fuel return
- EA82 valve cover bolt (interesting machining) to pretend to be a plenum center bolt at top of carb (static trick pulls at emulsifier per original design), sitting under hidden..
- a 1993 subaru loyale rubber like intake boot (full CAI to fender plenum- electrically stable)
- removed idle solenoid (12v live full speed ahead = electroplate the float bowl seat ) and replaced with a galvanized bolt(resembles choke pull) with a tease of different thread to lock it.
- custom idle mix screw (long taper- fatter end, brass nordic gold maker for the old hole.)
- custom flange gasket, (hand cut grooves after finding imprint- ensures equal vacuum, no swelling gasket to fill holes - air bleeders thanked me for it)
- choke pull to restricted vacuum (I found a brass reducer inside a subaru rubber vacuum hose) This is yet another thing to forget easily. the tiny pinhole at the end of choke pull is the size of reducer needed to go to carb..else it opens real hard and fast..can even stall a big engine. The four cyl let me know right away...and the choke idle refuses to be adjusted less than 2500-3000 rpm..any less? no cold start.
- mounted to automotive studs 3/8, brass washers, galvanized grade 8 nuts
