    Mikuni carburetor

    BACKGROUND HERE: http://www.mightyram50.net/vbulletin...Working-OR-Not

    This thread is about me & (you my helpers) trying to fix my 1986 Dodge Power Ram50 (32-35DID TF207 7Z08 Mikuni carburetor, California emissions)... It got broke trying to replace a leaking accelerator pump diaphram (cracked off a "L" shaped sliver chunk of the phenolic resin mixing body machined surface under the accelerator pump cover... It now leaks gas big time..! Truck sits...

    I discovered today that my carburetor is original & never rebuilt, photos coming soon... I also know that the 1985 carburetor from PicknPull is all same as mine (except it's from a RAM50 RWD not 4X4)... From now on, I'll refer to this carb from PicknPull as "1985" & my original as "1986"

    Today, got photos of the HOLE in the phenolic resin mixing body on 1986 and unlike the melted edge looking HOLE on 1985 there is at least a HOLE on both carburetors... 1986 looks as though there is a brass shaft in the hole & 1985 looks like a ball bearing deeper in the hole... At least I now know that 1985 is not trash coz of it having the HOLE in the mixing body... When I first looked at 1985, I thought "oh crap, a nipple or something is busted off"

    1985 has a slight sticking spot about half way through the throttle travel & 1986 throttle movement is smooth throughout full travel...

    PLAN ??? as of today --

    1) Spray carburetor cleaner 'n oil on 1985 and install it on the truck, cross fingers & hope to get toilet tissue as needed..?
    2) Investigate possibility of machining 1986 mixing body and installing a spacer under the accelerator pump cover..?
    3) Rebuilding 1986..?
    4) Locate & purchase a non trashed phenolic resin mixing body..? good luck
    5) Order an Ultrasonic Cleaner from Amazon (Jeff needs more CORONA$$BUCKS) and Aliexpress cancelled my order..!
    6) Leave 1985 alone 'n keep it as an example how to reassemble 1986..?

    At least not having wheels is helping me & wifey to remain isolated & quarantined at home, damned COVID-19

    Your thoughts guys & gals..?
