    I did a major boo boo while cleaning the carbs on my 83 interceptor..I followed the shop manual and ended up ripping the diaphragm in half.
    Wanted to do it by the book and my shop manual says that was the starter jet..I see now its a pressed diaphram fitting that was not suppose to be
    taken out...Can this be replaced and if so how and where to buy another 1? To explain it a lil bĂȘte you take the float bowl off and its the diaphragm
    with the pin hole in it next to the real jets..
    I am looking for solutions for this problem and would appreciate some advise and tips without any ribbing,lol..Go ahead,I desreve it tho for being a dummy..
    Thanks r24

    I think you mis understood me Kent..plus I may not be explaining it very well either..When you take float\bottom bowl apart from the carb,inside you have float,2 needle jets and 1 thingamajig I call a air diaphragm..it sticks out right beside the needle jets..

    I want to say that's for the starter jet/choke. There is only one diaphragm and that's on the slide. The only guy to go to is Billy C
    http://v4hondabbs.com/index.php?board=92.0 He has parts new/used and rebuilds V4 carbs for a business.

    That jet will pull out, then press/tap new one in gently.

    Bullshit, Grey !! "Only" is way off the mark ! i can't imagine you'd want to impugn the offerings of another honest craftsman to render a service useful for many riders without the resources or tools for the hours-long and often quite smelly process of cleaning carbs, are unsure about local dealers work quality or lacking time and willingness to do the job. Keeping more of Honda's old VF/Rs running as long as possible--if i can help carb-wise--is my one small contribution in the constant battle against vehicular entropy.

    i service VF/VFR carbs--as a business-- have very satisfied clients and charge way less than Mr. Bill and work much harder for a quick turnaround. i'm hangin' here on VFRW at least 3-4 days a week to offer info or advice or encouragement on subjects carburtetic IF i have the 411. Where is he with the same ?? Not interested ? Too busy shooting squirrels on his Texas cattle ranch ? Best thing ever come outa Texas is country music, that and Trilingua chilli spice, thanks Mr. Shelby.

    To ensure the enrichment circuit pickup brass tube is clear, a .010" steel wire is used to peck its way to a depth of about 35mm or use lung air and ears to check for flow.

    Squirrelman my apologies I forgot you are still doing carbs. Yes Squirreman knows what he is doing also, so Rob have two good ones to choose from.

    i've never had to remove a choke jet but always wondered if it was pressed in or cemented in or threaded into the carb body--got any pictures to show what it looks like under there?

    It's just a press in fit. You need a large set of pliers, leverage, to twist and pull out. Should be delicate in doing so. It must fit tight/snug going back in. Can also stake a spot at the base to hold them for good.

    No problemo, me amigo, Grey. Todo es mas fino.

    Long pick up tubes affect enrichment "choke" circuit at cold startup only, not after.

    Carb metal alloy is weak and brittle, and i'd never want to put the forces on to pull out the tube ! Even if one tube is clogged and non-functional, you still have 3 others to help start when temp is low using the "choke". I'd guess the tubes could be drilled a step larger to clear a clog, but if your bike is usually ridden above about 55F. ambient, not so much need for enrichment at startup........if carbs are in good nick and clean as The Queen's Corgy's blessed wee bums !

    Did i seem defensive ? YeaH, i'd admitt. I don't have a website or advertizing but like working on carbs and want as much work as possible, just to keep my restless hands busy and stimulate my mind since i don't have a cable TV (UNlike about 89% of guys here) for that and to supplement my pitiful SS monthly retirement dole............so i can afford to replace parts on my old VFRs.
