    Rebuilt 2F seems to be going down hill

    When I get a chance I'll see if my old solenoid can be cleaned (if there was some gunk behind the needle perhaps). I'm curious and if I can get it clean I'll have a spare. What's amazing to me after opening the carb is the size of the idle circuit......that you can idle that big straight six...

    Rebuilt 2F seems to be going down hill

    Progress! I put the carb back on this morning with the new(er) idle solenoid. After warming up I was able to open the choke and had it idling at 600rpm!!!! This was with the idle speed screw not engaged at all and the idle mix screw turned out 4 or 5 turns. I realize that is too low and as a...

    Rebuilt 2F seems to be going down hill

    I did see it. I opened the linked thread earlier to read, but got distracted playing with my carb. Anyhow.....I had confirmed the fast idle screw is not holding the throttle open.

    Rebuilt 2F seems to be going down hill

    Yep and confirmed the smooth taper. I’ve tried adjusting the idle mix screw .....fully closed, fully open, 2-1/2 turns open. It doesn’t make any difference. If I release choke or let up on pedal it dies. Let me say again thanks for everyone’s replies. I know this issue has come up many...

    Rebuilt 2F seems to be going down hill

    I’ve seen that diagram before, but it never made any sense to me. After watching Pinheads carb videos today and pulling the air horn off my carb tonight I can finally understand it a little. I have a theory that 1) if works will make me feel ecstatic and stupid at the same time or 2) I don’t...

    Rebuilt 2F seems to be going down hill

    I did and no cracks. I also installed the block off plate and gaskets because the heat riser flap was toast. Ok I pulled the air horn off the carb tonight. I’m about to do some research because I’m sure this has been covered, but...... What is the route for idle fuel up to the solenoid? And...

    Rebuilt 2F seems to be going down hill

    Which implies my issue IS with my idle circuit. Solace: forgot to respond that I have tried adjusting idle mix but it will not idle without choke or some throttle. I did pull the valve cover to confirm oil (and I did confirm oil pressure during initial break in). My plan was to check...

    Rebuilt 2F seems to be going down hill

    Idle mix screw/pin looked good to me (I checked it a couple of days ago) even though I know that wouldn’t get past Mark. I had confirmed the solenoid was clicking, but yesterday I put a meter on the wiring harness connection. It was reading very low voltage. I have the 1 wire solenoid. The...

    Rebuilt 2F seems to be going down hill

    I forgot to answer a previous question: NGK platinum gapped between .050 and .055. Fuel does drip/spray from the primary nozzle. Fuel bowl stays pretty consistent at 1/2 full. I did verify, prior to break in, full voltage through my relay. After I discovered my idle issue it occurred to...

    Rebuilt 2F seems to be going down hill

    Thanks for replies everyone BTW. The side of the carb facing the valve cover (around the idle mix screw and vacuum advance hose) was wet with fuel. At one point I pulled the carb and noticed the insulator under the carb base was a little wet with fuel. I sprayed the carb base with carb...

    Rebuilt 2F seems to be going down hill

    By accident. I forget what I was doing, but I had my hand over the carb. I think I was trying to block some light glare to see down in the carb. Anyhow I guess I got a little too close and it sucked my hand down and killed the engine. I wasn't expecting that and it made a heart rate jump up...

    Rebuilt 2F seems to be going down hill

    I've started a couple of threads this week with random questions trying to diagnose issues, but I thought I'd try one last time before I call in the professionals (anybody know a good professional close to Little Rock AR)? My rebuilt engine is going down hill....... I had my 2F (11/78)...

    Do Aisin Carbs have vents - smoke machine revealed some sizable leaks

    Quick facts: '78, recently rebuilt 2F and Aisin Carb, desmogged (except no charcoal canister...yet). It won't idle below 1100 (and choke must be partially closed) and Idle solenoid is working, so I'm looking for a vacuum leak. I built a smoke machine, covered the top of the carb, and pumped...

    When should carb pull fuel from main jet?

    Nevermind Next step in figuring this circuit out was to determine where the vacuum that controls it comes from...the hollow bolt that holds the throttle plate to the carb body is the passthrough...the port is shown in the pic labeled 3

    When should carb pull fuel from main jet?

    I found this article (Aisan Carbs 101: Anatomy and Function) that states “ In cases of high manifold vacuum (high load), vacuum is pulled through a hollow screw in the center of the carb (between the base and the body) all the way to a hole in the air horn. This leads to the plunger pictured...

    When should carb pull fuel from main jet?

    I hated to start a new thread, but I have a different question. There is a Bolt in the base of the carb with a hole in it.....I’m assuming for vacuum? The hole for the bolt corresponds to the slight raised area on my carb insulator. Is this the right insulator? It looks like there were...

    When should carb pull fuel from main jet?

    Thanks for the replies. I’ll admit I’m being a bit lazy and was trying to determine if I could get closer to a diagnosis from the comfort of my AC. We’re having a heat wave with ridiculous humidity and it’s miserable trying to work outside. I’ll just have to suck it up and 1) clean out the...

    When should carb pull fuel from main jet?

    I have either a clogged idle circuit or a vacuum leak. When my 40 idles around 900rpm (it won’t idle below 800 without dying) I can see fuel coming from the main jet. I was curious if this would happen irregardless of either potential issue. In other words is it even possible to run 900ish...

    Wanted 78 FJ40 fuel door lock and key

    Yeah not sure what I was thinking. I just finished trying to get new locks all keyed alike and was temporarily confused. It was the ambulance door lock I ordered from Toyota and the gas door lock came with the set I purchased.

    Wanted 78 FJ40 fuel door lock and key

    I’m pretty sure they are still available new.
