Fuel linkages 4108

Hi guys have trouble with Keeping rpms up Now engine starts And when MOVE fuel control lever on binnacle Engine revs up. Then Idles but down to idles. Feel disconnected And Not Positive as I would like it .. 1979 Cal 39 4108 Perkins Diesel So once again .. Start eng.. Throttle on up position Engine increases rpms Then eng slowly drops Back to idle...eventhough Is in full position.. Thanks Edward Stancil Cal 39 Northern Light

Check the simple stuff first. Sounds like it could be fuel starvation, but fuel not totally blocked. Replace fuel filter(s), looking at old filters when removed checking for signs of excess contamination. If filters are gunked up and that fixes problem, consider cleaning fuel tank.

Having rebuilt over 200 Perkins 4.108's in the last five years, I suggest:1- Disconnect cable for throttle. Hold lever about 1/4 position while someone you trust starts the engine. When she starts return lever to idle for one minute. Then rev it to desired RPM's If all okay replace and/or adjust the cable to the binnacle. 2-If cable linkage is okay, start at the fuel tank examining fittings and hose. Replace all fuel water separators and filters, being careful to bleed properly. Run the engine to test. 3-How old is your fuel? When is the last time you had the fuel polished and the tank(s) cleaned? Have some firm pump the fuel out through a water separator/filter, clean the tanks and add cetane booster to old fuel. Try to keep you fuel tanks full to minimize the air space in the tank. Daytime heat expands the air and it escapes the tank, evening cool draws moisture laden air into the tank, it condenses and the water goes to the bottom of the tank. 4-Have your fuel injectors tested, cleaned and calibrated, Take you F.I. high pressure pump to a competent firm and have it tested and repaired as needed. We use Atmore Fuel Injection in Atmore, AL. Be sure to mark timing before removing the pump.

Fuel filter and raycore. Disassembled wiped Clean filled bled system Engine stated.. (Before Engine cranked But would keep going) Injection pump is hidden And cannot get a view.. Throttle is hookup Backwards so back Is power.. Forward is off. But Tom is this a fuel Starvation problem ? It feels like linkage Is slideing between lever (on binnacle) and injection Pump .. when throttled Up then rpms increase But slowly engine goes Back to ldle .. Moving throttle back to Idle On Thu, Jun 20, 2019, 8:50 PM Edward Stancil <e.… [at] gmail.com> wrote: > Hi guys have trouble with > Keeping rpms up > Now engine starts > And when MOVE fuel control lever on binnacle > Engine revs up.

If you keep your hand on the lever do the rpm’s stay level? On my Cal 2-46, I replaced the throttle cable. I opted not to do the screw thing that would keep tension on the cable so it would stay where the throttle lever was placed on the binnacle. I didn’t want the possible moisture/corrosion entry point. So, our throttle will only stay up to about 1250 rpm - if I push it higher, it slides back down. We use a headband from my wife to keep pressure on the lever so it stays where we want it. I believe you can also get a different lever system at the binnacle that will lock it where you want it.
