    Not mislead 85RamGuy ~ "perfect timing" (pun intended) as I should get to the point of finding it today -- I got my battery back from OReillys, they charged it but said: "it FAILED the load test, might have a bad cell..." My computer died the FAN ERROR fatal startup failure & can't upload photo from my phone SO THANKS A BUNCH for this photo you sent... I broke down 'n bought the remote start switch a dang cheapo innova Made - in -

    Yeah, setting the timing on a G63B/4G64 is a little easier than the 4G52/4G54 as you can see everything. You have spark - this is the hardest hurdle to overcome on a no start engine. Checking the timing is a PITA if you can't see marks but seeming you haven't pulled the head off or replaced the chain, you at least know nothing has changed there.

    THX geezer man -- got the battery installed & connected the innova remote start switch to the starter seleniod terminals S small terminal & B large terminal lead to battery and the starter motor would spin but did not engage the flywheel -- taking a break now -- going down to work on the truck in a few minutes -- 1st thing I wanna try is cranking the engine using the ignition key -- if the engine don't crank I will be very disappointed -- my battery cranked the engine strongly before getting it charged -- I just wanted to make sure it was fully charged after sitting 3 months -- it cranked the engine very well yesterday
    End Rant

    Fuel hose orientation? Fuel cut solenoid on the carb not connected? No fuel - at all? Distributor 174 and 3/4 degrees out?

    geezer ~ once I get my laptop computer fixed I can post a photo story ~ photos from my phone are not accepted for posting here... The wife happened to get a not too great short video of the sucessful startup ~ phone can't upload it either ~ all the more reason to try fixing my old puter...

    Finding that pulley timing mark was the key to unlocking the mystery ~ it was strange because original problem was flooding then turned into an ignition timing problem ~ kinda like trying to discover a flu or covid vaccine but the darn virus keeps mutating ~ the truck was having mutating problems (too many hands touching stuff over 'n over )

    More later & Mucho Gracias to all you MR50 Whizards

    can you edit photos on your phone? If so reduce them to 800x600.

    Dead truck towed home for a 3 month bed rest before a Mikuni heart transplant ~ https://youtu.be/Z4d6O2W-dsY

    1st starup & running, too much fogging oil, sounds like WWII fighter plane startup ~
    https://youtu.be/zzV380LVKFM

    2nd startup it's still fighting fogging oil ~
    https://youtu.be/oOPcH3FYD54

    3rd startup WWII Merlin engine sound ~ https://youtu.be/GYcKdK7hmEo

    Notice the oil stain under the steering gear area in the 2nd startup vid

    Before I started "fixing" on my truck it started first time by just pressing the gas pedal once then cranking it. 2 seconds of cranking and it was running.

    Sitting parked & waiting for timing light, laser tach and vacuum/pressure gauge test kit to arrive from Summit Racing -- ordered @ eBay a new throttle cable from seller in Greece -- have appointment for the annual State Safety Inspection tomorrow (no smog checks in Hawaii) received the hose pinch clamp set from Harbor Freight -- have thought about reassembling the J/Y Mikuni carb to visually inspect it's adjustment screw settings because other than leaking float that caused the no start, it ran well and had good slow idle -- should also inspect & measure it's idle mixture screw hole since the tamper plug is gone (might drill out the plug in the 86 carb to chase the high idle speed problem) Also gotta rechech TPS readings at idle & WOT and adjust if needed...

    Hurry up and wait for now (one SR box arrived just now, vacuum gauge ?) -- maybe get motivated to epoxy my busted throttle cable -- working on the truck is like being a prisoner at night trying to dig an escape hole -- no vehicle work allowed in the buildings garage -- resident mgr & a few cranky security guards limit what can be done during the night

    ALOHA & THANKS FOR ASKING
