This channel is here to guide you through modifications to your small engine.
4200 Vortec (4.2 Atlas) Engine connector pinout
Pinout, connector part number, and wire color for the crank sensor, cam sensor, cam solenoid, injectors, ignition coils, knock sensors, coolant temp sensor, intake air sensor, and throttle body. Reference for vehicles with this type of engine or for people wanting to swap this engine into other vehicles.

First glances and walk around our new engine dyno.

Dyno is a Hewitt brand. Hardware and software is from DTEC. Video cut out at the end. I was trying to say It has a built in heavy duty sprag clutch that allows the flywheel to continue spinning in the case of a seized motor, saving what is left of the internals of the engine.

How to find ignition timing on small engines
มุมมอง 177K7 ปีที่แล้ว
This video is a step by step process on how to verify ignition timing on small single cylinder engines. The calculation at the end of the video that shows the distance of ignition degrees is correct for 2 strokes but will need to be doubled for 4-stroke engines. 4-stroke small engines fire a wasted spark on the exhaust stroke while 2 stroke fire every stroke.

Can i get your @mail ??
That’s the right way. That was the video I needed to refresh my memory. I was having a brain fart. lol. Thanks
Hello, I am working with the Honda GX390 engine. I need to determine the valve timing, how can I do this or do you have this information? This is the information I mean; 1) Intake valve opening angle:? 2) Intake valve closing angle? 3) Exhaust valve opening angle? 4) Exhaust valve closing angle?
How much is that .twisted builds ecu
Love it
So this ended up working well? I'm looking for a 4200 to build right now and I already have a speeduino. Did the gm 7x decoder work well? Did it have any sync loss? How does the vvt work? Thanks for any info.
What value is knowing the ignition timing if it can't be adjusted.
To relieve the compression wouldn't it be easier to just remove the sparkplug and ground it to engine. Opening the motor and removing the valvetrain seems like a whole lot of way unnecessary work.
What kinda throttle body was that?
❤
I'm curious, what are you after when performing this task? Advancing timing?If you wanted to ensure correct timing, you already got the engine out, pop the base gasket, and line up the timing marks. Put it back together and adjust your lifters. Seemed like a lot of effort for a unit that doesn't appear to have a timing chain. Great explanation though.
Nice vid, but it’s not necessary to do all that stroke finding, tdc is tdc no matter what stroke the engine is on.
How do I set the timeing on a small engine 49cc 2stroke please help me thank u
Could I get a copy of the wiring and connectors you show? I'm putting one of these into a 1941 Ford super deluxe
I still don’t get it: what exactly are we looking for with this timing stuff? I thought that the crank where the flywheel key attaches sets proper timing..? The key on the wheel is there to set up proper alignment. With that being said, why would all of this be necessary? Sorry I’m stupid on this
sometimes the key on the cranks or fly wheels are a bit off could be advanced or retarded but the timing is never perfect
Which wires are needed to start the engine on the stand? How much would you charge for a stand alone harness?
Great video
Cam it, turbo it, and chuck it in a C3 vette with a faceplated T56 and total suspension overhaul incl double wishbone/multilink IRS.
Aftermarket cams are not available for this motor. The OEM must be reground and then shimmed.
@@jedclampett6466 Same difference.
Man....I have a koler courage 17 on my zero turn. I bought it from a dead neighbor so I only knew it had 240 hours on an 07 model. Anyway, it didn't run so I changed all electrical components, all fuel lines, fuel pump, carb, fuses. Anything I could purchase....I changed it out. Anyway...it's hard to start but runs beautifully once I get it started, no stumbling, hesitation...nothing. I mowed literally 3 days ago and wanted to go do some mowing again today and it won't start. Could this be a timing issue?
This is a great video, really explained things well, only issue i have, is i cant get my timing light to work. Can u tell me how u made ur connections? Did u use a battery, did u have to ground battery to the engine? I checked my timing light by hooking it up to my truck..it works fine, but I can't get it to work on a single cylinder engine...plz help
In all my trucks, the 4200 is probably the most reliable engine I've ever had. They really are good engines.
proper bloke
Do you have any videos on Troybilt Weed Eater adjusting the valves and the torques specifications? Thanks for the video. I just subscribed!
Digital caliper, not digital dial calipers.
great explanator👍👍👍
My 45 year old 3.5 hp Tecumseh has the magnets on the inside the flywheel. What ya gonna do about that?
I really want to do a speeduino I was thinking for LS but one for the 4200 might not be a bad option now I just need money, a project car, some motivation
Does the spark plug fire when the trailing edge of the magnet passes the end of the 1st leg of the coil?
great video. I think a guy could lay the timing Marks out on tape. Just use 10 degree increments instead of marking out every single degree. It would still give you a close idea of where your at.
One thing you didn't mention is that there are 2 tdc one is compression and one is non compression some people don't know that
Yep, the second is the exhaust stroke, and as you know, the exhaust valve will be opening.
How do I make my 13 hp honda get fire to the spark plug
I have new coil an I have reset the air gap multiple times new spark plug still no fire thanks in advance
@@johntodd7318Try disconnecting the kill switch and low oil level switch and see if it gets spark.
Well done great video just don't encourage power tools to fasten up anything into cast alloy casings. I had to helli coil my Triumph head because some workshop tosser did this and stripped my threads. It maybe ok for undoing fasteners but thats it.
Well said mate..... so many using impact guns to torque up...fu!@$% idiots.
How did you know where make your mark on case
Excellent demonstration. The ending explanation of the degrees taught me something new. Thank you.
Needs a turbo and electronic waste gate! Exhaust manifold is steel and can be welded.
I have some turbo plans for it.
Ya I don't know about those electric wastegates anger Jamie split his block
Good work here
Are you running batch fire?
Batch fuel, wasted spark.
At 5:04 the pointer is at 0. At 5:08 it's mysteriously at about 30 ccw to 0. How did it get there? Just degree wheel moved? Or flywheel moved? Confusing? Is piston still against stop at that point.?
Nice
Nice. Very well done.
Can you do a video on changing the timing to 20 degrees?
why is this useful isn't the timing preset with the shaft key
I was wondering the same thing...?
I was wondering that too
It's not useful unless you are questioning the timing or want to set your own timing without the key.
How did you build this ?
With tools
Rrrr4
Just give me an idea, what to adjust flywheel or coil?
By chance have you finished the rest of the pinout's on the 4th sheet you wrote up?
Yes sir. Video will be up in a day or 2
Still waiting......
Would love a update!
Good timing, was learning about ECU controls on turbos earlier today. Nice to see someone walking through everything on an engine throttle body. Really brings some things together from visual standing. 👍
Kevin, you are ABSOLUTELY correct! I have used the exact same mathematical formulas as you were and find sooooo many mistakes in valve train maintenance as a whole. You can’t just go Willie Nillie in this area of the engine, this job, as any, needs to be done using proper technical procedures.
Sounds good
Appreciate it.
I did not understand : I wish of there is animation Video explains i to us
