I've spent hundreds of hours grinding, blending and polishing aircraft frames and other parts. I spray or dip the carbide burrs into oil before starting the job and every few minutes there after. Works great. Take your time and use light pressure. Heavy pressure generates heat then the aluminum sticks to the burr. High Speed Steel burrs work very well on aluminum and are much cheaper than carbide. I'll have to give the candle trick a try as mentioned by Nathan.

[@michaelmorrotta3810]

The problem is because the stock valve springs are too weak for higher RPMs causing valve float and the rough running. You can use the Comp Cam valve spring set GP961-2 that are used on Briggs and Stratton engines for racing and that should help with the miss firing at high rpm

[@tkskagen]

The "Porting" could easily be done within a Blasting Cabinet for anyone that has one. When it comes to modifications and experimental Engine works, It's ALWAYS worth it!

[@heffedirte6243]

Those springs are way different. The diesel has more coils, thicker coils, and those springs would make a cam lobe completely circular and much smaller, really fast

[@jonathendoe1131]

Thanks for the lawn mower shifting problem video. I got my yard mowed today.

[@111000100101001]

Ah Yes, in the name of science and entertainment, definitely worth it! I can’t believe you haven’t built a ‘Redneck Computer’ controlled dyno yet ;)

[@SKOMPAS]

I have only just started the video and I don’t want to be one of those guys but here I go… A port and polish actually hurts low end torque but helps high rpm, when your not even hitting 4K rpm I can’t impinge it makes a measurable improvement, also as you can see by the hit and miss and high rpm the timing is off for this rpm (white smoke is diesel that didn’t ignite) I know nothing about the fuel pumps on these diesels but with the governor removed if you can advance the timing on the fuel pump the rpms and power will keep rising!

[@illernpiller]

You can change the timing with the shims that's at the pump from my understanding.

[@kylegoldston]

The extra sealant is probably the source of the debris clogging the oil pump screen.

[@lawrenwimberly7311]

red head "real Job" Jesse makes an appearance

[@michaelconroy8060]

I think that since it's a generator engine and thereby designed to operate at the fixed speed of 3600 in order to produce 60 hertz, then the optimum fuel injection pump timing is preset to 3600. With no other way to adjust fuel injection timing for engine speed, it will always run rough at any speed other than a constant 3600.

[@kleetus92]

I agree with the 3600 RPM part, but it should run smooth at speeds less than that so long as it isn't an odd harmonic... the 2 engines i have will run anywhere from idle to 3600 with no problems... there are a couple speeds in between they vibrate at, but not terribly so. If this engine can't make 3600 in stock trim, there's something already wrong with it. Being it's chinese, they use 50Hz power, which for a 2 pole generator would mean a top speed of 3000 RPM, in which case, 3400 ain't bad... but it won't work for us here.

[@UncannySense]

Forced induction on a diesel is where real gains can be made. If you're building it to just do drag runs you can skip intercoolers and integrated oiling systems for single pass runs.

[@JoshKilen]

with the single cylinder diesels, it hard to get a constant boost due to only one pulse per 2 revolutions, not good for a turbo.

[@UncannySense]

@@JoshKilen even just 3psi at 2000rpm will make a difference...I agree single cylinder pulse isn't ideal, But small chinsy turbos are cheap enough where any boost is better than no boost on a diesel.

[@JoshKilen]

@@UncannySense good luck trying to find a turbo small enough to supply that 3 psi at 2000rpms.

[@MrTheHillfolk]

You can add boost all day ,and basically get nothing. You've gotta add the fuel to get the power. Figure out how to crank up some fuel to it and add boost and watch it fly.

[@MrTheHillfolk]

You'd get more power for cheap by using water injection. Blue washer fluid to be exact. Set up an old washer bottle with a 12v pump on it ,run a line to the intake and restrict it with an old jet. Keep increasing the size until it chuffs a little and back it off. Set it up right and it'll feel like a mild nitrous hit. And another benefit is it removes carbon, it'll be almost spotless on teardown except for color like a seasoned cast iron pan.

[@starpuss]

She just needs injector pump mods / stronger springs on the pump return, may help.. but seems like you have other problems still becauseat 3400 RPM they normally dont do that. . , did you remove your shims or just go down to the smallest size you could find. ?? Seems like you actually have a timing issue also.. But.. During "redline" it sure seems like its floating the values itself still seeing you are just blasting un burnt fuel like crazy.

[@redneckcomputergeek]

Agreed. I think it floats the valves just as it passes 3900. I did try removing all the shims. No luck at that point to pass 3900. The pump return is the smallest spring in the top of the pump. Reality is fun idea but we hit the limits way sooner then I expected to.

[@rncboy2]

Chuck the valve stem ends in a drill an lap them that way. Beats killing your hands trying to use the suction cup lapping tool. Just a thought for next time buddy.

[@adventurewagen]

the carbide bits with bigger spaces between the cutters are made for aluminum, those are for steel thats why they plug up. harbor fright has both for steel and aluminum.

[@prodabpaul8736]

Very nice I would like to see what you could get with one of those RHB31 turbos on there

[@BelusTraveller]

Bro the popping and white smoke did you ever get through that to make it run smoothly,

[@jimciancio9005]

Your fuel injector pump return spring is the limiting factor and not the air flow, just FYI.

[@lawrenwimberly7311]

BTW... an extra 600 rpm means a LOT in the higher gears

[@redneck3848]

Nebber b are also called rasps

[@starpuss]

Lol , just thought I would ask.. What cetane leavels are you running in her?? It actually could be all your problems..

[@jimbo8v92]

Did you do anything to the flywheel for the sensor to pick up a rpm signal? Im putting the same engine in a tractor im restoring and ordered a tach that uses a similar sensor.

[@Gmcworrior1]

Might do this to a smaller gas engine. Nothing expensive

[@karolstruck9822]

Soak your Burr in hydrochloric acid also known as muriatic it will eat the aluminum and no the burr. 🤗 Better Living Through Chemistry keep up the good work

[@tkskagen]

If you have a "File Rasp" you may be able to get the melted aluminum "slag" off of your Carbide Bit.

[@travischambers9513]

you should make the old chevy power wheels into a gas or desiel power wheels

[@wyattdouthat4448]

If you want to do a hire rpm you also need a bigger fuel igniter

[@blackstorm86]

It's a diesel.

[@jimphipps2413]

Any game is probably worth it whether or not it's enough remains to be seen when you put it on something and run it

[@illernpiller]

Porting a diesel is kind of pointless as it doesn't have a carb, but smoothing it out and getting rid of ridges etc is good for better air flow.

[@MrTheHillfolk]

I bet someone ran it with the packing oil. Mine was like that ,it galled a lifter from not spinning during break in. I was able to save it but that stuff is nasty like crude oil, or almost like heated tar.

[@mbflower]

Whatever happened to this diesel engine? Did you install it in a mower?

that "oil filter" is a intake screen to the oil pump.

[@MrTheHillfolk]

Those pumps are wicked too, they can put out 150-180 close to 200psi when it's cold because there's no relief valve

[@MrTheHillfolk]

Haha if you try an oil pressure gauge put a 0-200psi one on it. Theres a vid of someone on here with a gauge on it.

[@JoshKilen]

@@MrTheHillfolk I did not know that, I always wondered what the max of those pumps where.

[@steveeisenhauer3003]

So an intake screen isn't an oil filter????? My manual calls it an oil filter. 🖕

[@JoshKilen]

@@steveeisenhauer3003 technically yes and no, its oil filter. The reason why I say that is the reason why its an oil filter it does filter the oil down to a point. And the reason why its not an oil filter is because it only screens the oil down to certain point and and doesn't filter and have the dirt holding capacity like a normal oil filter does. if that makes sense.
