What is Reddit's opinion of Powerbuilt 10 Milimeter Honda Jam Nut Valve Tool - 648827?

From 3.5 billion Reddit comments

It can be pretty tricky to get it right the first time. For one the engine has to be ice-cold otherwise you'll get all kinds of wrong data on the feeler gauges.

The process itself is simple in the sense that you have known valve clearances that you need to dial in, but there's always the right and wrong way to do it. I suggest finding someone more experienced who has done this a few times to walk you through it on your first time. There is a tool that makes adjusting the valves super easy since you'd otherwise need a box wrench and a screwdriver.

I would recommend you to get yourself one of these as it makes the job less of a pain to get right.

Valve lash is really easy but you need the tools to do it. Get a Honda valve lash tool like this: https://www.amazon.com/Powerbuilt-10mm-Valve-Adjusting-Honda/dp/B073WH1DBZ/ref=mp_s_a_1_3?dchild=1&keywords=honda+valve+adjustment+tool&qid=1598152330&sr=8-3

You will also need a set of feeler gauges like this: https://www.amazon.com/OEMTOOLS-25025-Blade-Master-Feeler/dp/B000BYGIR4?th=1&psc=1

There should be a video on YouTube specific for your engine along with specs for the clearance.

Carb cleaner and starting fluid are the same thing. So if it is running a bit but only on starting fluid, timing is probably OK and I would check the fuel pressure regulator and specifically the vacuum line. Disconnect the line and crank the engine and see if there is fuel coming out of the vacuum line. The diaphragm may have died and it would push raw fuel into the intake making the car super rich.

Regardless you likely have a fuel issue. See if you can get a Haynes or Honda workshop manual for the car as these should tell you how to check for fuel pressure. You will probably need to get a guage to accurately see the pressure.
