Maybe you should check the spark plug gap? Been reading that a lot lately and seems like that plays a big role. I believe it should be gapped to .025. Someone correct me if I'm wrong.

Aside from those thjngs, you should clean the fuel strainer and add an in-line fuel filter. Maybe even add some clear fuel hose, nice to be able to see what's going on with your fuel incase things in the future come up. Also clean the airfilter element or just buy a new airfilter, only about $7 from the Honda dealer.

I did a number of things all at once ill explain it in a video because I don't know how else to explain since im such a noob

how do i clean the fuel strainer
where can i buy the clear hoses
where can i buy a in line fuel filter ???

You can get them from a lot of places. For example, you can get them from treatland. You're gonna need a 3/16" for the fuel line and if you want to replace the vacuum line you're gonna need a 1/8". Make sure you get an in-line fuel filter that fits the 3/16" fuel line.

New clear line can be had at your nearest small engine dealer or repair shop, take the two lines in and tell them you want to replace them with yellow tygon line.

When doing this kind of maintenance, it's MUCH easier to get it running with the air filter off. Just squirt some plain gas into the carb opening. If everything is in order, it will light off first kick. This verifies that a whole lot of stuff is correctly done (spark, timing, etc). Much easier than trying to prime it through the plug hole! Or trying to start it with an empty carb bowl.

I just open the float bowl drain screw and apply some vacuum on the vac line of the pet * until fuel comes out the drain line. Then I may choke the carb with my hand if it still won't fire up right away, as long as there is fuel in the bowl choking by hand it just like priming the carb through the intake. Usually I just choke it with my hand and most stuff fires right up :-)

I see people talk about choking the carb. Could you explain what that means and how its done? I know the larger carbs have an actual choke on it but still dont know what it does, or how to do it with a stock carb. Thanks pat.

Greetings:

Put the meaty part of your hand over the carb mouth and crank the engine. The increased negative pressure draws a bunch more fuel up through the jets and creates an extremely rich mixture to initiate combustion. Theoretically it could unclog the carb passages if the resin isn't too adherent. You might hear just a couple of pops, and the engine sure can't run like that, but if there's fuel in the bowl, it should pop once or twice, letting you know you have compression and spark.

I use my fingers instead of my palm a lot of the time and just spread my fingers as needed to keep the right amount of air resistance to get it start. And keep it from flooding too much. Wheelmans advice of using your palm has helped me get more crappy old motors running than I can count over the years. It really does work to clear passages in the carb quick. I've been doing that since I was eight years old.
