ne could the fuiel filter be clogged

Experienced gardeners share their insights in answering this question :
Replace fuel filter and see. They are fairly reasonably priced and could be a quick fix. That could be the problem.
I had an engine and after resetting the timing I found after it ran rough I reset the dot one mark and it ran good after that. I would change the filter anyway and if it works it’s a lot less work.

rocker arm. Standard valve clearance: 0.15 ± 0.04 mm (0.006 ± 0.002 in) (IN) 0.20 ± 0.04 mm (0.008 ± 0.002 in) (EX) ⑥. If adjustment is necessary, proceed as follows: a. Hold the adjusting screw using the special tool, and loosen the lock nut.

Valve Clearance Tips

Recommended valve-to-piston clearance is generally 0.080-inch minimum on the intake side and 0.100-inch minimum for the exhaust valve. The exhaust needs a little more clearance because it expands more with heat.

A compression test reveals the condition of your engine`s valves, its valve seats, and piston rings and whether these parts are wearing evenly. Healthy engines should have compression over 100 psi per cylinder, with no more than 10 percent variation between the highest and lowest readings.
Running compression at idle should be 50-75 PSI (about half cranking compression). Snap throttle compression should be about 80% of cranking compression. Let`s analyze the results from the following sample test readings.

ANSWER : BEFORE you go thru all of the advice and look at most other Honda web
info…..go and buy a brand new spark plug and start with that! It
appears Honda used a NGK spark plug in the past that fails after some
time….giving the syptoms of problems with the carb, runs for 10-30 seconds, sticky valve, etc.

Do not try to clean and use the old spark plug!!

Check this out….it was the answer I was looking for after hours of
work, reading, and talking to Honda dealers —-

Hello i have a Honda GX160 and the engine will only run on choke if i close it the engine just splutters and thats it. it wont run at the norm i have replaced the carb the tank the air filter and the spark plug and know luck i have no more ideas as to what the problem really is thanks jord
ANSWER : Ii know you must have replaced the fuel filter. Did you replace the fuel line? It is obvious it is not betting enough fuel or it is out of time. Have you tried adjusting the jets on the carb? Have you checked the timing? There is a crankshaft key-way that may be bent just enough to get the engine out of time. And finally have you checked the fuel pump which I would suspect is your problem. The diaphragm may be busted.

My tractor stalls like it is starved for gas although the gas tank is full. I,ve changed the fuel filter and the gas cap. I’ve cleaned out the gas tank, gas lines, and the carburetor bowl. The problem seems more acute when the gas tank is full or near full. At this time to alleviate the problem, I blow through the gas cap and the fuel filter fills with gas and it runs good again. But as soon as the fuel filter has no more gas, of course, it stalls until I blow on the gas cap. As the tank gets down to about 1/3 full, the engine runs OK. What else could cause this condition?
ANSWER : I had a similar problem with a sears tractor. close to the carbarator is a rectangle box with a rubber hose going to the engine block – remove the hose and spray carb cleaner in the hose wait a few mins and try again – its a vacuum for the carb

Have a craftsman 16″ chain saw 358.360260. Could not initially get it started after it had sat for a couple years with fuel stabilizer in it. When I went to use it the fuel had all evaporated and the fuel pick line was rotted. I replaced that with some difficulty but finally got it on. Saw still wouldn’t start. Replaced the fuel filter. Still wouldn’t start. Pulled the carb apart and cleaned and recleaned everything. Diaphragms were good and I didn’t adjust any of the mixture screws because as I said it ran fine before storage. Non of the carb passages were clogged. Fresh gas 40:1, good spark plug and good spark. Airfilter is good. Engine has maybe about 4 hours of total run time on it. It’s a ZAMA (?) carb. It will run for about 30 seconds when I manually prime it by pouring a small amount of fuel directly though the carb. When I was disassembling the carb the vent hose that goes back into the fuel tank seemed to have a small out of ?substance? in it which I cleaned out. It was right at the end the of the hose that goes back into the fuel tank and not up by the carb. It didn’t appear to be like your typical gummy deposits/varnish though. I hope it wasn?t some type of spongy check valve stuff that is supposed to be in there. That might explain some of my problems. Anyway, I also can not seem to get the primer bulb to fill. When I open the fuel tank, look in side and depress the primer bulb, air bubbles come out of the fuel filter. But when I let the bulb reexpand there’s no fuel that gets sucked up the hose. I can however seem to fill the primer bulb when the fuel tank is full and the chainsaw is laying on it?s pull cord side and the bulb is depressed a bunch of times. The saw will also start and run again for about 15 seconds then die. It’s definitely not getting/fuel and probably running out . Thanks.
