Hi,
Been struggling to get my Honda GX25-based tiller back to working. At this point, I'm suspecting one of two things:
(1) The carburetor doesn't visibly dispense gas. Is that how the GX25 carb works? I'd have thought that when I primed the carb, that the bulb would fill (which it does), and that gas would eventually drip out of the needle and into the main carb chamber, waiting to be sucked into the engine. Is that how this type of carb works?
I'm on my third carb, but the 2nd and 3rd are knockoffs from amazon. The second had a really flimsy plastic sheet in place of the spring that came with the OEM carb. I haven't torn down the third carb yet. All that to say that https://www.lawnmowerforum.com/showthread.php/57125-Incorrect-parts-for-GX-25 resonates with me.
(2) I've certainly had the tiller stall out on me a couple times recently (before it stopped starting) due to being unable to turn the tines (hit a rock, too much bermuda grass roots caught up in the tines, etc). After reading this forum a bit last night, I'm now concerned that my timing belt is off by a notch or two. Does that sound right?
As background, I've taken apart a lot of the engine -- pretty much everything that didn't involve taking out the piston or messing with the timing belt. Both before and after the teardown, I was and am getting about 90 PSI of compression (no idea at what RPM), as measured by one of those cheaper compression kits. I used some liquid gasket to seal the engine. I get a pretty decent spark from the plug and have now tried at least a couple different spark plugs.
Thanks!
