@@autotech4103 Honda GX270 T1, with a Sinco 5kw Generator. Stripped it all down, apart from the engine crank casing. Old weathered parts, gaskets,a replaced, rust removed, paintwork rubbed down and resprayed. Now putting it back together
Hello, I am working with the Honda GX390 engine. I need to determine the valve timing, how can I do this or do you have this information? This is the information I mean; 1) Intake valve opening angle:? 2) Intake valve closing angle? 3) Exhaust valve opening angle? 4) Exhaust valve closing angle?
I imagine you are using this engine for a high performance application? There are forums for "Carting" such as 4cycle.com/karting/threads/honda-gx390-stock-timing-what-are-you-getting.87635/ The information is probably not release from Honda themselves as they don't want to be messing with warranty claims and such. Hope this helps........
During assembly you don’t have much of a choice other than redoing it. The manual doesn’t specify so I will assume the numbers they give is for a cold engine. A hot engine would need less clearance.
To shutoff the engine the ignition coil is grounded. I would try removing the wire from the coil from the plug and try touching it to ground with it running. If it works the problem could be how it’s wired or the kill switch.
Would the valves being out of adjustment cause it to pull gas into the crankcase,I'm having problems with gas getting into the crankcase and I've rebuilt the carb and still having the issue
If it’s a four stroke engine then I would assume it has a float stuck down or a hole in the float so it never closes. The only way for fuel to get into the crankcase is by washing down the cylinder and getting by the rings. If it’s a two stroke then that’s a different story
The recoil hub and plastic blower mounted to the flywheel are all located by lining up pins. It’s possible that yours has put together improperly. It’s a pretty easy fix. Just take off the red cover and flywheel nut and pay close attention to how the blower and hun are suppose to go.
Good video. Not exactly what i was taught for adjusting and locking nut some 35 years ago but same result 🙂
Good stuff!
Perfect thank you
Thank you very much sir
Wow, looks like I missed the 20,000 view party. Hope the beer and pizza was satisfying
Thank You for this info educational vid
Your welcome. What is your motor out of?

Should the valve clearance be set with the motor warm and not completely cold?

Hello, I have a question, although I have made all the connections correctly, the engine does not stop, which part may be defective?

I'm going to try and put a new carb on it and see if that changes anything. The valves were where they should be.thank you for your feedback.
Need to have it pressure tested, should hold 7 psi
If not replace seat and needle
@@philliphall5198 wondering what you use to pressure test the needle and seat?
@@philliphall5198 how do I do that ,by putting pressure on the fuel inlet of the carb?
the triangle arrow on my flywheel is not on top dead center, is this a bad thing?

@@autotech4103 pins are lining up, I think its the timing because it also has alot of pull back when i try to start it
@@tsurikawa6667 the pull back when your trying to start is usually improper valve clearance. Recheck to make sure it’s correct.

Hi good afternoon sir
Can I help you with something?
Can you teach me Can i come to learn from you
I teach at a high school in Manitoba. Come on down………
Please traducción a spanish
I am looking into this. Thanks for bringing it to my attention
