Had a gx390 backfiring bad. Exhaust valve was extremely off. Adjusted it and it fired right up. Thank you for the easy to follow video. Now I need to get my hands on a 1/4" torque wrench. Thanks again!

I put a finger on the rockers push rod end just to keep it well seated while using feeler gauge.

Great job. I have a Tecumseh HM100, (10HP) gas engine. Great shape. Would like to convert to electric start, but can't find a conversion kit. Maybe another manufacture would be ok. Any suggestions. Thanks

I realize you belabored the compression stroke but you lost it when you went to the arrow. The arrow aligns also on the exhaust/intake stroke transition. The way you mentioned the marking might have been slightly unclear.

How do you be certain the Compression release does not engage ? .....it is spring loaded to engage at low RPM and tightens up the exhaust valve ....

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?

Thanks, right to the point.

my gx340 exhaust valve open slightly after intake valve closes during initial compression stroke to halfway compression stroke, is that normal?

@jtkasprick 10 ай бұрын

The exhaust valve could be set to tight. During starting there is a decomposition valve that will open the exhaust vavle slightly during the compression stroke to aid in starting. I do have a video on that on my channel.

Great video Jeff, when i go to pull the motor to start it, it rips the cord out of my hand so much so its dangerous bloody whipped my hand, why does it do this?

@jtkasprick Жыл бұрын

That sounds like kickback. If the fuel and air ignite before it reaches top-dead-center on the compression stroke it could force the piston back down reversing crankshaft rotation and pulling the recoil cord from your hand.

So on my 4 stroke stihl weedeater when you adjust valves you spin the engine over until the arrow on flywheel is lined up with the ignition coil, and you wiggle it back and forth to make sure neither of the valves are moving, is this the same concept on this honda?

@jtkasprick 4 ай бұрын

Exactly!

@shadymaint1 2 ай бұрын

That is still a 2 stroke engine. Yes it has valves like a 4 stroke. Stihl calls it a 4 mix engine. Yes you do have to adjust the valves periodically.
