I discover a timing hack for digital ignition engines.
Setting a big gap between the coil and magnet will advance the timing. I tried it and checked it with my timing light. I get 4 degrees of timing advance at 4,000rpm.

New mod, I put a velocity stack on my gx390. Now it sputters and dies as soon as I touch the throttle.
I'll put the next size bigger jet and the next until it runs normal. I didn't think a velocity stack would make that big of a difference.

With the stock intake it was running great with a #100 jet. Put the velocity stack on and it needed a #105 to kind of run. Today it was being needy and would throttle up without a little choke. Think it needs a #108.

I found a dipstick oil temperature gauge for Honda engines. Stuck it on the gx390 and it hit 260F on a 80f day. On a 100F day that could be 280F oil. A bit hot.
Might see if I can rig up an oil filter/cooler with an external 12v oil pump.

I'm starting to imagine this with lots of brass and gears and big gauges and levers.

I use copper lines and brass pipe fittings and nipples.
