What's on your bench?

[Lightning Performance]

The bench is being built to fix my stuffs.
What should the bench top wood be make of?

Locust, maple, oak, be specific and state why you think it will be best for small engines. Two to three inch max top thickness. Three inch space below the top with double draws. Initial base will be 3'x5' portable wood frame. I have thick aluminum and mild steel plate for bench welding cover. White oak is the frame. I have 5/4 pressure treated oak plywood if needed.
First up is rehab 660's.

If it flies, floats or fuuks; its cheaper to rent than to buy.

Make two plywood tops. Now you have four surfaces...That should last about until you're done.

Your spot on....perfect. One sheet of the heavy chit will do it. The wall is going to be wood of some good looking stuff like the walls in a nice new shop in NY . Who did thOOse?

Too funny Curt, but so true.

EFI Kohler on an eXmark Lazer. No start, no communication to or from the ECU. The ECU, MAP, MAF, TPS, and Crankshaft position sensors all test good. Has a break somewhere in the engine harness.

Replacing the engine harness assembly, cheaper than trying to isolate the break.

My 28hp EFI seems to run lean all the time. When I'm done mowing the exhaust is glowing red. I've changed the fuel filter and the fuel pressure looks good. Any ideas mower guru?

Flywheel key partially sheared maybe, or possibly a bad Crankshaft Position Sensor? (Doubt the sensor, it probably would not run at all). It MIGHT be the Throttle Position Sensor, they can cause all kinds of weird issues but again I doubt it, they do not fail that often. Best guess without being able to see it is a bad Oxygen Sensor, ECU thinks it is over rich and tripping into a lean run mode.

I have a new O2 sensor, I'll swap that in and see if it gets better. I should be able to test the throttle position sensor with a 5v supply and a volt meter?

346xp piston and cylinder with a 359 carb and intake track??? Only seems logical to me.

I just saw ad for 346 P&C OEM $89.00 Or close to it.

Nice score! I really like the fs120 200 250, the fs250 cylinder is a bolt on! I did that to my fs120r, China cylinder and caber rings, it’s been a runner! I have an all oem fs250, and the China cylinder out runs it!

I honestly do not know sir, I always just plug them in.

That's what you need for your 345..........

Don't have any of those things
Do have 4 350 pistons
Echo bulk fuel line
A metal intake clamp
And a dremel
Worked it over
Just need the pad that rides on the throttle Shaft.
I'm giving this to a friend
He has fibromyalgia
It'll be easier to start

The alpina 600 i fixed a couple year's ago.
