What's on your bench?

I should have taken more photos but it's done!

Also this weekend when it was -31* F I got my old ice auger running again. Plugged the decomp, fuel line and modded the muffler and threw a 350 husky carb on it. It has a 49cc Tecumseh, the original carb was fixed jet and super small.

There was a piece of fuel line and there was a broken thread on the carburettor mount. I still had to look at the ignition guide and make the first cut :-D

On the bench now for an attitude adjustment.

One of my plans this year is to start adressing some of the mid range Homelite saws I own, the big 6 cubes are perfect runners when they need to be but I really would like some reliable 3-5 cubes ones to run along with the big ones.
First things first, I'll be doing seals for at least 3 Super Xl-12s and go from there.
There's a few aftermarket seal options now so I didn't have to mess around with 40yr old seals or hunting some elusive crossover.

I don't know for sure but my guess would be cubic inches, like a 4 cube saw would be a 65cc saw.

Yup, Saws from 65-82 CC's. Probably used more to mean 60-80 CC's.

Yup , as Ron and others pointed out a 3 cubic inch saw would be in the 50cc range ,4 cube would be 70cc and 5 would be 80cc-90cc .
I suppose I could have stated 54cc,58cc,77ccand 82cc for Homelite specifically.

I have a GX390 clone that is kicking my butt. Fed by a fuel pump, for the last couple of months it has been dumping gas into the oil. I have had the carb off a couple of times. Float bowl is pristine, float has no liquid in it, pivots freely, needle valve, seat and spring look good. Runs great at full throttle, starts okay most of the time, but fills the sump with gas at idle or while ignition is on and I’m pulling the cord. Nothing has changed with the pumpitself, it’s been on there for years working fine till recently.

Is there a pop off type test for a float bowl carb? I know a full bowl should seal the valve, but if is not holding pressure, how do I know it is not half empty and calling for fuel?

I’m about ready to give up and just buy a new carb.

Does it have an impulse driven fuel pump?

If the pump bolts to the side of the block, and has a rod that is cam activated, the pump is leaking fuel into the crankcase. If electric or gravity, the needle is not holding or the float has a hole in it.

Electric pump pulling from a belly tank. It’s a transplant into an old Deere AMT replacing the original Kawasaki engine with a cracked case.

The float is not leaking per the shake test. Must be the needle. Looks to be ~$25 for a knockoff carb to go on the knockoff engine.
I’m no quitter so I kinda hate to toss in the towel but I’ve already spent more than that in time and cuss words.

Looks like you need to get into that carb. Toothpaste on a q-tip in a drill on the needle seat, and make sure the float is not full of fuel and floats. Submerge in water and look for bubbles. Carb might just be dirty.

Got a 390 all together and all oem minus some heli-coils! Lol and an all oem 372xt to oe conversation! F China! Lol

Built a ms 440 and decided to do something a little different, took me about 5 hours to get the colors just right. Fresh rebuild using oe. Parts, plastics were AM, no real steal covers were hurt in this process.lol, still waiting on some parts to come in.

Wonder how bad it would have looked if you got the colors wrong.
