I took it off and measured last night. Came in just around .750 or 19mm.

Thanks. I'm in the ebay market for Honda or clone carburetors for my upcoming engine projects. I have one that's 18mm for my Briggs 5 hp, and I have my eye on a GX160 carb for the Briggs 3.5.

It's time for winter building projects.

Well- Curiosity killed the carb- almost. I couldn't handle that "non-serviceable" pilot jet staring me in the face. I carefully hacksawed a slot through it, hit it with a blast of heat with my soldering iron to break the locktite, and put the ol' flathead screwdriver to it.

All I did was break one side of the "head" off. AAARRRGGGHHH!!!!
Locktite, my arse- I think they welded it!
If I cut any deeper to try again, I may damage the carb and render it useless. I guess I'm just going to use the other one. I want the adjustability.

If it isn't broken, don't fix it.

I'm going to be modding this engine- The adjustability would have been nice. It's okay, I have a nearly identical carb with an adjustable pilot.

They don't want you tampering with their stuff. Maybe try some easy outs? It may be red lock tite, the engine kind that can take serious temps.

The heat from my soldering iron didn't touch it, I may try something else. I don't want to KILL the screw because right now it is still a functional spare carb. I have a fistful of extractors, none that small. Rats. I'll try another heat source tonight and if it still nets me nothing, I'll give up and just switch to the other carb.

I probably will. Right now I have the spare carb on, and I'm working out the new governor-less throttle linkage.

You can see that the dog knows which way is up. He's sleeping on a towel.

Folks, this isn't The Great White North, eh? I get the same weather patterns as New York or Michigan!

The shop's heated with a woodstove. Not worth the wood and effort fo a bit of fiddling around. If I'm working in it all day, then yes. Now? No.

Tore open the case today and removed the governor guts. I won't do a how-to, as it's been covered extensively. A few notes on the task for those a bit short in the homework department...

1) There's a wire circlip retaining the governor gear. It's a PITA to extract this ring deep in the case with everthing else in the way. What worked for me was two flat screwdrivers tip to tip in the ring groove, then twisting the drivers away from each other. The clip will spread open and fall out of the groove. It's not a snapring, so snapring pliers wouldn't work.

2) The governor arm does not have enough clearance around it in the case to come out no matter how you orient the crank. I found it best to push it as far up out of the case as possible, then cut it flush with the boss using a hacksaw. Gently drive the remainder back into the case using a punch. Watch for clearance, you may have to rotate the crank, but there IS enough room with the arm being 5/8" shorter.

3) The hole in the top of your case must now be sealed. I drilled it open more with a 17/64" drill bit, and tapped it to 5/16-18. I wrapped teflon tape around a 5/16x3/4" bolt and sealed the hole that way. Here's an interesting thing- I may run a diaphragm fuel pump in the future. On a whim, I took a 1/4" barbed, brass hose fitting and ran a 5/16-18 die over it, threading it. Because of the barbs, some threads are deep, some are not. But I teflon-taped it and it snugged in the hole quite well. When I'm ready for the pump, there's my pulse take-off. I would have preferred a 1/8 NPT hole, but I don't have the required drill and tap.
