WANTED Husqvarna 385 or 395 throttle shaft

[Shane¹]

Looking for a tillotson throttle shaft for a 385, 390 or 395. Will take a whole carburetor for the right price. Trying to find a throttle to put in a carburetor for my 9000 hybrid project. I believe tillotson numbers are hs296, hs298 and maybe hs300?

Shane -

Are you going to be using the 9000 throttle rod or a custom linkage?

It's a custom cable but I already have it the right length for a 395 carb but want to try a tillotson hs carb

Maybe it would make more sense to just try a 395 carb again and rule out if I just had a junky aftermarket 1 the first couple tries

Are you looking to fit a bigger carb in the Dolmar 9000? Because those intake boots are pretty restrictive.

No it's an 084 cylinder with 395 boot with 372 intake brace

I am currently running a hs203 modified to fit but seems to lack power but trying to rule out if it's a carb issue or porting issue or it's just a junker setup. Just would like to start with a carb that should work. The 395 carb I first tried ran crappy didn't want to even rev up right. So I tried a regular 372 carb piss reved fine with that so I made the 203 and it runs ok just not as strong as I think it should so want to try a 9000 carb or try a different 203 but have an actual throttle shaft for it so the cable doesn't stick

If you're feeding an 084 cylinder, I don't know that a small HS carb is going to move that much fuel and air.

You could try adding a reed valve of some kind - that's how they made a smaller carb work on the Mac 125s.

It probably won't ever work I am just confused at this point why it runs better with a 372 oe carb than a 395 carb

The 395 carb may have an internal circuit issue or a bad nozzle. I've got a box of old HS carbs that I can dig through for worthwhile candidates after the new year. An RWJ-4 carb might work better there too.

I thought about a rwj4 the only reason I was thinking the tillotson was because I have a bunch of good 203s on 133/143 and all I would have to do is change the throttle shaft and top cover and good to go. The 395 carb was aftermarket and I didn't like how it ran on the 395 either that's why I took it off the 395 so I don't think it was a fair comparison that's why I was thinking a good 395 carb might be worth a shot. Should have tried the good carb I had before I sold the 395

I had one AM 395 carb that required some drilling of the low speed circuit to get it to run right. It was always lean at idle no matter the screw setting and therefor didn't accelerate worth a darn. I might have had to lower the pop off pressure too to get it to supply enough fuel at full throttle for more than a few seconds.

I have an HS296 (385/390) I can sell ya. I want to say the throttle cam is different on it vs the 395. Maybe that is just the Tillotson to Walbro though?

Do you have a picture of the 296 you can send over?
