Why use the 199 on a 346xp?

[shorthunter]

I have a 346 here with the 154 carb. It seems that everyone wants a 199 carb on their 346, my question is why?

The 154 has a 15.08 mm venturi, the 199 has a 16.66 mm venturi. Why not just thin the shafts on the 154 to get the extra flow

For bragging rights, even though most don't test before and after. IMO

it really depends on the porting. if you raise the whole port and widen it , you can get more fuel in faster and trap more. increases case pressure

Would a 154 with thinned shafts work the same as a stock 199?

without changing the whole intake system. yes

There is a 346 in Mo that has a 372 carb on it... Jus sayin.

And it is the fastest 346 I've ever run!!! It smoked my ported 357. Hahaha

There is no bad side effect to putting a larger carb on a 346.

I had a dozerdan OE 346 with 199 carb. In cookie cutting it was 10% faster with 357 carb then with 346 carb.

In the real world cutting firewood etc it dont mean squat IMO. The wood will never know the difference in the times.

I have the cut times saved from my testing. I will dig it up.

Also 199 191 175 (might be a few more that is the same) carbs can be used if you feel the need. Not really needed unless cutting for times.

Have seen even bigger carbs on 346. Thinking a HL, 066 carb. Seen 084 on a 026. Heck had a 272 on my 5000.

I don't see any real differences in the saws I build. That might be because of the way I build them.......I'm not sure.

Like Shawn said........most guys wanna be able to say they've done all they can. Bragging rights.

I feel the difference, but it's small. There will likely be no gains on a stock saw though.

Never even heard of someone doing it to a stock saw. I wouldnt even consider that.

Reason I say that on a stock 6700. I took a 6700 carb off put on a bigger 8000 carb on a stock saw. It felt stronger by the seat of the pants. But was it, I dont know. I pulled the carb off put the 6700 carb back on and the wood couldnt tell the difference.

I just sent out a Jonsered 2150 with a 346 jug and an HD12
