Looks good lots of pull for a little guy

We ain't done yet fellers.

That jug just came back off.

if we could figure a way to feed it a little more ,it would be a bad little mofo

randy,
yer sneakers are full of sawdust/chips !!

It's not running lean......I really think less fuel might be what it needs. :msp_ohmy:

What happens if you pull the air filter, will the carb instantly make the adjustments and feed fuel? How far can the carb go before it won't feed enough fuel. I know they will adjust for an air leak, but that is not going to work if it already flowing at its max.

Huskys autotune system will provide enough fuel to flood a ported saw out when they have an air leak. I figure this system would be the same.

I'm moving on the just leaving the strato system intact and porting it that way now.

I wonder if you did not do the recalibration if you would have had similar results as brad?

I didn't look at Brad's thread much at all. What results are you referring to?

 

[blsnelling]

Did you remove the plastic divider in the carb venturi?

I re-calibrated for each mod.

Of course not. That would throw all the system's calibrations out because it would racially lower the signal at the fuel nozzle. :msp_confused:

Of course not. That would throw all the system's calibrations out because it would radically lower the signal at the fuel nozzle. :msp_confused:

Fixed.

Righto. :msp_thumbup:

The carb would not provide enough fuel to run.

No, I didn't see that problem.

That would explain why it runs. But it also explains why it didn't make much difference in power. You're still only adding fuel for half the volume of air going through the carb, then allowing that to mix with the fresh air from the bottom half of the carb. In order for gutting the stratos to make sense, you must provide fuel for all air going through the carb.

You're saying the saw is getting twice as much air and only half the full it needs? Wouldn't it be incredibly lean, if that were the case?
