STIHL ElastoStart is a special starter handle which ensures a smooth starting process without any sudden peak forces. The integral damper smooths the power profile that is generated during starting and makes the starting process a lot easier.

Features

Stihl fs 46 carburetor adjustment

Standard features

  • STIHL ElastoStart

    STIHL ElastoStart is a special starter handle which ensures a smooth starting process without any sudden peak forces. The integral damper smooths the power profile that is generated during starting and makes the starting process a lot easier.

  • Shoulder strap / carrying system

    Using a STIHL shoulder strap or carrying harness with soft padding makes work more comfortable, particularly during lengthy jobs.

  • Compensator

    This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn't need to be cleaned until an appreciable drop in power occurs.

I have a lightly used FS130r that's been running great until recently I couldn't get it to barely run. I changed out the gas for some unopened Stihl premix gas but it didn't have any affect. I noticed that it was leaking gas out the air filter. I took the carb apart and didn't find anything wrong, but when I put it back together just priming it with the bulb would cause it to start dripping. I couldn't find the source of the leak but instead put in a new Zama carb kit. This fixed the leak but when I put the H/L screws to 3/4 turn out as per the manual I could hardly rev up past idle with fresh 91 octane fuel. I had previously trimmed the plastic needle stops so I could use more adjustment. The only thing that would help would be to keep turning them out, and a lot. I finally got it to run very good but the screws are probably at least 3 turns out. It was running good at full throttle and I kept increasing the fuel on the H screw to see if it'll bog down but the screw finally came all the way out. It sounded like it was running good as long as it was backed way out though.
Is this normal to have the screws set so far out? Was the 3/4 turn out somehow adjusted with the stock plastic caps and that's what's confusing me? I'm lightly seating them and then screwing them out. Also I'm not sure why I couldn't get the High to have too much fuel to get that adjustment right on.
