New member here, need help and advice.
1. I have old STIHL FS80 trimmer that I want to bring back to life.
2. Don't ask WHY I want to repair it instead of buying new. Ok, I will tell. It's a challenge now to make it run! Plus, I like how sturdy it's built and feel bad about throwing it away.
Now details on what's going on.
1. It has older style TK carb with a slide (last picture)
2. I did try to replace gaskets, got fuel pump going, got it running but it was spitting out fuel out of overflow.
3. By doing some research I figured this carb has built-in valve that is non-repairable.
4. STIHL used to sell re-carb kit with adapter and new carb. Not anymore and was expensive.
I want to re-carb it myself now. Couple questions:
1. I guess engine is the same and I can use ZAMA carb from newer FS80 (new carb on picture)
2. What is the best place to get those kind of parts?
3. I will be machining adapter plate (carb to cylinder) out of aluminum. ZAMA carb has 2 holes in it. One for engine pulse for fuel pump, what is the other one? Also small hole(#3 and #4 on picture).
4. What is the proper orientation to install carb? Bulb on top/side/bottom?
5. What is the proper fuel hose arrangement? Old tank has only one hose coming out and it has pump bulb on it. I assume I will have to take it out (valve) and run hose directly to carb. What is hose #1 and #2? My newer trimmer has 3 hoses. One for fuel, one for return and one has small thingy on it. Breather? Do I have to do the same kind of arrangement with my re-carb?
6. I will have to get small filter box (with built-in choke). Are they pretty standard? What is the best place to get one?
Any other suggestions?
