Tillotson Carb Problem
Hello Guys
I have brought a used Stihl chainsaw for conversion and it is around 56 cc engine and first of all i give it a test run and it works fine and the carb is sucking the fuel after that i have decided to start conversion and i started off by rebuilding the carb and it does have a Tillotson Carb on it so i opened every part of the carb and cleaned it with gas then i have reassembled it and put it again on the engine but then the engine does not start and i have noticed that the carb is not sucking the fuel and when i dip it in a transparent fuel bottle it was just giving pulses
so can any body of you tell me that what is wrong with the carb
waiting for your suggestions

Unless you are messing with the old carb for sport I suggest just getting a new one.

RE: Tillotson Carb Problem
The gaskets are in good shape? (not ruffled, split or curly) and you have them back in the correct orientation?
The pulse port from the crankcase lines-up with the pumping side cover OK? i.e. the carb fits to the manifold the same way it came off?
It may be as simple as:- If the carb is dry now, you may have to prime it. Completely cover the intake (with your thumb or palm of the hand) and then turn the engine over. The choke by itself will not prime a dry carb.
Good luck!
