text: SOLVED: I have a Toro s - Fixya
  I have a Toro s 200 model 38130 1979 snowblower. it would not prime no suction when bulb pushed. I replaced the diaphragm with a kit diaphragm first to carb etc. along with new needle valve and spring. Now I get suction...it primes ...won't start and gas leaks out of bottom of diaphragm housing on Walbro Type F carb. Good compression and hot spark. Did not leak before R and R and gas flowed to carb but again had no prime. Can U help? I am too old and decripid to shovel No choice for snowblower so I picked car A

  Switch the gasket to the other side of the diaphragm. (i.e. if the gasket is between the carb and the diaphragm put the diaphragm between the gasket and carb. or vise versa) should fix the prob.
  Replaced the compressor after the old one made so much noise and now the new one with 35/200 press. Does not get cold. What about the by-pass on the suction line. I'm not familiar with anything like that....
  No thing as by-pass on suction line, your reading of 35/200 are good, is that at 2000 rpm, did you evac the system, or it will not cool.
  6hp toro snowblower. cleaned carb, reinstalled all parts, engine ran for aprox. 10-15 seconds then shuts down. appears to be straving for fuel. push primer button and it will start up and then shut down
