I have about 6 Victa units all with various problems. One inparticular that is bothering me is that although I have replaced the entire carbi, being a G4 plastic black carbi, i am still able to start the unit but it sticks to an idle type rev and appears to starve for air. Is there anything I need to look at changing at this stage.
I also need a diagram for the metal carbi system and how to properly assemble one for another unit. Is this available via the internet or do I need to buy a service manual?
I have also a TWIN 170cc unit that is very hard to start as in I need to pull the cord several times constantly so that the revs keep building up. Any suggestions ??

If the engine fails to run above idle, it may be that the governor link and the throttle link are reverserd on the carb. Be sure they are in the correct holes on the carb. throttle plate. Check the positions on another machine to verify.

Another possibility to check is the governor linkage position at the other end of the carb. The actual governor, inside the crankcase, has a shaft extending out of the crackcase with an extention rod with holes in it. The governor linkage end from the carb. must be in the correct hole in this rod also. check another engine for the correct location once again.

If the engine seem's to run starved for air, check the high and low speed fuel screws. Be sure each is turned out the correct amount. The engine may be running too lean and not out of air. Also check for any air restrictions from the carb into the cyclinder.

Regards and Good Luck.
