Not sure what leaking over means...... But here is what little I know. If you pressureize the carb at the intake to about 15 psi you should not see any drop in pressure. If there is a drop in pressure put it in water to see where the leaks are. Usually it is from one of the gaskets. But...

I ended up testing the saw again and noticed that bubbles would come out of the little channel. It was also leaking out the oil pump where you would take out the snap ring. I replaced the rubber seal for the pump and it works fine. Thanks for all your help.

Thank you for the service pages. I will take out the worm gear for inspection and if that checks out ok then I will replaced all the oil pump seals since the pump itself looks ok. So to get the worm gear out I just spin the cover plate backwards. Almost seems to easy, I am surprised I...

Fuel lines are in correct positions. I did try to lean out the low mixture but then it would be slow to throttle up. I have tried several positions with the low mixture then tipping the saw up on its side and the rpm's still flucuate. I ended up just turning up the idle so that the rpm...

something new to me I just started working at a new repair shop and they said they had the same problems until they started cleaning the carb parts in a sonic cleaner(similar to jewelery cleaner) They said it has increased the percentage of carbs taking the rebuild by 50%. I have used it...
