I just rebuilt the carb on my 78 25hp....everything is great except the idle. It will fast idle in neutral, but the minute you slow down the RPM to the shift setting or lower the popping begins and will kill the motor. (New power pack have been install just two months ago with good spark.) I adjusted the low speed needle valve but that doesn't make much of a change. It is almost all the way out to get it idle some what.
I put it in some paint thinner for a few hours because I could not get the main metering tube out of the carb base and remove the plastic vanturi. All passage ways were blown clear with my compressor. I wanted to put it in some good old carb cleaner, but no go with the plastic in place.
The duck season is here and I need some help or advice? I can't trust this to run the river if it will not run correctly.
Can you get a new replacement carb for this year and model?
Thank dp
