1978 chrysler 4 hp is alive again!

[lucky4075]

hello

just today my friends and I started and ran my old 78 chrysler 4 horse for the first tim in about 5 years. we ran it in a barrel for about 30-45 mins. it runs mid and upper range very well, but it will not idle. when i back the throttle down slowly, the rpms will drop to a certain point then the engine will just slowly bogg down and stall out.
the fuel filter could use replacing, but would that be causing this?

thanks a lot!

Remove the fuel filter first if you feel it's the problem.

Next, Suggestions/Comments:

Have you disassembled the carburetor, soaked it in carb cleaner (B-12 etc.), checked all the passages for restrictions, and readjusted your carb adjustments? Was it running fine when you last ran it? Did you remove all of the fuel from the carb bowl and carb when you last ran it 5 years ago? Have you seen the affects of fuel or moisture after siting in a carb for 5 years? I have seen Stabilizer in fuel do a good job for 2 years but that?s the longest I have experienced personally. I have seen some carbs totally corroded after 5-10 years that worked after cleaning rebuilding with a kit. The rubber seats and gasohol has added a new twist since my active repairs. Recent repairs on lawn mowers related to starving for fuel at higher RPM due to swollen seats. Do you have a link of your model Carb showing passages, parts and adjustments?

Good Luck! Jow
