The above is the start of this thread actually but has since moved from crankcase full of gas to the subject of carburetor rebuilding.
We did remove the carburetor yesterday late and got the shop trailer cleaned up with the work bench space clear. Because we had to spend the afternoon doing some fencing and gate installation so the mini horses could gain access to the dry if they choose this winter it was 9 PM before I got to touch the carb.
We did get the diaphragm, float and all removable jets out of the carb tonight. The rubber tip on the float shut off needle was shot for sure. Had one jet that is recessed that I was concerned I was going to strip out the screw driver slot but after letting some PB Blaster soak in the hole I finally got it out. I think the treads were dirty.
The main jet was a 145 size. The moving parts showed some wear and it was dirty on the inside especially under the the pump diaphragm. I think a rebuild from time to time is good so one gets the carb very clean on the inside. With the jets, needles and float out one can get the carb cleaner blasting through out the carb passage ways. The O-rings were in bad condition too.
One thing that I have learned so far at least in the Magnum series that 89 octane gas is required unless it is alcohol free then 87 is permitted. The second thing from the manual is running an engine too lean will toast it over time.
