Re: New Honda 2.3 outboard not running
I forgot to drain the gas from my Honda 2HP. The next spring, no go. The bowl was full of debris, almost like sand? I did two experiments:
1. Let half a coffee can of treated gas evaporate in open air. After a number of months all that was left was a little bit of what looked like 90 weight gear oil, which never went away.
2. In an old carburetor, I left the bowl full of treated gas with the carb assembled. After a month or so, I took it apart. There was absolutely no evidence of any deposits or debris, it was perfectly clean.
Perhaps there is a difference in the gas evaporating in open air and the gas evaporating in an enclose area such as the assembled carb?
In any event, I always drain the carb if it is not going to be used fro a week or so, seems to work, no problems.
