My 325 mag 2x4 after shutting it off after it has been run for a while is hard to start, gas bubbles out the over flow tube.When it does stat it takes a little time and then it runs ok.
Any thoughts at what could be wrong. I was trying to check out the oil cooler fan because I thought it maby is orer heating but don't know how to bring it up to temp to get the fan to come on. Has anybody had this kind of problem?

 

You might see if the fan is even coming on, right now I have trouble with my fan not coming on, I have yet to find the problem, It is electrical though.
But what I'm saying is, if you think it is the temp of the motor boiling gas, then maybe the fan is not kicking on, and trust me, that motor can get VERY hot.

 

My wifes is a little differant, It is hard to get started when it has been sitting for a week or so. After you get it started and it is up and running it starts all day just fine. Its not like it's cold or something as it is over a 100 degrees here all the time. Hmmmmm
