Big Stevemo 3 #1 Posted May 7, 2023 My engine was acting like it was out of gas. But runs with choke on. So I limped it back to shop. Checked fuel flow. It was not good. Blew air through line into tank. It flows good now but still won’t run without choke. Can I pull the petcock out without taking the tank off? What else should I check? Thanks first post. 308-8 with M-8 Koehler. 1 Share this post Link to post Share on other sites
stevasaurus 23,274 #2 Posted May 7, 2023 Change out fuel filter if you have one. Check fuel flow on engine side of pump. Drop carb bowl and check for foreign material. Readjust carb. Welcome to Red Square 1 Share this post Link to post Share on other sites

Big Stevemo 3 #4 Posted May 7, 2023 Yeah thanks guys. Bunch of rust looking crap in bowl. Don’t know where it could have come from unless previous owner had rusty gas can. I would like to take the tank off but the Phillip screws on the top won’t budge. Are there inserts in the plastic tank? Any ideas how to free the screws up? 1 Share this post Link to post Share on other sites

Drain as much as you can from the tank and then get a good grip with Vise Grips and it will pull right out. remove the rubber grommet too. Use a bit of oil to aid the installation of the new grommet and valve. If you want to remove the tank leave the petcock in the tank while doing it. You can remove the rear fender, clean the area where the brace is bolted to the transmission and take out the two 3/8" bolts. Once the tank is off the tractor you can slosh a bit of gas or denatured alcohol around in the tank and dump it out the fill er hole. May need to do this more than once.

On the 308’s the tank is attached to the side of the motor and not under the rear fender. And they are a pain in the butt to remove. 1 Share this post Link to post Share on other sites
Big Stevemo 3 #7 Posted May 10, 2023 Yes. Tank is on motor. Does the petcock pull out like the other ones? 1 Share this post Link to post Share on other sites

Sparky-(Admin) 23,139 #9 Posted May 12, 2023 @Big Stevemo Took some digging but yes, it looks like it’s the same setup as the bigger under fender tanks. Go to page 33 of this manual. 1 Share this post Link to post Share on other sites
