ineedanother 1,366 #2 Posted June 30, 2023 Fuel. I would be curious as to how long it's been sitting and what the fuel looks like. Drop the bowl and have a look. I don't see the fuel filter. That's a long run for fuel line so if it hasn't been replaced in a while, consider that along with moving the filter as close to the carb as reasonably possible. You might need to do a cleaning on that carb. 3 1 1 Share this post Link to post Share on other sites
SylvanLakeWH 24,316 #3 Posted June 30, 2023 Rec fuel. No ethanol. Purchased couple months ago. Used it all last winter to push snow and was in the Memorial Day Parade couple weeks ago... Fuel line / filter was replaced about a year ago. @ineedanother Thanks for the input. will check those out. Share this post Link to post Share on other sites

I live in a county of more than 325,000 and there's not a single source for non-ethanol. Share this post Link to post Share on other sites
SylvanLakeWH 24,316 #6 Posted June 30, 2023 Just cleaned it up and purrs like kitten. Few shots of carb clean after to get the cob webs out. Gonna change the filter too. It's just above my marine bulb... Thanks for the help. 2 3 Share this post Link to post Share on other sites

Try to locate a lake or river with boat traffic and check gas stations near there. That is usually where you can find the non-ethanol. Might be worth a drive with some jerry cans. 2 Share this post Link to post Share on other sites
