D_Mac 8,610 #51 Posted June 10, 2023 At the end of the line on the 310-8. Cleaned the screen in the tank, pulled fuel line at fuel pump, it is pumping gas. Fresh ethanol free gas in tank. Fuel flow is good. When engine cranks over I notice it spits gas from barrel of carb. Still won't start. Need help from you experts as I have no other ideas. Calling out for help.!!!! SOS !!

Pull the spark plug and see if its wet, maybe fouled .Sounds like you're getting too much fuel, flooding out. Take the bowl apart and check the float isn't stuck.

I've had 4 big block Kohler engines with 4 cheap carbs and all 4 were junk. The isavetractors carb John bought for the backhoe before I got it is working fine. Ill agree.Those IST carbs are some of the same available on flabby bay and the jungle store.Their just not quite the same as original OEM carbs. 1 Share this post Link to post Share on other sites

Eric what do you use fro solvent/cleaning agent in the ultra sonic cleaner. i used purple power but it seriously discolored the carb body and every time you touched it you got gray on your fingers. 2 Share this post Link to post Share on other sites

I tried using a product called Incredible Pink. That worked well but left the film you speak of. The pics above are when I used gasoline. I found that to be a good solution. 1 Share this post Link to post Share on other sites
Pete D 83 #60 Posted July 8, 2023 My $0.02: Purple power is strongly alkaline and should not be used on aluminum. Gas has a low flashpoint and terrible fumes. I like mineral spirits. Much higher flashpoint, very little odor, and works just about as well as gasoline. 1 Share this post Link to post Share on other sites
