Backfire - Same old Story

rugerm77 · 07-03-2013, 08:09 AM

1997 EZ-GO 295 Robins , New Carb. Fuel pump , It's been running Good but 2 days ago my Grand-Kids was driving it around in the back yard & it went to backfiring out the muffler , Yesterday it started even more .
Will only do this at slow speed or when you give it more gas.
Adjusted the valves to .004 when motor was hot & played with the carb. a little , also checked the gap on the new plugs . One plug was Dry but One was still Wet ( Firing Problem ) ?
I'm thinking it has something to do with the carb. but I don't Know
Tried to get to the Timing belt but to do that I'll have to pull the clutch which means pulling the engine because I don't have enough room to get the Clutch Off. Help

Make sure the throttle plate is closing all the way. Also, make sure the ignition comes on just prior to the throttle plate opening. You can adjust the throttle linkage to make this happen.

Gonna give that a try , but can't understand why it would just start doing All the Backfiring , Ever tank of Gas is treated with Star-Tron.
I can fix a Sparky in my Sleep , But this Gasser is making me loose Sleep.

i set my valves at .007 cold it will start better cold. i would check compression in the hole with the wet plug. then i would check to see if it has spark

Two Weeks later & I'm still having Backfire problems , can't figure this thing out.
It will backfire whe I'm giving it gas untill it gets up to full speed then start running good.

Well I can't believe it - Thank you Marathon - With these Gas Carts I've got to Quit thinking Big Problems & start off Small ( Throttle Linkage -That's It )

Only other thing is the Wet Plug , Checked Compression on the wet plug Cylinder & it's running 147 , I guess I'll have to Pull the engine ,Remove the Clutch & check the Timing .

Well , FedEx just delivered me a new coil for this Backfiring Beast , I put it on & and Man was I shocked , That Beast fired Up & runs like a Scalded Dog , ( No Backfire - No Hesitation - Power out the Wazoo ), This is one HAPPY Redneck. Thank You Jason's Carts.
