Hello all!
I was given a 2000 Suzuki Quadrunner 500 (Quad 500 Runner?) and its current state is a bit of a mystery!
Kept indoors but hasn't been run in 5 years. We're not trying the engine until the gas is replaced, and the tires are reinflated. But the previous owner said their only issue was stalling when shifting to reverse without giving some throttle.
I'm optimistic! See y'all around!

My 2004 Yamaha Grizzly 660 seat is a mess, torn up, cracked, and I have been duct taping it for a while. I bought new vinyl for $35 and need to do it one day. A new seat used to be well over $250 but now its under $100 so I couldn't resist. I got it on ebay with a 10% off coupon for $85.05 plus tax. https://www.ebay.com/itm/146040022154
In case anyone is looking for a new seat for their Yamaha Grizzly 😁
I saw it on Amazon as well for under $100

Hi everyone i am coming from Europe and looking forward to join this community. I'm currently riding Kymco mxu300r which is the same bike as Brute Force 300 just different plastics.
Recently i came to a problem with this atv when accelerating near full throttle it suddenly lost power like i quickly released throttle but i kept throttle lever in the same spot. Since then it pulls off fine until you are past first 1/4 of throttle and then starts stuttering/misfiring. Same behavior when revving in neutral or riding. Cleaned and gapped spark plug but no better.
Could this sudden symptoms be from bad ignition coil and cdi or dirty carb? Carb was never cleaned before but i used stabil in gas when atv was not in use. Atv has 1000 miles carb on it is Keihin cvk32.
Sorry for longer post and thank you in advance.

Hello everyone. This is a Go Cart and not a typical "ATV" but it has an engine so I'm hoping someone can help me. It's a Helix FTX with a Manco 150cc engine. The engine will start and idle for awhile, but will not take even a small touch of throttle. Stalls. It seems to take throttle and rev up when you first start it cold, but in just a minute, it will not take any throttle. I've replaced the Fuel valve/Pump on the fuel tank with no joy. It's a nice little cart, but without a workable engine, it's a boat anchor. I'm not dumb when it comes to small engines, but this one has me stumped. I'm running out of options.
I'll mention that while it is idling, it will sort of "cough" every 6 or 8 seconds and then recover and idle again. Eventually one of those "coughs" causes it to stall. It will start back up pretty easily, but as I said, it absolutely will not take any throttle and then it will cough and stall a minute later. I thought it could be timing, but there is no "adjustment" for timing on this engine. I downloaded the user manual and it mentions nothing about timing and is pretty much useless as a service guide. It just shows the basics. I'm attaching the manual so you can get an idea of the machine I'm dealing with.
Any input would be greatly appreciated.
Kind regards,
Don
