I hope that I am posting this question in the right place.
I have a Yerf Dog 3203 that a friend gave to our family. It has a Tecumseh 6.5 hp OHH65 engine.
It ran pretty well except when you hit bumpy terrain...then it would briefly stall and then catch and fire back up fine. It was disappointing but still fun to ride.
Then my nephew rolled the kart and it took awhile to repair all of the "minor" damage (axle slid over about .5 inch to 1 inch so that the rear tire rubbed the frame and the gears for the chain were misaligned - that has been fixed).
Now, whenever you hit bumpy terrain, it is definitely running much, much worse - it stalls really bad and sometimes completely dies...if you play with the throttle a bit, it will sometimes continue to run. A lot of times, it will just die.
It starts fine, idles fine, and takes off fine...over flat, non-bumpy terrain, it runs pretty good...sometimes it will stall very briefly at WOT but runs pretty strong for the most part...you notice a real problem when you hit any portion of the property that is the least bit bumpy and the problem is almost immediate.
These are the things that I have done to try and fix the issue:
1) The rear clip of the gas tank broke so the gas tank would flop around a bit...I used a zip tie to tighten that down so it no longer flops around.
2) Replaced spark plug - not because I thought it was the problem but because it really needed replacement.
3) Replaced what I thought was a fuel line running from the carb to what I now believe is the pulse fitting on the OHV? I replaced it because there was a lot of dust buildup around the carb near that line and while it was still connected, it slid off and on very easily...just assumed it might be creating a vacuum issue of some sort.
4) When I replaced the part in Item #3 above, I managed to kink the actual fuel line from the gas tank...or maybe it was always kinked...I don't know...the kinked part of the line was cut off and there are no more kinks but it seems to be a very flimsy fuel line. I was considering replacing this with a sturdier fuel line...is it possible that this might be contributing to the problem?
After Steps 3 and 4, it starts much, much easier now but still cuts out over bumpy terrain.
A friend of mine thinks that it might be the float in the carburetor - is that something that might have been damaged worse due to a rollover?
As you can tell, I'm a total newbie when it comes to engines of any kind (see Item #3 above for the evidence).
Any help or ideas would be greatly appreciated.
