bern trailboss: I have same quad .. its a tank .. I love bigbear350
Dan Redmanfour: Thank you for the video good job. I have a 350 Big Bear and while I was trying to start the engine it would only run for a few seconds. The small of gas was very strong. I removed the seat and the air filter housing and ¼ of the housing was filled with gas/oily mixture of some sort. I keep the machine in the shop so there was no water in the system but it would not run very well at all. After removing the gas and cleaning up the machine I removed the crank case breather hose and while starting the engine it was running a lot better, but the hose was blowing gas and oil out of the breather hose. The longer I let it run the more gas came out until after 30 minutes it slow down and stopped. After 1 hour there was only a drop every two seconds coming out of the breather hose. The question is what caused it and what do I need to do to make it work better? I did let it run for about 2 to 3 hours. Any help would be great. Thank you for your videos.
kurtis fuller: Love my big bear to death!!! Its an amazing quad :)
isaiah armitage: yea my friend has a moto4 and we blew the transmission out of it and got a new one and it runs great
Jake Morris: I have a 86 moto 4 and I'm surprised on how similar big bears and moto 4s are. Great and helpful vid!
Todd Barnett: Hi donyboy73,
This video is so helpful! thank you so much for the tutorial. I'm having trouble finding a 1995 yamaha BB 350 4wd carb kit....Can you confirm that this kit will work MD03-304 12-9926? Yamaha stopped making carb kits for Big Bears in 92? I think. I'm hoping that one will work. Thanks for posting such helpful videos!
gbennettsenco: Great video,does the float have a adjustment?
phil78901: Good work and good job explaining! I have a 95 Moto 4 with the same 350 engine.
Tristan102100: my neighbor has one that looks like this except it is a 175,2wd...and that's about it other than that it looks exacally like this.
quintenc24: Thanks and also whenever,i turn the fuel switch on gas pours out of one of the lines. What should I do?
donyboy73: clean it with carb cleaner
quintenc24: Is there anything to i can to to fix a sticky float without buying a new one?
kimmidobbins: You have dirty pilot jet and or clogged idle mixture screw passage. Typicaly for something that dirty you will want to fully disassemble and soak the carb and its individual parts in a gallon of carb cleaner. Not the junk you buy in a spray can. The gallon of cleaner can be bought at any auto parts store and will run about 20 bucks.
tubemcg: Donyboy: Great video!
eatasammich: Mine will only run with the choke out any idea why?
DAVID wayne: Great video! thanks for sharing I rebuilt my carb and replaced the manifold It runs ok but it seem to have a pop pop at idle. can you help with that? thank again
