rhino fuel pumps

[rotormech]

anybodys rhino hard to start when its cold,mine will just turn over and wont fire,like -10 and lower,then if you come back and try again it will just fire up,it seems if you dont start it for awhile it takes a long time to fire up.could it be the weak fuel pump?or carb isues,it start fine all summer...

Might need a choke adjustment. To start mine I pump the pedal a couple times, pull full choke and start. Then I let it 1/4 choke, it will stall then it will start right up the second time usually with no choke.

I found after I installed my CDI it started better, THEN I rejetted my carb and it improved even more.

what did you do for a rejet from stock,i have a aftermarket cdi too?

I added a 2" exhaust tip and 2" intake snorkel

If you want sometime, you can have a look at my machine, I have it at work on the north end of town. Just heading into town to go "shopping" with the family..

That's a pretty common issue. You can put in an electric pump to fix the problem. What I do when it's cold and it hasn't run in a while is pop the cowling and put my hand over the snorkel to "choke" it, this cut's the cranking down quite a bit.

It also helps to run a 0-40 oil like Amsoil, I found my machine turns over way better in the fall while out hunting.

installed a block heater .. Never had any issues since

 

[rotormech]

what kind of block heater did you use?are there actual frost plugs?

 

[mudboy]

They are actually for yamaha snowmobiles. Any yamaha shop will have them. It is just an inline hose mount coolant heater. I will check and see if I still have the part number somewhere
