I got a question ..... do you guys close your gas valve on the sleds when traveling ? My dealer told me this could fill your block full of gas & pipes is this true ? he told me that on newer sleds they have an auto shut off . What do you guys think
I saw a friend blow an engine last year by forgetting to turn it back on. He started and blasted down a runway and when the engine ran out of gas it burned the pistons and rings. He was dumb to go and run it cold like that but im the kind of person who might forget to turn the valve back on so i just leave it on.
I have trailered almost 6 hr every weekend and never had a problem so i am going to stick with it.
im with mxz7 if your needle and seat are working right no fuel can enter the engine if it isnt working right you would know it the engine would be running rich all the time and you would be fouling plugs like craze if you dont have these problems then dont turn the valve off
Well every one seems to believe those valves are ther for nothing!?
And contrary to popular belief a working needle & seat won't always stay "sealed", temps, trailer angle, bouncing floats!, iced closed tank vent!, can all cause "leakage". Of coarse it doesn't always happen but when it does just being hard to start is the best symtom you might end up with, "hydro lock" & bent rods from trying to start your motor filled with fuel are wurst case(not very common but I've seen it happen!
Yami's are supossed to have a fuel pump that seals?, with out vacum, maybe some of the other brands are also using that style pump & a petcock also?
If I think of it I shut it off, but most of the time I never do.
Don't you guys run your sled then shut the fuel off and let it run out of gas for summer storage? Or do you leave fuel with stabalizer in the lines all summer?
i allways shut the fuel off on my mach z. i had a plus x one time that the floats stuck on it and it gravity fed and ran a ton of fuel out the overflows. our new 800 mxz doesnt have a shut off, i`d feel better if it did
See the reason I ask is because when I brought the sled in for service , '' for no spark '' The guy told me the block and pipes where full of fuel , and they where .... and when the sled was running the rpm's would drop you have to stay on the gas or it would stall , and once it done that you could pull and pull and the thing would'nt start .... ! pull the plugs and they are wet .... no spark .... change them still no spark . But if you grab a plug and pull it over ... it has a little tingel to it ..
