bobcat Posted October 11, 2009 Share #1 Posted October 11, 2009 Noticed a funny odor coming from my bike...I discovered fuel leaking from the over flow tube from the right rear carb... Anybody have any experience dealing with this type of problem? (and how to fix) Thanks Link to comment Share on other sites More sharing options...
Monty Posted October 11, 2009 Share #2 Posted October 11, 2009 Try removing the screw from the bowl, and letting it drain...with the engine off. Then, spray carb cleaner up in the hole that the screw came out of. You seem to have either a float sticking, or a piece of trash in the needle/seat area. Maybe this procedure will clean out the trash, and the problem will go away. Good luck! Link to comment Share on other sites More sharing options...

Try tapping the carb with the handle of a screwdriver. I have done this once, to the slider cover & it had stopped. Link to comment Share on other sites More sharing options...
painterman67 Posted October 12, 2009 Share #5 Posted October 12, 2009 just had this happen to me and took out the drain screw,let it all drain out and then turned the key on (I did not start the bike) to let the fuel pump flush out whatever was in there then reinstalled. The bike even runs better now. I also added an entire can of seafoaminto a full tank and drove it till it was almost empty. Then ran a second can of seafoam throughout 4 tanks of fuel. Good luck.

bobcat Posted October 13, 2009 Author Share #6 Posted October 13, 2009 That's what it must have been, a sticking float..As recommended I removed the drain plug and turned the key on to flush the bowl..I replaced the drain plug and started the bike..No leak Thanks all for your help Link to comment Share on other sites More sharing options...
camos Posted October 13, 2009 Share #7 Posted October 13, 2009 I also added an entire can of seafoaminto a full tank and drove it till it was almost empty. Then ran a second can of seafoam throughout 4 tanks of fuel. Good luck. Rather than driving through a can of Seafoam better to use an equal amount of camp fuel which is straight naptha, the active cleaner in Seafoam. Unless the bike is a barn queen it is unlikely to need the second can of Seafoam but it won't hurt to put in a mix as recommended in the directions, which I'm guessing is probably about one can to 4 tankfuls. May as well save it for a beer or something less tasty but more useful. Link to comment Share on other sites More sharing options...

The old girl purs like a kitten now. David Link to comment Share on other sites More sharing options...
bobcat Posted October 13, 2009 Author Share #9 Posted October 13, 2009 I might add that I've been a regular user of Seafoam...I add about 1/3 of a can every other tankful.... PS....I like that idea of the camp fuel Link to comment Share on other sites More sharing options...
Condor Posted October 13, 2009 Share #10 Posted October 13, 2009 PS....I like that idea of the camp fuel Me Too!! Are we talking about 'Coleman'?? Might work better as a carb dip too. Sea Foam is good, but it's expensive. I wonder if the fuel could be used instead of SF??? Link to comment Share on other sites More sharing options...
camos Posted October 13, 2009 Share #11 Posted October 13, 2009 There is a thread on here about using Coleman or other camp fuel instead of Seafoam. Under certain circumstances, like a serious clean out, straight naptha should work as good if not better than Seafoam and certainly cheaper. http://www.venturerider.org/forum/showthread.php?p=367077&highlight=coleman#post367077 Link to comment Share on other sites More sharing options...
RossKean Posted October 13, 2009 Share #12 Posted October 13, 2009 According to the MSDS sheet, in addition to the naptha, Seafoam contains "pale oil" (a heavier hydrocarbon distillate) and IPA (isopropyl alcohol). The alcohol will help dissolve "polar" constituents and help get rid of water. The heavier hydrocarbon would likely behave as a lubricant. In essence, Seafoam's "active ingredient" is not simply naptha but the camp fuel would work well IF what you want to dissolve is soluble in a moderately agressive organic solvent. i.e. probably good for varnish but less useful for salt/water etc. Link to comment Share on other sites More sharing options...

The only thing alchohol does is act as a catalyst between the water and gas, allowing the two to mix and the mixture to be run thru the combustion cycle. The lubricant could be anything. A teaspoon of kerosine in the Coleman Fuel will probably be sufficient. Has anyone bought a gallon of Colemean Fuel lately... price?? Link to comment Share on other sites More sharing options...
Winesap7 Posted October 16, 2009 Share #14 Posted October 16, 2009 Had the same problem on mine and tapping the carb in question solved the problem------long enough to make me think I solved the problem, my drains were also plugged. I would also suggest you check your fuel filter if you haven't. I didn't and ended up having to remove my carbs for a gooood cleaning, I couldn't believe all the trash in them and my fuel filter was really really bad, no telling where the fuel we get comes from or the condition of the storage tanks. Good idea on the Coleman fuel as I have not found Seafoam down here, is it a automotive or a marine product? I wonder how does the Coleman fuel affect the rubber parts in the carbs?

Seafoam here (Reno, Nv) is available at Autozone and Napa auto supplies....Seafoam claims it can be used in just about any gasoline engine, even in lawn mowers..Not sure about diesel Link to comment Share on other sites More sharing options...
