trialtrial Posted November 22, 2011 Report Share Posted November 22, 2011 I just got a ty250 mono. Great condition. Total pain to start. I pretty sure the carb needs cleaning as the float bowl overflow keeps dumping out gas. Any tips or tune-ups I can do to make this an easy starter? thanks Quote Link to comment Share on other sites More sharing options...
lineaway Posted November 23, 2011 Report Share Posted November 23, 2011 You have already have the right idea. Carb is clogged up with old gas. Make sure the pilot jet flows fuel. Quote Link to comment Share on other sites More sharing options...
trialtrial Posted November 23, 2011 Author Report Share Posted November 23, 2011 (edited) Well, well - here is the explanation... This green crap is on the carb, float and up both the jets. Any clue how I can get this green crap off? Carb cleaner does not do a thing. I need some kind of acid that will not harm brass or aluminum alloy. I guess I'll have to hunt down a carb rebuild kit. It's a TK carb - any clue where I can get rebuild kits for this in Canada? Edited November 23, 2011 by TrialTrial Quote Link to comment Share on other sites More sharing options...
mattylad Posted November 23, 2011 Report Share Posted November 23, 2011 The best way is find somewhere with an ultrasonic cleaning bath. You could also try false teeth cleaner (such as sterident) or the likes which is pretty good Dont forget that internal passageways may also be clogged so blow out with an air gun Quote Link to comment Share on other sites More sharing options...
feetupfun Posted November 23, 2011 Report Share Posted November 23, 2011 You could try a few more different solvents. There is bound to be one that works (alcohol, acetone, toluene, ether, citrus cleaner, hot water and detergent, dry cleaning solvent.....

lineaway Posted November 23, 2011 Report Share Posted November 23, 2011 It can be done with no parts unless the float bowl gasket is ruined. If you have a stiff metal brush, pull out one of the bristles with pliers. That gives you a strong enough wire to clean out the main jet and pilot jet. Do not forget the small passageway on the side of the bowl.A small wire brush or a steel dish wahing pad can clean most of the green off enough to make it run well again.

trialtrial Posted November 23, 2011 Author Report Share Posted November 23, 2011 (edited) Thanks for all the replies gang. I tried lacquer thinner last night - with some success on the aluminum - but nothing on the brass. I found that ultasonic cleaners are quite cheap so I got one coming tomorrow - that'll be fun! (I love tools almost as much as riding...) Edited November 23, 2011 by TrialTrial Quote Link to comment Share on other sites More sharing options...
jon v8 Posted November 23, 2011 Report Share Posted November 23, 2011 I bought an ultrasonic tank a while ago as my brother bought an RGV500 Yam and an RG500 Suzuki,then asked me to go right through them as they had both been in storage.Then a couple of people saw it in my workshop and it got plenty of use.... But one point to note is that the detergent I bought made the cad plating go dull on a couple of things,so try a few things first before doing anything special. They do do a good job though. P.S. I'm like that with tools,I think a milling machine next. Quote Link to comment Share on other sites More sharing options...
trialtrial Posted November 25, 2011 Author Report Share Posted November 25, 2011 Check it out - 20mins in the ultrasonic machine with a solution of 10% simple green and tap water. I am impressed. Just working on the Brass now - I think that'll require some special solution. Jon - I know what you mean about the tools. Any special mill in mind? I bought an Rongu RF45 and LOVE it. Not cheap though... Quote Link to comment Share on other sites More sharing options...
