#1: Float Bowl (SOLVED) Author: Losin,

Posted: Tue Apr 20, 2010 6:39 pm

Ok, so I took the carbs apart (how many posts start like this), deciding to functionally and cosmetically make them 99%.

Started with cleaning the bowls, the first one the pilot hole opened up fairly easily. The second one however, will not open up. I started usng a wire, like I did on the first one. Now I'm using the torch tip cleaner (I assume everyone meant the ones that look like drill bits), using gentle pressure I cleaned several times in each directtion. Nothing. As I applied pressure from the direction that the screw sets in it, hitting the small hole inside the bottom, I began to get resistance. I turned the bowl over and noticed copper, brass, whatever, shavings.

My question, how hard do I persist at opening the hole? Is it possible that it became closed by someone breakng an adjustement screw tip off in there? As long as I keep the hole size approximate, will it work?

Thanks ahead of time,

Rus

It is possible that the person who drilled out the plug went deep & hit the brass screw & buggered the head & didn't clean it all out when removing & replacing the screw. That happened to me only they just gave up because they could not remove or back out the screw. Screw tip could be felt inside the carb throat. Cylinder could not run any leaner. I managed to remove the screw, but there were some small shavings in there that I blew out with carb cleaner & canned compressed air (computer keyboard cleaner stuff). Might give that a try. Be sure to wear safety glasses if you do! Good luck.

I mis-spoke, but what else is new. The clogged part was where the pilot tube extended in to the bowl. I got it clear, but I still would like to know what's and acceptable amount of drilling on that spot.

Can you post a pic of the spot you are talking about?

Hey Xumi, here's a pic. I went ahead and drilled it until it was clear. I made sure that both bowls have a hole that is identical in size and depth. I can only imagine that it was really clogged and I hit the sides as i was drilling it and that's where the shavings came from. I'll know in a couple of hours if I really f'ed it up when i try to tune it again.

Thanks for the pics - will be curious how you came out on this one.

Ditto on that, Xumi. I have never drilled there, just used the spray carb cleaner & compressed air with the little tubes jambed into the holes to clear them after soaking in carb cleaner.

Same here packman - pretty much exact same technique I used.. never heard of one getting impacted so bad it had to be drilled before. The worst I ever saw was a bike that laid on it's side for 10 years - the carbs were filled with dried mud (bowl was completely full)... had to soak the bowls overnight, but they came clean eventually.

Congrats, Losin!

Wasn't criticizing your technique.. was waiting to see what the results were. If it runs well, i may try it on the next buggered up carbs I run into - well, ok, not sure if I'm that brave -

Good job, bro. Congrats on getting it running.

I'm glad it worked for you too. First time Graz told me to use torch tip claners I had no clue what he was talking about until I got to the hardware store. Things work well. Try to keep them clean & clear from now on & ride safe.

Tahnks Xum and Pack. It hadn't been cranked in 8 years, and the PO said he was having probs with it then. He also told me the "oil tank" on the side of the bike was in good shape. Thanks for the encouragement.
