There was a brand new old stock set on ebay this week- I haven't checked to see if it is still there. buy it now was $400 (ouch)

There is a carb cleaning product that comes in a gallon can with a mesh tray in it- you just put the whole thing in and let it sit for a day. Cleans up everything nice. I bought it at autozone.

Your carb is definitely not letting gas in- it is either the float bowl valve being stuck or the float itself is either not adjusted correctly or is stuck closed. does any gas get into the float chamber? if not the gas isn't coming down the hose, or the valve is stuck closed. If there is gas in the float chamber then your jets are stuck closed.

Guitar strings work good for poking through the little passages.

The bowl fills. With the needle out and pressure on the vents, fuel comes out the main. This is all trouble with it idling for now. With it running on one cylinder and the choke all the way on, if I give it a slight amount of throttle, it will die. My new lines are clear, so I can see flow.

If been using some spray on stuff that is incredible. It is basically toluene and acetone. It is killing me that I don't have an air gun to blow everything out.

THATS your problem

when you really overhaul carbs, you need to disassemble them completely, then submerge and soak them in cleaner... the spray stuff can only clean what you see.. and you end up with something like what you have now..

goto advance, i know they carry it.. on hte shelf near the carb cleaner is a paint can looking thing.

its a big can of carb cleaner with a basket in it... lift the basket up, set the jets, bodies, bowls, everything not rubber or plastic, in there... and drop it in... agitate it a bit every few mins.. and in an hour or two, it will be perfectly clean everywhere.

I don't know much about guitars but if their strings are steel you do not want to use them as picks because they can damage the soft brass jets. Instead cut a piece from an old scrap electrical wire and strip back the insulation. Since the wire is brass it cannot damage the jets.

Also I have had very good luck with a carb cleaner that is manufactured by Yamaha. It comes in quart bottles and is diluted with water. Hawk carbs are small so you can easily find a small container and submerge them overnight. Also the cleaner can be poured back into a jug and used again and again. Good luck.

Once it warms up on the one cyl and gets to where you can shut off the choke does the second cyl fire? This is what my bike does. But as I said, the more I run it the better it gets. Anyone know if the slow jet is the choke jet? If so that is where I need to look, and if your bike is acting the same as mine look there. Here's the parts diagram. http://hawkworks.net/hawkfiche/carbu...omponents.html

Well, I'm kind of stuck. The only reason I haven't dipped them, is I can't. The PO tore up the area around the pilot screw along with the screw. I can't remove it and therefore can't remove the oring either. That won't last a night in dip. Oh, and that is on the functioning side.

All this teardown and assembly is killing my bowl gaskets. I see in the above part list that it is listed at $30, but from the dealer here it is $80 and took 4 weeks to get. Has anyone used something else to seal the bowls? I already had to toss the phillips screws on the bottom and use cap heads.

I got my eyes on the ebay set, but I am going to have to sell something to pay for them. This bike has sucked down the last of my money, and it was suppose to be a money saving ride.

The Yamaha carb cleaner is designed to not damage the carbs, O-rigns, diaphrams or gaskets. Back in the late 80's Yamaha accidently shipped an entire model year worth of motorcycle without draining the carbs after their function test in Japan. Since Yamaha didn't want to pay the dealerships labor to rebuild the carbs and didn't want to pay to produce replacements they created their own carb cleaner.

The goal was to produce a cleaner that would be effective without have to disasemble the carbs. It is safe to pour into the carbs through the fuel line and let stand. I say dunk em they should be fine.

call JD hord... my bowl gaskets were junk too.. i dont recall how much i paid, but they're cheap.... much better then trying to gunk something together.

how bad is the pilot screw area? can you take a pic of it? is it just that you cant get it out, or is it fubared where it threads in?

**Beck** · 07-20-2007, 10:45 AM

I'll look into the yamaha cleaner next week. That's some good info you provided.

The area around the screw is messed up. It looks like a retard tried taking the welch plug out. All the chiseling they did, fused in part of the old plug. I would have shown a pic, but I've got the carbs back in, and I can't get an angle the camera likes.

I haven't tried running it again, because I'm having fuel line trouble. The tygon won't stop leaking even with the clamp on. The regular fuel line I just purchased is too big to slide past the carb bodies. This was the last straw, and I'm taking a break before I smash this #$%& with a hammer.

**motorcycleman** · 07-20-2007, 11:58 AM

Patience, my man! You'll get it going with some help. Put out a call for the carb in buy sell trade. Someone must have a spare (Doc?)

When I start my bike I have to wait for the one cyl to warm it up enough to turn off the choke... patience is required. Once it is warm enough and I can turn off the choke, both cyls fire and the fun begins! Like yours if I try to give it gas with the choke on it stalls. I know, I should fix it, and I will. Someday when I'd rather wrench than ride

float bowl gaskets are available cheap from a company called K&L supply...............every 'cycle shop knows about them.

**squirrelman** · 07-20-2007, 01:55 PM

float bown gaskets

float bowl gaskets for hawk are available cheap from a company called K&L supply...............every 'cycle shop knows about them.

the float bowl gasket kit is labeled as fittingVF750F Honda, K&L part # 18-2675, kit has 4 gaskets.

i'm a minor expert on carbs and cleaning (presently unemployed), so, i'm thinking maybe i could clean yours and test them out on my Hawk.......how about$85 to clean, and $25 to test on my bike??
if interested, just PM me and figure out how best to send them.............

im not going to pretend to be an expert of any kind, but i did work in a vintage bike/vespa shop for a summer... ive taken apart alot of carbs (strangely enough my hawk was the only CV carb though.. lol)

maybe i should swing by and look at it? if nothing else, its another hawk i can gawk over.

**Beck** · 07-24-2007, 05:01 PM

I went out of town, and a family member was suppose to bid on those ebay ones. Eventhough I stressed how critical it was, he decided he was smarter than me and didn't bid. His logic was, I could bid on the next set, not realizing how rare of an opportuninty that was.

Before I get judged anymore, I would just like to say this has been a sore for 7 years. You have no idea how many hours have been put into this and all the 'experts' that have walked away from this bike without a solution. I know none of these comments are meant in a harmful way, but I am reading into this, that it may be coming across as though this is my first bike and i just got it. I wanted to wait to post in the introductory area until I had the bike running, because really, at this point it may get parted out.
