well it helped me at least knock that off the list of posibilities. i was able to blow air down the needle valve hole and feel it coming out of the needle hole and those 3 holes, so they are clear.
Thanks
Does the (what is labeld as starter jet) do anything other than choke?

[bikerphil]

Starter jet is for the fuel enrichment circuit, sort of like a choke, except it adds extra fuel instead of choking off air. Not sure if it contributes to anything other than cold starting. Diagram is courtesy of Topcat.

OK!!! i put the old #1 carb that came with the bike and it ran so much better. i synced the carbs, off a little, and rode it around the block. if i let it idle for 5 sec. or so it will do the same thing it has been doing but not as bad, i can get throught it much easyer than befor, so i was right its the carbs, but i still dont know why, i need another #2 carb anyone have one they want to sell? thanks for all your advise, made me feel like i was not alone.

Just a thought, you stated that you have cleaned the carbs repeatedly. Did you remove the float valve seats? My '78 has filter screens on the inlet side of the seats. Carbs 1 and 2 share a petcock from the tank and may both have clooged inlet screens. Again, just a thought.

[raqumup]

Yes I do know about the tiny screens at the fuel inlet and they are clean. But as I said in the last post. The old carb body seemed to fix the problem with #1 now I just need to get a carb body for #2 and I think I will be good to go. Bu thank you for the advise.

Yes that small hole in the carb bowls are clear. Just did a compression test
180 180 155 175 and I did a leakdown test
5% 5% 5% 3-4%. Keep in mind that the problem ones are the 180 and 180. As far as I can tell the spec is 142 with a max difference of 14. I know I am outside the difference but the one that is out works just fine. I am going to try to sync them I have the mercury tubes. I don't think that is it because I don't see how the can get out of sync from just sitting for 5-6 months but we shall see. Thanks for all the help guys I really appreciate it

I read here somewhere (TC I think pointed out) that higher than spec compression (without any mods) could be carbonized combustion chamber.
Maybe 1 & 2 carbs running richer causing rhe chamber to carbon up.

yea i am aware of that as well but i did look down in each cylinder with a bore scope and that is not the case. i am sure it was the #1 and #2 carb bodies. that is all i swaped out and it runs fine now.
thanks

Run a compression test and check the valve clearences.

I believe that at least two of those holes go to the enrichment system, I believe the third one is to the pilot system.

Its funny how a couple of months can make uncertain the memory of this old fart.

I believe that I read that in Kats Karb info here on channel 11.
