Motorcycle Repair: Follow up Question on 70 Trail 90, bill silver, vapor lock

Question
As you indicated I put a little choke on when bike was missing. Running became much better. I had previously checked the float level to be .78"/20.0mm as per spec. I'm assuming the main jet, a number 65 should be verified and if verified to be a 65 then change to a no.66.Should I change idle jet?
I'm not sure if the various jets are available locally. Any suggestions where these can be procured?

Answer
Claude... check to be sure that the fuel tank is venting properly through the gas cap. They will lean out and vapor lock when they don't vent properly. If there is not blockage in the petcock, fuel lines or behind the float valve, then you can try the next size jet, which is probably a 68. Honda doesn't usually supply them in 1 size increments.  www.westernhillshonda.com is a good source.
