Bystarter problem - 87 Spree

GaryMpls · Post by **GaryMpls** » Mon Jun 30, 2008 4:17 pm

I've got an 87 Spree that I couldn't get started. I pulled the bystarter out and held my finger over the bystarter hole and it started. It would continue to run as long as I held my finger over the hole. If I put the bystarter back in, it would run for a few seconds and then die.

I installed a new bystarter and now it will start and run fine with the bystarter wires disconnected but when I connect the wires it won't run at low speed and will eventually die.

I understand that as the bystarter warms up it should lean out the fuel mixture. I've tried to adjust the idle mixture but it doesn't seem to do any good.

Any ideas why it won't run with the bystarter connected?

Clean carb, keep air screw at stock setting. Do you have a complete un molested air filter assembly?

I just recently cleaned the carb and the air filter is stock.

Clean it again, whats your needle set at?

The needle is in the stock position. I have never moved it.

Because the choke is on when the bystarter is disconnected and goes off when the bystarter is connected, is it a logical assumption that because the bike runs fine when disconnected and dies when connected that the idle circuit is plugged? It would be getting gas when choke is on and not getting gas when choke is off.

Because I have cleaned the carb several times, is there anything special I need to do to clean the idle circuit?

Clogged pilot is VERY logical, check that it passes light with a flashlight in a dark room its only a pinprick when its clean.
