Yes i think it needs the smaller cutaway on the front carb to help draw in fuel from the float bowl. I remember I did try a number 3 slide on this one but it seemed too rich at the time. The slide in there now is slightly larger than a 3 so I will run with that today and see how the bike performs. It starts up ok, just when it is hot it struggles to run on both until you get some airflow back through to cool it down. It might be possible to fit a simple sheet metal baffle to keep the heat getting to the bowl from the front cylinder muff/head but I'll try this first to see if it is better.
Hi Greg
I’m enjoying my first ride on my new bike. I’m having exactly the same problem as Rodney after a brief stop. The weather has been cool and my bike has the insulated float bowl.
My thoughts are that most of the heat would be coming by conduction via the stub and the insulation could even hinder cooling. I believe that the fuel is vaporising and creating pressure that is holding the float valve closed. I’m going to try more breathing capacity in the cap. I’ll also try the tickler after a brief fuel stop to allow fresh fuel in.
The bike is running sweetly after a bit of carb fiddling although I still haven’t found the settings for first kick starting.
It’s a credit to Neal and Rodney’s thought and skills.
Cheers Bill
